HVAC reviews in Pleasanton, California

This repair company has the best technician and offers the most affordable air and heating repairs in town. I’m so glad I hired them because they handled everything expertly and left me completely impressed.

Our HVAC maintenance was thorough, tech cleaned and inspected the system, works like new. THANKS

I am glad I found this team. The technician fixed my heating and cooling system without any hassle and had everything back to normal fast. You can tell they are precise with their work. Got it all done in under an hour. Really appreciate that kind of service. Thanks a lot!

This company gave me one of the best service experiences I’ve had with AC and furnace repairs. The technician put in real effort, got the job done right, and the price was more than fair. I’ll definitely be telling others about them.

A concerning heater noise was fixed during a maintenance check. The team quickly resolved a loose blower part. The rattling is now gone, efficiently restoring quiet operation.

Before‍‌‍‍‌‍‌‍‍‌ the winter season, I was not sure how to maintain the furnace in good condition so I asked a technician for some advice. The whole staff was very thorough in their inspection and they even tested the unit to confirm it was operating efficiently. I am now feeling very comfortable and confident that I will be able to brave the cold ‍‌‍‍‌‍‌‍‍‌season.

I got a consultation from Raji, he is very knowledgeable, professional and friendly

Two thumbs up to Peter and the team at Contra Costa HVAC! They found my issue and fixed it the same day! I really appreciate their attention to detail, when Peter came to my home, he had his protective gear on and was ready to work. This is a team I can trust and rely on, I will be calling on you again!

We recently had a new Lennox furnace and air conditioner installed. Despite some challenging issues relating to the layout of our home, where access to power and the furnace are not easy, they were able to overcome each challenge one by one. We now have a well functioning system that works and looks terrific and much better than we expected. They have a hard working crew tolerant of endless questions, and very creative problem solvers. They came to the house on time, finished on time and on budget. Thanks to Julie for helping with financial stuff, Gilbert for super workmanship, and Tommy for his patience and design. We can recommend this company highly.

It all started with Tommy Rojas the sales person. He is very pleasant to work with and not 'pushy' at all. He listened and offered cost-effective plans that included quality equipment that fit our budget. After we agreed on type of equipment Tommy arranged the rest of the work flow from arranging for the duct removal (asbestos) to installing the new ducts and equipment.

Next was Alex and his team who did the actual work of installing the ducts and equipment. Alex and his crew were very respectful and made sure to keep clean our flooring as they proceeded to remove the old equipment and install the new HVAC. They went beyond expectations because they did small repairs not necessary to the HVAC replacement, they cared about fixing small things such as the door to the HVAC closet and provided extra air filters. Once HVAC installation was completed and functionally tested, Alex made sure to explain the operation of the new thermostat, equipment and answered all our questions.

We are extremely pleased and highly recommend the services of Contra Costa Heating & Air Conditioning. Big thumbs up to Tommy, Alex and his team!!

I highly recommend this company to anyone needing HVAC service.

We had an air conditioning installation today by Contra Costa Heating and Air Conditioning and the experience was fantastic!

They sent two crews and got the entire installation and system check completed in just six hours.

Every part of our experience from site visit, estimate and installation was professional, touch less, and current covid-19 aware.

Awesome Job, we should have done this 10 years ago.

Company has a habit of spamming people in hopes of selling them questionable deals.

Excellent service from start to finish, very attentive and professional crew.

It is getting close to 2 months now and the contra costa team has done nothing regarding the inspection feedback. They made an error when they applied for the permit but they are making no effort to fix that and close out the issue. They have not been communicative either and I am tired of reaching out to them. This was through Costco and I had hoped for better service and this has been disappointing and a waste of time.

Manny and Fausto did an amazing job replacing a new heater and ac unit at my house. They were extremely polite and professional. They explained me everything they were doing. When done Manny explained the whole unit all the bells and whistles. Showed me how to operate the new touch screen thermostat. In all I'm extremely satisfied with the work and the professionalism that Manny and Fausto did on our unit. They were very mindful on how they worked in our home as if they were working on their own home or a family members home. I will definitely be recommending these great guys. Thank you for the great service fellas it is much appreciated.

Had such a positive experience with the installation of my new Lennox heating and air conditioning systems. It started off with the lead introducing himself, Danny, and his co-workers, Fausto and Abdul. They were all extremely professional and respectful of my property and cleaned up daily when they left the job. They are also very hard workers, never taking breaks except for lunch. Danny was extremely knowledgeable on the products and very patient in explaining the workings to me. I would not hesitate to recommend Contra Costa Heating and Air Conditioning to any of my neighbors facing the prospect of replacing their systems too. Kudos to Danny for making this experience so easy and positive! Thank you.

Manny and his crew were amazing. We bought our house August of 2021. The 4th time we turned on our heat, it blew carbon monoxide all throughout our house. The people who we bought the house from and the owners before them who renovated the house, lied to us and the heating never worked and could have killed us. We called in Manny and his crew for this serious situation and they are the most knowledgeable at their trade. They were able to figure out exactly what the original installers did wrong, and what the previous owners guys did wrong trying to bandaid the problem. You can trust Contra Costa 100%. They are the right team for any problems you’re facing with heating and air systems. I now have a new system that works perfectly and I am so grateful to them.

They were sent by Costco, the representative came by and gave us a quote to install a new Heat Pump and Furnace. We had also discussed that all duct lining and the line set needs to be changed as per the new specifications for the new unit. He sent a quote that evening, when I initially read it it was missing 2 ducts and no mention on changing the line set. So I called the next day and left him a voicemail that he needs to update the quote to the agreed upon terms. Later that evening when I checked to see if there was an update the quote was not accessable. I called the representative and told him that I was not able to access the quote and his answer was "when prices get changed the quotes are not available" and hung up. All we had asked was for him to update it to the agreed upon terms.

I gave a rating of 1 star back in May for the reasons explained below. The firm president Anthony contacted me and apologized for Operation Manager Teo's unacceptable email. There have been a few technical problems since then, but support by lead technician Pete and Marlo has been very good. They came out and fixed the zoning (loose wire connection) once. Late the cooling was weak, but Pete came out and fixed the problem. The system is working well now. Because of the continued responsive support, I increased my rating.

I signed contract with them 10/1/20 (over 6 month ago) to add AC and replace a furnace. The AC is still not operational. A zone control board was responsible for part of the delay. They cancelled on me last minute last week because of other jobs. Maybe they will finish tomorrow. We'll see. I could put up with the delays if they did a top notch job. Sloppy roof penetration led to rain leaking into our attic in January. I was patient with them for a long time. I have been trying to stay positive about this firm, but today I gave into reality and have accepted that I picked the wrong shop. Sales rep Henry was nice enough. The technicians seem to work hard, but are not allocated enough time to finish the job. Operations Manager Teo Seeger is generally unresponsive. He finally responded today to an email regarding a concern I had about the condenser unit placement. He did not answer my question. He only wrote, "This is installed 100% to code". Code is the minimum requirement and was not my question, but maybe that's the best he or his shop can do - code compliant. I cannot recommend this firm to anyone.

The technicians arrived on time and worked efficiently, leaving everything spotless.
