I wish I had written down the name of the operator who scheduled my appointment but she was polite, professional, and courteous. She went above and beyond to find an appointment that worked with my schedule. She called back as promised and I was never left hanging or waiting for information. 5 stars for the operator, thank you! My technician was Victor who arrived during the scheduled time window. He was very knowledgable about the HVAC systems used for the homes in my neighborhood. He was able to quickly confirm the issue, diagnose the problem, and find a solution. He then performed a series of tests to confirm the issue had been solved. During each step of the process he explained what was happening in a way that was easy to understand. I now have a much better idea of what my system is doing and how it operates. 5 stars for Victor and I'm grateful for his service.

Disappointed after reading the reviews. These guys are in the same town. I figured I'd give them a…read moretry for installing an adding a mini split addition to supplement hot/cold spots in my kitchen. Not only did they not listen to my needs, the whole time they offered solutions that cater to what they want instead of what I want. 1. They recommend dual zoning which cost about the same amount as installing a new mini split. I have a single state HVAC which isn't recommended for dual zone install. 2. They keep pushing for fixing/upgrading central instead of installing mini splits. 3. They keep asking for my budget (red flag), talking up high end units (red flag), talking down low end units (red flag). Look, we all know Mitsubishi and Daikin are the top of the line. However, the cost of DOUBLE of the price of lower end models isn't due to just superior quality and technology. Heat pumps and mini splits are not new technology. One isn't vastly superior to another. Yes, it may be better, but not double the price better. The cost are always due to the commissions and kickbacks for these installers. That's marketing and salesmanship, but please be more transparent next time. Finally, I asked for quotes and options so I can decide. The person walked away disappointed and I suspect they think they lost a sale because of the way I did not want the highest end models and stayed firm with my mini split request. I sensed the guy walked away disappointed. Yet I still expected a courtesy quote like the other installers. They never sent it. I was not surprised. In the end, I decided that a whole system upgrade to mini-splits (30% more efficient just from being ductless alone) with rebates made more sense instead of add ons to existing system. But these guys did help me cross them off the list and went with the installer who actually listened to my needs and gave the recommendation and options that I wanted. I do not recommend these guys. They will push for the highest cost system and will ghost you if you appear to be knowledgeable enough to call them out on it.

Years ago the apartment complex I lived at contracted Calvey to install mini-split A/C in the…read moreapartment I was in. The install was amazing quality! So much so that it gave me the confidence to buy my first home without A/C because I knew I could just call Calvey. A few years later I did just that. Damn, it's been a couple of months now and I've been able to control the climate of my entire house from my phone, optimizing the temperature and sometimes making it as low as 66F to just enjoy the air being crisp. The install has been fantastic quality and the crew listened to everything I wanted every step of the way. They mounted rat spikes where I wanted, they put the lines and the units exactly where I asked and I've had no issues at all. I truly believe with home price comparisons in my area that I made money off of the install because it increased my home value. My golden retriever is happy, I am 100% happy and I will see you guys again next home upgrade. :)

Three years ago we found a different company that was able to address an ongoing problem that Calvey was not able to fix in over 4 years time and after spending much money over it. Since our move away from Calvey, we keep finding errors in their work and workmanship.

Shoutout to Salvador Leyla and his associates at A1 Heating and Cooling. In 2021 A-1 (led by Juan…read moreLara at the time) installed for me two Trane 3 Ton Air Conditioner Condenser units and two 2 Trane Effects HEPA filters, plus a new furnace to replace one of my furnaces - at my home in Los Altos. I also purchased at that time a five year maintenance plan such that A! would come visit my house every six months for tuneups and maintenance - which they have dutifull done ever six months for the past 5 years/ There tuneups have been extensive and comprehensive. I have recently extended that maintenance plan to 2031. The A1 team is *extremely* professional and also very knowledgeable. During their most recent maintenance visit (April 2026), the A1 team led by Sal Leyla diagnosed a small shortfall in the refrigerant levels in the two Trane units and because of me having pre-paid A1 for semi annual maintenance visits, they not only were able to quickly add refrigerant but the cost to me was very affordable. I should also note that based on the professionalism displayed by the A1 Team back in 2021, five of my neighbors also hired A1 to install air conditioning units. And they are all very happy customers. A1 is an excellent company to work with in all respects and shoutout to Juan and Sal for their professionalism and great work. I'm happy to serve as a reference for A1 and also happy to talk by phone with anyone who wants more details. ---Mark B c - 650 520 9026

They helped educate me about the various options available for my house, explaining the pros and cons, and exploring solutions for the temperature imbalances I have in the various rooms. Their price estimates were very reasonable, with detailed breakdowns of options I can choose. I ended up having them replace my 50-year-old asbestos ductwork (with permits), and install for me a heat pump in dual-fuel configuration, so that we can have energy efficiency most of the time, but still get toasty gas heat in the winter. They never tried to upsell me, and the heat pump we chose is cost-effective and quiet, while being more than enough for my home. The work itself was carried out efficiently and respectfully, with a lot of attention to detail, and finished ahead of schedule. In addition to the 10 year equipment and 3 year labor warranty, they offered 1 year of free maintenance. After the install, they have continued to be very responsive, returning several times to help rebalance and optimize airflow between the rooms, and to troubleshoot and fix any remaining noise issues. They've really put in the effort and ingenuity to solve my HVAC problems!
