Sierra Air has always come at short notice when we have had emergencies. Last Summer, our air conditioning went out when it was over 100 degrees out, and I have two kids who can't be in the house when it's too hot. Ray came out himself to fix the AC.

He's fair on pricing and upfront about the unit. He tells us what needs to be done, what doesn't need to be done, and how the unit works. He's always very friendly and answers our questions.
