Our Customers Love Us

I had them replace my 30+ year HVAC system last month and they did a very good job. The installers worked very hard in incredible heat and in a very small attic space, I felt sorry for them. Overall they gave me a good price and I would recommend them.

- Christy G.

Monrovia

Service was excellent.

- Annie S.

Sierra Madre

I have been meaning to write this glowing Yelp review for quite some time, but I’ve been too busy enjoying my working air conditioning.  Eric arrived on time, and was pleasant, thorough, and fast.  

- Jennifer R.

Pasadena

I’m very satisfied with the solutions presented by the Air-Tro team and equally satisfied with the installation.

- John M.

Los Angeles

We’ve been using AirTro for over 15 years. They are reliable, dependable, and work efficiently. I highly recommend them.

- Mariann N.

La Canada

I’ve had an HVAC and a Mini Split installed. Both good quality, good price. The people are easy to talk to. I highly recommend this company for their people and their service.

- Xheryl D.

Altadena

It was painless and fast, and the guy was intelligent and courteous.
