"They do what they say they're going to do, and they're not a hard sell. They're a bit pricier than others, but you have a choice not to purchase what they're selling you. You can go somewhere else as a choice for some cheaper parts or new unit. I had to replace our heater. It's easy to get an appointment when you need it. They are here when they say they're going to be here, and they don't take any unnecessary time. It's convenient. They do a great job, and they do everything that needs to be done." - Ineke B.

"Just make sure the person that comes to you is correct, because the last guy gave me quote, and I was happy with that, but guy before that was bad. They already fired him. I love Dimitri, my service technician." - Paul G.

All-Pro Heat Pump Solutions Customer, 1 of 18
"So helpful, they went to the installment and beyond with helping remove and discard my Swedish fireplace for me and painting the outside piping to match the redwood walls per HOA requirements. They also set up my energy application and inspection for the city’s $2500 reimbursement. They were very clean every day with clearing out any debris left over and included an instruction session on how to use these mini splits, plus a service agreement, so I don’t have to worry about any future maintenance. What more could I want? Really great work and people to support my investment" - Rachel P.

Air Care Heating & Cooling, Inc. Customer, 1 of 129
"Joey, the owner, has a very high standard. He can take care of things that other people can't get done. For example, our neighbor was told that the compressor in their yard could not be moved and it was very visible. Joey came out with his crew and they moved it completely out of site. His policy is not to sell people new units. He has a high level of integrity. If there is a problem, he will look at it, think about it, come up with a solution and tell his guys how to do it. It is always the perfect solution. My wife does a lot of cooking and her kitchen gets warm. I asked him if there was some way to put a vent in there to cool down the kitchen. He was able to come up with a good solution and one that most people would not know how to do. I can't say enough good things about him." - Richard B.
