How Long Does It Take To Install A New AC System?

One of the most common questions from the customers is regarding the time taken to install a new central air conditioning system. While it takes an average of 4-8 hours for a technician to install a new air conditioner, this is just an estimate. The time required to install an HVAC depends on a variety of factors.

Factors affecting your AC installation

So let’s go over some factors that might impact the installation time, including:

  • Size of the home or building

The size of your home is one of the biggest factors in determining how long it will take to install an HVAC. As expected, the larger the house, the longer the time frame. This is because larger homes require larger HVAC units, and in some cases multiple units.

  • The layout of your home

The size of your home often contributes to the length of time for your AC installation. However, the layout of your house also affects the amount of time needed for installation. This occurs when the layout makes it difficult for technicians to reach critical areas when installing a new device. This is because the more difficult it is to access important locations, the longer it will take to install.

  • Type of installation

If a simple system replacement is needed, the required time will be shorter than if the installation required a system-wide replacement. But if you need the ductwork to be installed, or fully HVAC system installation, the process will take longer than a simple replacement.

  • Location of the unit

If you live in a building with a high roof, it will take a little longer. These types of buildings usually require a crane to lift the HVAC unit to the roof for installation. HVAC companies often have additional technicians for large installations and Air Conditioning Maintenance in Los Angeles.

  • Existing ductwork

Existing ducts can impact installation costs depending on their condition. If there is a leak or if the zone control system is not working, it is required to perform the repair prior to installation.

Before installing a new air conditioner, repair work must be done, which further increases the installation cost.

These potential complications can also affect the cost of installing a central air conditioner. There are too many variables to discuss how much each will add to the installation cost. If your home has any of the above issues, it’s best to consult an air conditioning repair agency to deal with the installation and repair process.


Regardless of all the details, you should always get a quote from your service technician for the relevant price and duration. Once you have a schedule, you can confidently plan your installation and get your technicians to work with better ideas about exactly what needs to be included.
