Client Testimonials

David & Dan were very good technicians. Everything was explained specifically. They were kind, understanding, very polite and patient. Anna Giles February 2015, Moreno Valley, CA Very pleased with Eric and Sam or their thoroughness and honesty in servicing my equipment. They were great! There are so many companies that want to sell you everything. This company was not like that. They were very clean in my home. Physical appearances were top notch. Great uniforms! Very professional. I will recommend them to all my friends.

My wife called GQ Heating and Air in Costa Mesa for our AC Repair because they’re local. They were quick to respond and before we knew it, we did not have that sinking feeling thinking “who can fix my AC” on a weekend – Thank You GQ!
