Very pleased with the repairs & service to commercial unit. Professional and honest. Fairly priced. Experience and reliability counts!

They're our go-to HVAC service provider for our 4 locations. They're great!

Professional all the way from first meeting to final setting of thermostat
Arrived on time
Everything went smoothly

I had a ductless mini split installed in my garage. They arrived on time, did a very nice job with the installation and cleaned up before they left. Thank you!!

We have used AirOstat for the first time and so far went well. They were very responsive and also charged with a reasonable price.

Armen was great, he diagnosed and solved our AC problem super quick and it was fixed within a day

As the first time, Armen was kind, professional and very effective. i am glad I called AirOstat

Excellent service. fast and quick response to the service request.
Staff and tech are very professional and courteous.

Armen is the best! Greatest company, they always come so fast which is much appreciated in Los Angeles !

Our thermostat and heater were disconnected and did not work appropriately. Just one call and they set appointment quickly and repaired it quickly.

Very knowledgable and were able to get exactly what we wanted done. We needed an upgrade on our units as well as larger ducts and Air-O-Stat was able to provide us with everything we needed. Including following up several months later to make sure we were happy and to go through a maintenance check of our new units.

My call was answered by Ms. Yvette. She is incredibly knowledgeable and helpful. My cooling system was fixed the same day by Mr. Armen the technician. Along with being knowledgeable, he is also incredibly helpful.
The next day, a friend of mine is looking for HVAC company who she is having problem with her cooling system. I recommend AirOstat to her and shared with my experience with AirOstat. I will highly recommend this company. Thank you for an excellent service.

I can't say enough about how incredible AirOstat is. Armen has been servicing our HVAC for a couple years now and is incredibly knowledgeable, friendly and accommodating. The first time I called AirOstat, it was during a heatwave and our AC had conked out. Armen show up within the hour and completely put us at ease. Our AC was back on shortly after that just in time for our 2 year old to go to bed : ) I will be working with AirOstat for the rest of my life.
