Get matched with top heating and air conditioning pros in Cupertino, CA

"Our annual HVAC inspection went flawlessly. The technician was thorough, friendly, and gave helpful maintenance tips. System is running better than it has in years."

"Duke did a great job at a fair price. We needed AC and decided to replace our old furnace at the same time. In addition Duke wrapped with insulating bubble wrap our old ducts that were exposed. He tied the drip line into our existing downspout in a neat fashion. I'd highly recommend him (he's a fellow submarine vet too!!)."

"I first contacted Valley to get a quote on how much it would cost to get air conditioning installed. I live in an older town home that is approximately 1100 sq. ft. They sent someone out to take a look and see what was involved. He was very professional and explained what was involved including getting permits from the city. He quoted the amount and provided me with an invoice. I contacted them 3 months later to say I was ready for the install. The installation turned out to be quite challenging due to the way my home is constructed, but Valley made it work. The service person had to stay a few hours longer but I wasn't charged anything extra for it. They stuck with the amount of the estimate that was quoted. It's only been a couple of months since the install, but I have to say my only complaint at this point is how cold it gets when I turn on the air. But that's a nice problem to have. :)"

"Air conditioner was blowing ambient air only. Tried to contact my usual HVAC company and they were scheduled out 3 weeks because of the recent heat wave. I called 14 companies to check on availability and Comfort Energy was the only one who had an opening within the week. I confirmed with them and was very pleasantly surprised. They confirmed not only the day and time, but also the exact make, model, ans serial number of the unit to ensure they had all the information they needed. In the meantime, my husband was able to get the unit going by installing a new capacitor himself, which he had done in the past, but wanted to go ahead with the service call so we could have the whole system checked out in case there were other issues. The day before the appointment, I received a text confirming the appointment time. I asked that the service technician call 30 minutes before arrival, which he did. The technician, Nasser Pineda, is a fine representative for his company. He was polite, respectful of both my husband and me, and took time at the start of the service call to go over what he would be doing and how he hoped to provide us with the best service we had ever had. He said that the goal of Comfort Energy was to provide us with service above and beyond expectations. He did not fail us. He even wore booties so that he did not track dirt into the house. My husband followed him around asking questions and he was patient and knowledgeable. Nasser also told us about their yearly service plan which would ensure service checkups before the heat of the summer and for the heater before winter cold months. That, plus the guarantee that we would get priority appointment times even during heavy demand, has clinched our participation. Nasser and Comfort Energy know how to do it right; ensure that the client doesn't want to go anywhere else for their HVAC service."

"On the weekend I called a few AC places recommended by Angie's List and HomeAdvisor, BAZ Service was the ONLY picked up the phone and made a suggestion to meet to repair the AC in an hour. Edmon and his assistance came and refilled the r22 Freon when it was emptied within 30 minutes. I checked the thermostat before, while and after Freon refilling, the temperature has dropped and the AC is cool again! Within an hour and serving on the phone and in person, I would strongly recommend BAZ Service per your AC repair needs. Thank you very much BAZ Service and Edmon, the AC is working and cooling the entire house again! :)"

"Alton was great and very knowledgeable. He was very patient and helpful. Hands down best hvac service in town. Marco was also very professional and punctual when arriving to the appointment. 5 stars!!"

"Alanis Air did a great job with my HVAC project. John Alanis answered all my questions and worked with me in deciding which system I should choose when replacing my very old system. His crew completed the work in one day, cleaned up the area and disposed of my old system. They were very efficient, knowledgeable and friendly. I would recommend Alanis Air for any of your HVAC needs! Thank you John, Santiago, Angel and Ismael :-)"

"Great job estimating HVAC requirements, as well as a smooth and detailed job with actual installation. John would consistently set up expectations on installation details, noise-levels, arrival and exit times, etc. He is highly professional, very detail-oriented about time taken and strict with timelines. Both my heating and AC work perfectly!"

"Air Sharks are very professional and I think they did a good job on installing HP HVAC in our property."
