* That's a 6th star since 5 is the limit. These guys are that good. Don't hesitate and don't bother looking any further. If you need HVAC work done, call Queirolo's NOW! Our AC has been acting up for several years. Now that we have a baby in the house and another one on the way it was time to take care of the problem. I happened to find Queirolo's by googling for AC repair in Stockton and I am very glad I did. David Queirolo and every one of this team that we came in contact with are all very pleasant, professional and know what they are doing! They didn't just come out and stick us with the most expensive repair they could imagine. They took their time diagnosing our issue over the course of several trips (our issue is intermittent and not easily identified), trying different small fixes along the way. Our AC unit is actually quite a bit undersized for our house (thanks a lot Ryland Homes), and when it finally gives up, Queirolo's is definitely where we will be going to have our system replaced! We would like to thank the whole Queirolo's team for making this such a positive experience! You guys are the best!
