It’s Time To Dust Off Your HVAC Cooling Unit

In some parts of the U.S, the worst of winter’s cold weather has passed or is getting close to being history. By default, that means spring is right around the corner, and warm weather cannot be far behind.

While a heat wave is unlikely to hit you anytime soon—although who can be sure these days?—it is important to be prepared for one ahead of time if you live in an area where you rely heavily on your air conditioning unit for a substantial part of the year. Consequently, we have put together a checklist you can do to ensure your HVAC unit is ready the moment that first hot air arrives. Read on to learn more.

Filter It Out
It is a good move to replace your filters on a regular basis, so we recommend changing yours once a month. This simple and relatively inexpensive step will ensure your unit is operating as efficiently as possible.

Keep Things Clear
Water is an important part of the cooling process in your HVAC unit. Consequently, it is imperative that you keep that liquid flowing smoothly. We recommend checking your drainage hole at the base of your unit, usually located beneath the evaporator fins. If it seems to be clogged or partially blocked, use a paper clip or something like it to poke through it to free any sludge and keep things moving.

Dry It Off
An often overlooked but simple and effective step that is key, particularly at the beginning of every season, is to check your dehumidifier. Again, built-up moisture is the enemy. Accordingly, take the dehumidifier’s lid off and let the unit dry completely, then vacuum every part of it. This will ensure it operates at top capacity.

Keep Your Fans Happy
Clean your bathroom fans so they pull their weight in getting warm, humid air out of your living space and take some pressure off your HVAC unit. Just turn off the power, clean the unit with a rag or toothbrush and some water and let it dry.

Seal Team
Finally, caulk around your windows to ensure you are not letting your valuable cool air out and the enemy hot air in. This is also yet another way to lessen the strain on your cooling unit.

So don’t delay and don’t assume all is well with your HVAC unit. Make a list and have a reputable service professional, like those here at Precise Air Systems, check it twice. That way, you can relax in cool comfort when that heat wave does hit.

Mid-Winter Steps You Can Take To Prepare Yourself For Potential Heating Woes

For people in the Northern Hemisphere, the coldest days of winter are starting to kick in. This can cause many of them to rely more heavily on their home’s heating system. Some even worry how they would survive even for a night if their heating system breaks down, especially if they are ill, elderly or shut-ins.

While we can’t always control what happens with our appliances, we can take a number of steps to minimize the discomfort and even be prepared to endure the misfortune in relative comfort. Here are a few great steps you can take to ensure you stay warm all winter long:

What’s Up, Doc?
Having a professional HVAC technician do a check-up on your unit before it breaks down is always the best first approach. So if your unit is operating sufficiently at the moment but you have reason to worry that it may not last the winter, set up an appointment with a professional now. Having a tune-up done before any potential problems develop will give you peace of mind, and perhaps even a warranty for any work done, so you will be covered down the road regardless of what happens.

Hit the Books
If you can’t have a professional take a look for financial or other reasons, it helps to know as much as you can about your HVAC unit. Go online to read up about the type of unit you have and learn what you can do to troubleshoot or identify potential problems before they develop. Being more educated about your unit will also help you ask questions and understand more if a technician does visit. If you can’t get online, buy a book at a local bookstore or check one out from the local library.

Have a Backup Plan
Finally, having secondary heating options in the event your HVAC unit does break down can be the difference between extreme discomfort and relative, or complete, warmth. If you are able, having a generator on hand to power a heating source is a great backup. In addition, so is having one or more portable electric heaters. These units are small and relatively inexpensive, and one typically heats a room sufficiently. Having any or all of these backups are great insurance.

As always, having more information is the best approach to dealing effectively with any potential problems. If you’d like to know more or schedule an appointment, contact us here at Precise Air Systems. We’ll make sure you rest easy all winter long.

Last-Minute Maintenance Checklist For Your Central Heating System

Last-Minute Maintenance Checklist For Your Central Heating System

It’s getting cold out there, and that means the windows are shut for the season, the sweaters and jackets are out, and the heat is on. In fact, your central heating system is due to get a workout for a number of months. So, is yours in tip-top shape?

In a perfect world, you should have your central heating and air system checked by an HVAC specialist twice a year—once prior to the winter and once just before the summer heat kicks in. If that’s not possible, make sure you have it checked at least once a year to avoid any unforeseen breakdowns.

Nonetheless, there are a handful of steps you can take on your own in between professional visits to ensure your heating system is operating smoothly. Read on for a checklist.

Gauge Your System’s Efficiency
No matter what kind of heating system you have in your home, every check-up should start with testing the thermostat to make sure it is operating smoothly. You can do this by turning up the temperature. If you hear the furnace turn on and run indefinitely, your system is healthy. If it stops running after a couple minutes, the thermostat could need to be recalibrated or replaced. If that’s not the cause, your furnace could be overheating and being automatically tuned off by a safety device. Either way, you should contact a professional to diagnose and repair the problem.

For the Forced Air System
Regardless of how your heating system is powered, the most important thing is to keep your airways and interior of your system clean and free of debris and your blower unobstructed. These are all measures that need to be addressed by a service professional. However, you can do your own quick check on the quality and state of your filters every month by making sure they are clean. It is also recommended you replace them every three months.

Oil Furnaces and Hot Water Systems
For oil furnaces, it’s important to have the oil filter checked and replaced regularly, but this clearly should be undertaken by a service professional. With hot water systems, you can test them on your own by turning up the heat and then checking the valves and connections to determine if there is a leak. If so, or to treat any other issues, call a professional.

So don’t tempt fate. Contact Precise Air Systems today and make sure the heat truly is on.

Often-Overlooked HVAC Winter Maintenance Tips

Often-Overlooked HVAC Winter Maintenance Tips

Depending on where you live, summer can be the season that puts the most strain on your HVAC unit. Regardless, it often seems as if your trusty cooling machine has to battle through the blistering heat, often without a break for weeks at a time. Many homeowners are then thrilled when the weather breaks and they are able to give their HVAC a rest and, soon thereafter, clean it up and shut it down.

However, that quick once over is often doing your unit an injustice. The truth is, many homeowners overlook a handful of necessary and effective measures they can take during the winter to keep their mean machine in tip-top shape. Here is a list of a few overlooked actions you can take during the cold-weather months so there are no surprises at other times of the year:

Clean, Clean, Clean
Many homeowners clean around the outside of their unit after autumn’s leaves make their descent and reach their final destination. If they are smart, they also clean out the inside of the unit, too. However, it is vitally important to keep the area in and around your unit clean and debris-free throughout the winter, whether it experiences a build-up of dry, dusty debris, dead branches or even snow. So make it a point to clean around your unit once or twice a month, even for just a few minutes, to prevent any potential complications in the future.

Insulate Your Attic
This is an often-forgotten step, as it does not apply directly to the heating unit. Still, adding a fresh, thick layer of insulation to your attic can cut your heating costs and the demand on your machine greatly. In addition, insulation works both ways, keeping the warm in and cold out during the winter and vice-versa in the summer. Isn’t that worth the time and effort?

Get Your Ductwork Cleaned
This is imperative, as not only can dirty ducts spread allergens and dust throughout your living space, but they can decrease your heating unit’s efficiency by as much as 15 percent. So contact a professional and have this service done periodically so that you and your family can breathe easier, literally and figuratively.

As you see, these steps are as easy as pie to complete and offer you tremendous peace of mind so you can enjoy the changes of seasons without fear.

Follow This Winter Maintenance Program To Keep Your HVAC Running Strong

Follow This Winter Maintenance Program To Keep Your HVAC Running Strong

You survived the blazing heat of the summer and are thoroughly enjoying the temperate days and cool nights that autumn brings. You’re also happy to give your HVAC unit a rest, as it worked overtime in the relentless summer heat. However, before you throw a cover on it and put it out of your mind, consider having a professional maintenance tune-up before winter fully kicks in, even if your unit performed flawlessly all summer long. It will lower your bills, prevent costly repairs, spare you the discomfort of a breakdown and ensure your unit has a long, productive life.

If you decide to do the maintenance yourself, follow these simple but important steps:

Turn Off the Power
This seems like a no-brainer, but we want to reiterate it here so you do not get the shock of your life.

Remove Leaves from the Fan
Unscrew the fan cover from the top of your exterior HVAC unit and clean out all debris in the fan and underneath it in the unit. This usually consists of dead, dry leaves, which can clog your fan and unit and compromise its operation.

Clean and Straighten the Fins
The fins are the gaps, or gill-like designs, on the exterior sides of your HVAC unit. They can become clogged by dust, dirt and debris, which can prevent the free flow of air into and out of your unit, both of which are necessary for its optimum performance. In some cases, the fins can become turned or bent. In this case, use a butter knife to gently straighten them.

Clean Around the Unit
As a preventative measure, sweep and clean the grounds around the exterior of the unit to prevent any future clogging.

Clean the Evaporator Coil
Moving to the interior side of things, clean the evaporator coil using coil spray cleaner, available in home-improvement stores, to remove dust and grime. Then wipe the coil clean. Finally, dry the liquid that has fallen onto the drain pan and flush it out with a soap, water and bleach mixture. If it drains well, then you’re good to go. Otherwise, you’ll have to check and unclog the evaporator drain.

Change the Air Filter
Last but not least, change the air filter, an easy step that should be done twice a year.

You can now turn the power back on and make sure it is running smoothly. Then feel free to put it out of your mind. Your work is done.

How to Make an Efficient Transition From Summer Heat to Cooling Fall Temps

How to Make an Efficient Transition From Summer Heat to Cooling Fall Temps

For better or worse, in most of the U.S. and North America, the summer is ending. That means those balmy, sunny summer days will soon give way to shorter days and cooler temperatures. However, just as the transition from heat to cool is gradual, so too should your transition be from blasting your air conditioning unit to not using it at all. It’s not rocket science, but it is worth knowing the best way to go about it.

Read on for a few valuable tips for weening yourself off your cooling unit in a way that won’t disrupt your comfort or hurt your wallet.

Appreciate Your Fans
Whether you have ceiling fans or window units, this is a great way to start enjoying cooling effects without having to turn on your air conditioner. This is particularly true if the hot portion of the days are getting shorter. So, pay close attention to the subtle changes in temperature and consider using your air conditioning only when it is truly warranted. Then, use ceiling or window fans during overnight hours, and always make sure to turn off all units when you leave the house.

Throw Some Shade
Sure, the heat from the sun isn’t quite as strong as it was a month or so ago, but it still can heat up your living spaces. This is particularly true if you have lots of windows that allow direct sunlight to shine through. Consequently, if you leave the house in the morning, make sure to draw your curtains or blinds to diffuse the sun and the associated heat it introduces into your home. It will keep your home a more even temperature and reduce the amount of time and energy it will take to cool your home when you get home.

Feel the Heat
Finally, be proactive and do a test run of your heating system before it’s too late. If there are any issues with it, wouldn’t it be better to know about them in the transition of the seasons than after it has already turned chilly and you are shivering? Accordingly, turn your unit on, and if it seems like it’s operating at full capacity, great. If not, call your heating specialists and have them find the problem and fix it before the seasons change completely. You’ll be happy you planned ahead.

So remember, as with so many things, moderation is the key. The gradual approach will pay dividends, literally and figuratively.

Smart Ways To Conserve Energy And Cool Your House In Hot Weather

It sure is hot out there, and as much as you like to save money, you are in no mood to perspire like that inside. So you plan on turning your air conditioning on as soon as you open the door, regardless of the cost.

At the same time, you’ll be happy to know, there are some smart and easy ways to conserve energy while still cooling your house efficiently and effectively this summer. Read on to learn how.

Go Easy on the Thermostat

We know you’re hot, but avoid the temptation to spike the temperature on your thermostat dramatically lower when you come in from the heat, or ever. It is precisely these spikes that drive your energy bill through the roof. Instead, find the highest temperature you can tolerate when you’re inside, and then keep it steady while you’re in the house. When you leave, raise the temperature on the thermostat so it does not turn on while you are gone.

Use Fans and Natural Ventilation

If you live in a part of the country that cools off at night, take advantage of it. That means turning off your air conditioner, opening your windows and turning your fans on. Then, when you wake up in the morning, close the windows to lock the natural coolness in and turn your air conditioner on to your arrived-at temperature.

Keep Your Unit Running Smooth

If you have central air conditioning, clean around your unit and keep it free of debris that can clog it and cause it to operate less efficiently. Also, schedule regular maintenance appointments to keep its insides healthy and clean, too. Even if your apartment or home relies on a window or wall unit, clean it regularly to rid it of dust and allergens that can slow it down. In addition, replace its filter seasonally.

Sideline Appliances and Lights

Avoid turning on the oven on particularly hot days and opt to cook outside, in a microwave or on the stove top to prevent heating up your living space. In addition, avoid placing appliances or lights close to your thermometer, as it could pick up their heat and artificially trigger your air conditioning to turn on.

Seal the Weak Spots in Your Home

Finally, seal the cracks around doors and windows to keep the heat outside and the cool inside.

You’ll find that just taking these simple steps will do wonders to help keep your bills low and your home cool this summer.


What You Should Know About HVAC Maintenance This Summer

What You Should Know About HVAC Maintenance This Summer

As the dog days of summer fast approach, isn’t good to know you won’t have to sweat through the worst of it? As the owner of an HVAC unit, all you have to do is flick a switch, and voila! Your house is magically cool and comfortable.

However, it sure would be a bummer if it broke down or was operating at less than optimum levels.

Well, that doesn’t have to be the case. In fact, now, before the hottest weather hits, is the perfect time to run through a bit of a maintenance regimen to make sure that doesn’t happen. Read on to learn about the best things you can do to do get your HVAC unit ready to flex its muscles.

Clean Around Your HVAC Unit
This sounds obvious, but if your unit is shrouded in dead leaves and branches it could be working at less than optimum performance. Making sure air flow is unimpeded is a great first step.

Clean or Change Your Air Filter
This is another way to ensure you’re feeling the coolest air possible from your HVAC unit. Any blockages cause your HVAC unit to work harder and less efficiently than it should.

Invest in a Programmable Thermostat and Set It Wisely
A programmable thermostat allows you to establish and maintain a comfortable temperature and save energy at the same time, particularly if your home is well insulated. This is much more efficient than turning your unit on and off, which causes it to work harder to cool your living space when it is hot.

Seal Around Your Ducts, Doors and Windows
Just as cleaning around your HVAC unit is important for efficiency, so is preventively sealing around any open spaces where unwanted warm air can get in or cold air can get out.

Professional Maintenance
If you can, call a reputable company and have a professional do a more involved check-up, which usually requires disassembling parts of the unit. A few simple yet effective steps are to clear the drain, cleaning the condenser fan’s blades and removing dust and debris from the indoor evaporator coil. It is a relatively cheap house call and is worth every penny.

Ultimately, even if you follow all of these steps and find only minor things to correct, your HVAC unit will run that much more efficiently. Isn’t that worth it in the end?

How To Save Money And Stay Cooler This Summer

How To Save Money And Stay Cooler This Summer

Staying cool and comfortable through the dog days of summer can be challenging if your home has to battle the heat with an antiquated window unit. While there is some obvious installation cost associated with a new HVAC unit, you will quickly notice the monthly financial savings. The fact is, HVAC units are much more economical than window units.

If you already have an HVAC unit, you are already halfway there. Still, many homeowners fail to maximize the benefits of their air conditioner by overlooking some important yet simple steps. Read on to learn more.

Let Your HVAC System Breathe
Think of your home’s air filters as its lungs. Now wouldn’t you want to keep those as clean as possible? Consequently, you should vacuum them regularly so that warm air is dispelled and cool air glides in easily.

Take Care of that HVAC
The flip side of keeping the air filters clean is regularly clearing debris from the outside of your HVAC unit. Leaves, tree branches and other debris can cover or clog the screen and grill, causing it to run less effectively. The bottom line is that your unit needs the free flow of air in order to operate efficiently and effectively.

Fill in Those Empty Spaces
Every home, particularly older ones, has its weak points where seals are broken and air from outside makes its way inside, and vice versa. This can be a killer for your summer cooling bill. However, you can minimize or even eliminate those unnecessary costs by going through your home and resealing any cracks or gaps around windows, window sills, baseboards and doors. It is estimated that sealing major cracks can save up to 20 percent on a cooling bill.

Insulate Yourself
Adding insulation to your walls and around your ducts can work wonders for keeping the cool air in and warm air out, which will allow you to maintain a steady temperature while using a minimum of energy.

Keep It Steady
Make sure you have a functioning programmable thermostat installed. This may seem like it’s just a matter of comfort, but a programmable thermostat will help establish and maintain a constant, cool temperature that you find comfortable, allowing the HVAC unit to operate at maximum efficiency. Turn it a bit lower when you leave the house, then program it to cool slightly about an hour before you get home. This will help you avoid asking your unit to cool the house dramatically in a short period of time, thus saving money in the long run.

Ultimately, you don’t have to give up any comfort or spend extra money to ensure your home is being cooled as efficiently and cost-effectively as possible.

The Advantages of Central Air in The Summer

The Advantages of Central Air in The Summer

With summer fast approaching, now is a good time to consider how you plan to stay cool when the heat hits. If you are in a home with window or wall units, it’s especially important for you to consider upgrading your home’s cooling system now, for your personal and financial comfort. Read on to learn more about the benefits of central air.

It Keeps Things Flowing, Baby
That may sound like a vague sales pitch, but it’s one of the most important points when trying to understand the value of central air as opposed to window or wall units. The concept is actually really simple. A big part of cooling a home is introducing cool air into it, but another, equally important part, is getting rid of the hot air that’s already there. Therein lies one of the greatest values of central air.

Because a window or wall unit has one location, it can only cool the area immediately around it. If there is just one such unit in a space that is too big for that unit to cool, it will require the unit to battle, ceaselessly, to replace that warm air in other rooms and in the walls with cool air. Consequently, you may have to keep your unit running all day and night. The bottom line is that you will either use an exorbitant amount of energy, and hence, money, trying, unsuccessfully, to cool your home, or you will feel uncomfortable because your unit just can’t deliver the goods.

Central air, on the other hand, sends the coolness throughout all parts of the house, much in the same way blood circulates throughout the human body. That means once cooling is achieved throughout your living spaces, you will only have to run the unit periodically to maintain that comfortable temperature—and you will be cool and relaxed along the way.

Air Quality and Safety
Another benefit of central air is its ability to keep the air you breathe fresh and clean, flushing out allergens and humidity regularly. In the winter, the warm, constant heat will do the same while being much healthier than that created by wood-burning stoves or fireplaces. So you will breathe cleaner, healthier air as you live and sleep.

Aesthetically Pleasing
Finally, no amount of interior design can hide the unpleasant look of a dated, unattractive window or wall unit. Conversely, central air units continue to be smaller and less obtrusive than ever. The bottom line is that you, and the visitors to your home, will hardly be aware of its presence.

In the end, yes, there is a cost associated with installing a central air unit. However, once installed, it will deliver exceptional, low-cost comfort and health for many years to come. Isn’t your family worth that?

6 Top HVAC Brands And Why They’re Rated So High

6 Top HVAC Brands And Why They’re Rated So High

Making an investment in an HVAC system is serious business. First, it will cost you a substantial sum of money. Second, it will be with you, hopefully, a long time. So it is important to do your homework and find a reputable make and model that fits your needs and your budget. Having said that, it is equally important to find a good installer, as this can impact the unit’s effectiveness as much as the quality of its production.

Nonetheless, here is our choices for the top six brands currently on the market:

1) Maytag: Though it is a smaller company, this maker seems to be one of the best HVAC producers at the moment, thanks to some cutting-edge advances in its production and design. Its M1200 PSA4Bl iQ Drive has garnered praise for its efficiency and quietness. It is Energy Star-qualified and meets CEE Tier 3 requirements, plus its stainless-steel cabinet is impressive, as is its 12-year warranty.
2) Trane: This Company also gets good grades from its customers, particularly in regard to its efficient and quiet operation. In fact, the Trane XV20i uses less energy than almost any model made by any other producer. Though it earned just a 21 SEER rating, its ability to sync with and be controlled by a downloadable phone app wins it extra points.
3) Lennox: This Company maintains its standing as one of the best because of the dependability of its products, and its insistence to only allow qualified installers to install their products. The Dave Lennox Signature XC25, in particular, is one of the most efficient HVAC products on the market. In addition, it is solar-power ready, so it can be used in conjunction with and powered by solar panels. How’s that for forward thinking?
4) Carrier: Carrier’s low percentage of units needing maintenance and its generous 10-year warranty keep it in the top six brands. Its 21 SEER has been surpassed by a number of brands, but the Infinity 21 24ANB1, in particular, is winning rave reviews for its ability to extract humidity from indoor spaces.
5) Rheem: This Company continues to make efficient, cutting-edge HVAC units that have low incidences of customer complaints. Rheem also offers above-average warranties on all of its models.
6) American Standard: Yes, this Company can be a bit pricey, but you get what you pay for. In American Standard’s case, that means excellent reliability and far fewer problems with such components as air conditioning and heat pump units.

In the end, which make and model of HVAC unit is right for you depends on a number of things. Spend the time studying the market and ask an expert their opinion. Chances are, you’ll end up with a system that lasts you many years.

Portable vs. Installed HVAC: What’s Right For Your Home?

Portable vs. Installed HVAC: What’s Right For Your Home?


Everyone wants to be warm during cold weather and cool when the heat arrives. Luckily, there are a number of good options to control the temperature of your home. Two of the most popular are portable and installed HVAC units. However, which one is best for your home depends on a few important considerations. Read on to learn which might be the best match for you.



Installed HVAC units sure are all-encompassing, reaching every room in your living space and every corner of those rooms. In addition, once they are working they can offer the most efficient performance of any type of system. However, they are also the most costly to install. Consequently, if you are considering one of these units you, should think over a few things. First, do you own your home, and are you planning to stay in it for the foreseeable future? If you can answer yes to both of those, an installed HVAC system can be a good investment and increase your resale value. Another factor is whether you really need one of these based on your location in the world and the severity of the summers and winters. Otherwise, consider a portable unit, which are much less expensive and can be used only when you need to control fairly extreme temperatures for short periods of time.



How much of a living area do you have and how much space needs to be cooled or heated? This is a very important part of making the right choice in HVAC units. For instance, do you really need an installed HVAC system in your one-bedroom condominium unit, or can you make due with a portable unit? Conversely, do you really think a portable unit or two could effectively heat and cool your three-bedroom house?


Ease of Installation

Finally, how much disruption to your daily life are you willing to endure, and who would be doing the work? If you are having your HVAC installed, know that it will take some time, noise and dust to get the vents installed and the unit working, even with a professional doing the work. If you are installing yourself, it could take longer. Conversely, a portable unit is easy to install and operate, regardless of who is doing the labor.


Ultimately, you are the only one who can decide whether a portable or installed HVAC unit is right for you. Look deliberately at your space, consider your budget, and decide how much aggravation you’re willing to put up with. Then making the right choice will be easy.

5 Things To Look For When Choosing An HVAC System

5 Things To Look For When Choosing An HVAC System

Investing in an HVAC system for your home, business, or residential property is an important and necessary purchase for the health of those who inhabit those structures, and well as for the building itself. Before deciding on the make and type of your HVAC system, as well as its capacity, there are a number of factors to take into consideration, as not all units are equal. Precise Air Systems can help you every step of the way, from shopping and choosing your system, to installation and service thereafter. Before purchase, we recommend considering the following:

This first consideration is the most obvious, as what you need from your HVAC system depends largely on where your home or building is and what the climate is like there. Clearly, if you are in a northern location with long, cold winters, you will want to invest in a unit with a particularly strong furnace element. Conversely, if you are in a warm, southern location, you will want to invest more heavily in a strong air-conditioning unit.

Technological innovations are occurring quite rapidly these days, so it is important you read up on the latest breakthroughs in HVAC technology before purchasing a system. Read independent reviews of the latest products to help you decide which make and model is best for your particular circumstance.

Considering the cost of an HVAC system is, naturally, very important, but as a consumer who will be using this product for many years to come, it is also important to weigh the documented efficiency of the unit too. While some systems cost substantially more than others, their low operating cost through the years could end up saving you money in the long run, particularly as the cost of energy is extremely variable.

Again, look clearly at the price of a system, but don’t forget to consider the cost of installation. It is also important to be aware of the reputation of the company or individuals who are installing it. This one-time cost can be substantial, so you want to ensure it remains a one-time expenditure.

Knowing what the experts say about the reliability of your system, as well as the cost of repairing it, are also important to consider before making this major purchase. In addition, being aware of the reputation of those who you would rely on to do the work is equally important.

Ultimately, you can prevent problems down the road by doing a little homework about the system you buy, and the company from whom you purchase your new HVAC system. At Precise Air Systems, we always stand by our products, workmanship, and service.



The fan settings on your HVAC system have a powerful effect on your home’s air quality as well as your energy bills. You must decide whether to leave the fan on once your home attains its ideal temperature. Yes, you are making the decision between cost and your home’s comfort level; but if you’re tired of your energy bill making you weep, you might want to turn the fan off.

Two Fan Settings

HVAC systems generally feature two fan settings: “On” and “Auto.” The fan runs in conjunction with your air conditioner when your thermostat is on the “auto” setting. Forced air spews continuously from your home’s vents when the fan is “on.” It will keep running until you change the setting.

Energy Conservation

The “auto” setting on your HVAC system is an eco-friendly component designed to conserve energy and lessen the wear and tear on parts. This setting is especially designed to reduce wear and tear on the fan motor. Air does not pass through your HVAC system filter constantly when the auto setting is on, a fact that can help your filter last a little longer. Unfortunately, consistent use of the auto setting eventually causes the air in your household to become stale. Your home gets stuffy and uncomfortable unless the cooling cycle is on, making it a good idea to open a few windows. Fresh air circulating throughout the home prevents indoor air from becoming stagnant and nasty.

Fresher Air

The opposite is true when you are using the “on” setting, as the air in your home is consistently replaced. It will seem fresher, and assorted odors much less noticeable as a result. Continual air circulation via the “on” setting is ideal for asthma and allergy sufferers, as they do not have to dwell in a home filled with “old” air.

Yet pumping fresh, cold air through your home without stopping causes your energy bills to—you guessed it—spike. You will also need to replace your filters much more frequently. Additionally, more maintenance is necessary to maintain your hard-working system. This includes fan motor repairs and replacement.

The other not-great thing about keeping your system “on”? It can pull humid outdoor air into your residence between cooling cycles. This is mainly problematic if you reside in a humid climate. Whole-house dehumidification is recommended to solve this issue, though it won’t help your energy bills stay low.

Compromise IS Possible

It is possible to have the best of both worlds. Look for an air conditioner that features a varying-speed fan for better customization. You can program the appliance so the fan runs at a higher speed when the unit is on and a slower speed when it is simply circulating air.

Foul-Smelling HVAC Air Can Have Many Causes

If you’ve noticed a persistent foul stench emanating from your HVAC system, don’t allow it to go unchecked. Some odors are harmless and short-lived, while others severely injure your home’s indoor air quality and may result in bronchial problems among other health issues. Nasty-smelling HVAC air has many causes, making it important to identify the problem(s) and take action as soon as possible.

Mechanical/Electrical Issue

A smoky odor coming from your HVAC system likely indicates a mechanical or electrical issue. Moving parts, such as the fan or motor, can overheat or catch fire if the HVAC system isn’t maintained on at least an annual basis. If you think something within your HVAC system is burning and coming through the vents, shut it off immediately and observe the unit outside. Schedule an HVAC inspection and repair immediately to avoid further complications.

Mold and Mildew

Should that familiar musty scent waft out of your vents, you have a mold or mildew problem. Mold and mildew thrive in dark, damp conditions, and often form in ductwork and on coils. If the problem is allowed to continue, mold and mildew will easily spread to other parts of your home and cause a variety of health problems. You will also have to vacate your residence while mold remediation specialists rectify the issue. Causes of HVAC system-related mold and mildew include leaky ductwork, blocked drainage tubes, and poor insulation. Have a professional identify the cause and deal with the problem before it infiltrates the rest of your home.

Cigarette Smoke

If you or someone else in your home smokes cigarettes, know that the HVAC system will circulate the smoke—everywhere. Stale smoke stenches attach themselves to condenser coils and create a foul-smelling film within ventilation ducts. Special cleaning methods are needed to remove this stench from ductwork. Smoking outside of the home is also necessary to prevent further problems.


Using your furnace for the first time each year often results in an unpleasant smell throughout your home. This is due to dust settling on furnace heating elements during warm weather. The dust burns up once the system is turned back on, which is why inspection and maintenance are strongly recommended before winter’s chill takes over.

Don’t let any of the above odors permeate your home and cause a slew of unpleasant problems. Stay proactive about HVAC maintenance to enjoy odor-free vents and a system that functions at an optimal level for many years.

The Advantages of a Programmable Thermostat

Perhaps you feel like the heating and cooling systems in your home are working just fine. When you’re home, you’re able to achieve a temperature that’s comfortable, so why go and change things?

The fact is, that by choosing the simple installation of a programmable thermostat, you and your home will be receiving multiple benefits, including savings on energy bills that will soon add up to not only pay for the cost of the new thermostat, but will save you money for years to come. But saving money, though for many the most important advantage of a programmable thermostat, is just one of many benefits. Here are a few more.

  1. Increase the Energy Efficiency of Your Home: More and more homeowners are prioritizing making their home more energy efficient. In addition to saving you money, it is good for the environment. It also puts less strain on your heating and cooling systems, you’ll be able to get more life out of an older HVAC system, and keep a newer one running at full capacity for longer.
  2. Implement Precise Heating and Cooling Times and Zones in Your House: A programmable thermostat allows you to be sure that your home is at the right temperature from the moment you walk in the door, but while no one is home, the system isn’t wasting energy (and money) heating and cooling an empty home. Today’s thermostats can be programmed to set specific parts of your home to the correct temperature, so that whether some parts of the house are used less often, or there’s a desire to keep it a warmer or cooler temperature than the rest of the home, this can easily be achieved.
  3. With the High Tech Abilities of Today’s Programmable Thermostats, So Much is Possible: Today many models of thermostats allow for integration with Wi-Fi or blue tooth, allowing you to adjust the temperature from your phone, without even having to stand up, or monitor your home energy usage while you’re on vacation.


These are just a few of the benefits of installing a programmable thermostat, but as energy costs around the world go up, the annual savings are always a big draw. Every degree less that you are heating or cooling your home cuts 2% from your bill. On average a programmable thermostat will save you $150 every year.
