I had McMaster install an air cond. in a rental home in may 2015 and they did a good job. I have waited until now before writing a review as i wanted to see if we had any problems. Through all the heat this summer not one problem. I am very satisfied and will use them again.

Bill J., Santa Ana, CA Via Yelp Testimonial

Rory K., Mission Viejo, CA Via McMaster Heating & Air Conditioning Customer Lobby Reviews


I recently had McMaster air replace my older a/c and furnace with newer more efficient units,what a difference why didn't I do this sooner! I highly recommend them.

Farfone V., San Juan Capistrano, CA Via Yelp Testimonial


They put in my new units, 3 years ago. When the fan went out, in a hot spell, they did their best to get it fixed immediately.
