52 years of promises kept.
If It Deals With Air, We Deal With It. From a family shop on San Fernando Road to LA's leading Mitsubishi dealer — the standard has never changed.
Built in Los Angeles, since 1975.
Precise Air Systems, Inc. has been family-owned and operated since 1975 — more than 52 years of Los Angeles summers, Santa Ana winds, and cool coastal mornings. Through all of it, our work has carried one promise: if it deals with air, we deal with it.
Today that means complete air conditioning, heating, Mitsubishi ductless, heat pump, indoor air quality, duct, and commercial services across Greater Los Angeles — delivered by a team our customers ask for by name. Read our reviews and you'll meet them: technicians praised visit after visit for showing up on time, explaining clearly, and recommending honestly.
As a Mitsubishi Electric Elite Dealer — and one of LA's leading Mitsubishi dealers — we pair factory-backed expertise with the personal care only a family company keeps. We're licensed and insured (CA Lic #428900), and we answer our own phones: (818) 240-1737.
