Commercial Air Conditioning Services
I unreservedly recommend this company. I recently had them replace our rooftop a/c unit, a major undertaking.
The work was flawless.
They were completely professional, on time, and patiently walked through testing the air conditioning and heating functions. Great work!!!

These days, is so hard to find an HVAC company that shows up much less does good work. You've hit the lottery if you're reading this now, cause AirOstat was not the only company that works on mini splits and general HVAC units, but they were super professional, showed up on time, called to follow up on the work done. This was a great experience for me. Thank you guys.

Armen from Air O Stat diagnosed out A/C issue within 10 minutes of arriving and then happened to have the replacement part and got our A/C working again within another 15 minutes. This is our second time having Air O Stat repair our system and they are VERY TRUSTWORTHY. Really happy with our service !!
