HVAC reviews in Mountain View, California

I received many quotes and Calvey had the best priced and very friendly. I got my new heat pump installed and we love it,

I had Calvey come out for a second opinion, and I’m so glad I did. He was incredibly knowledgeable, took the time to explain everything clearly, and quickly identified the real issue with my system. Thanks to Calvey, my system is up and running again.

I was having problems with one of the ducks in our master bedroom as we weren't getting enough heat, but the rest of the house was solid. I called calvey heating repair and they were out very quickly, and the service technician I came to the house was very respectful and walk me through the process showing me pictures and everything in just about an hour later everything was working great wonderful customer service

Called Calvey when my furnace went out. From start to finish with their customer service to the tech that came out excellent service all the way around. And to top it off they are a family owned company even better !! Highly recommend Calvey

This company is awesome! From the appointment being scheduled, to the estimator to the install!

Very satisfied with Calvey Heating & Air and will use them for any future projects!

Calvey is a company in which industry best practices are sometimes not followed.

In 2021, Calvey installed a 4-ton, single stage Bryant suitcase unit on my property.

This unit has seen less than 20 hr, likely less than 10 hr of runtime in these 3 years. It has evidence of an electrical fire due to completely loose - not even snugged connections on the contactor which should have been torqued to 35 in-lbs.

In my case, this led to the failure of the contactor, which lit on fire and shorted out the 24v control coil, which killed my Nest thermostat before blowing the fuse in my furnace.

This would very likely have been prevented if Calvey had followed industry best practices, which are to use a clamp meter to measure LRA and FLA to ensure they match the LRA/FLA rating. Taking this measurement immediately after installation helps prevent this kind of failure.

Calvey also installed a Bryant Condensing furnace on my property a few years before installing the air conditioner. The condensate pump was not wired with the safety shut off, meaning when the pump (which has a 5-10 year expected service life) inevitably fails, it will likely cause a flood in my mechanical room. Calvey not only failed to install the necessary wiring for the safe operation of the condensing furnace, they also failed to correct this error when installing an air conditioner several years later.

Further, some Calvey techs informed me they use 5% silver phos-copper brazing filler. Industry best practices are to use 15% silver phos-copper brazing filler because it has better flow characteristics, and lower odds of cracking with vibration/thermal expansion. 5% brazing filler is also often associated with the practice of "crowning" a joint, wherein rather than flowing braze into the joint, a crown is applied around the joint with very minimal penetration. I have not experienced a failure due to this, it is still a poor practice.

Calvey did not follow industry best practices in the installation of my HVAC system. The electrical fire and subsequent damage to the entire 24v electrical system of my home, as well as the sub-optimal brazing alloy and improper condensate pump installation, I cannot in good conscience recommend this company for your next HVAC project.

Great after sales service!

Edith Watkins

Unfortunately we had a very bad experience with Ed, the owner of this business. We chose him with a high price tag to install our new wall furnace heater, assuming it would be the best service.

Once Ed took the money, that was IT. Heater didn’t work well afterwards. We called, left voicemails, and texted him many times, no answer at all. We thought something wrong with our phone, so we called him from our other phone. He picked up right away, saying he never got our other calls or texts, and he promised he would come to us that day or the next day. He never showed up. Then, same thing again, he blocked our second phone number, never responded to calls, voicemail or texts. Although he gave us 3 years warranty on his installation, he didn’t care to honor it.

Would never recommend him to anyone. Please be aware: once he gets your money, he will never answer you.

Excellent & fast service. Very professional!!! I would definitely recommend this business to anyone who is looking for professional & quality services.

Great HVAC system inspection service. Technician was knowledgeable and helpful.

The comfort at home improved incredibly after their swift and efficient system repair.

The cleaning completely changed the vibe here. I'd tell anyone to call them!

They were really careful and knew what they were doing. It's a true game-changer; my house feels great now!

Sophia Williams, one of the Expert Heating & Air Conditioning staff from Mountain View, California, was extremely friendly and honest in her interaction. In an astonishing efficiency, she soon identified the problem at hand, placed an order for the required repair parts, and installed them successfully the following day, with the cost still being reasonable.

It's nice to wake up to a cool house after all the work that was done last week. Focusing on the simple things has made a big difference. I honestly think you should go ahead and do it!

In the quiet hum of summer evenings, our AC has been a steadfast companion, all thanks to the meticulous care from our dedicated technician. Their preventive maintenance transformed our unit into a powerhouse of efficiency, providing consistent comfort. The attention to detail leaves us impressed, and our home stays refreshingly comfortable, regardless of the season's demands.

Woke up to an unusually warm house and knew I needed help. Called for an HVAC check, and they were at my door in less than an hour. The technician was friendly, explained everything clearly, and got my system back to peak performance. Truly impressed with their professionalism and quick response. Highly recommend for peace of mind!

When my air conditioning decided to stop working on the hottest afternoon, the technician arrived swiftly, restoring cool comfort in no time. Professional and courteous, they explained everything clearly. In less than an hour, my home felt like a haven again. Highly recommend their expertise!

Oliver’s knowledge was professional, he ID the issue quickly. Great job

I use this company for a refrigerator repair, and they were fantastic. They diagnosed the problem and ordered the parts and had them in within days. Is the technician Vladimir was excellent
