I've been so happy with this company that I've written them a few reviews in other places on the Internet.
Our furnace stopped working in what seemed to be the coldest day so far. I know, living in LA - could be worse, but it was pretty cold for our kids. I called A.Q.B. Air the next day and he was out pretty quickly.
They gave us an awesome price and to be honest, i would have paid them a lot more for the work he did. really, the furnace worked better than it did before it broke down. We could never get heat to our third bedroom, but after he got it working again, sure enough, hot air is now blowing all the way to the back of the house. I don't know what he did, but A.Q.B. Air has made our lives a whole lot more comfortable.
I would hire these guys again, no questions and refer them out to anyone who needs HVAC work.
