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.

They answered all my questions and walked me through how the system works.

I highly recommend this company to anyone needing HVAC service.

Exceptional in every way!

Raji one of their Heating Consultants came by our house today to provide an estimate for Installing a Heatpump. He was extremely prepared, had researched the house upfront with rough understanding of what we already had in place before showing up. He reviewed our existing Gas Furnace, its age, our electrical and desired location for a potential new install. Unlike other sales folks I who have visited, he had a balanced view, not aggressively trying to sell us the most expensive option they could offer, he provided multiple options, listed the pros and cons, offering a pragmatic view towards which accounted for our existing infrastructure and budget. A helpful neighbor with your best in mind. Looking forward to work more with him and his team!

From the first phone call to the completed job, the service was outstanding. They arrived on time and treated our home with care.

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.

I received the result I hoped for, efficient heating and cooling, done right.

We recently purchased a 4,000 sq ft home in Novato,CA. Both the gas heating and air conditioning systems needed to be replaced and large sections of duct work needed to be replaced as well. We engaged Contra Costa HVAC to install (2) Lennox Elite EL296V gas furnaces and (2) Lennox 16 SEER Condensers. The installation team consisted of three very hard working, knowledgeable and highly skilled field service technicians. Alex was our team lead. Over a three day period, they disassembled and removed the old units and installed and tested the new systems. The quality of the workmanship really shows in the welds, alignments, configuration and aesthetic appearance of the wrapped and insulated units. We were pleased with the consideration given in adjusting air-flow to provide comfortable heat and cooling throughout the house. We would recommend the services of Contra Costa HVAC to others without reservations.

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.

Claudio was amazing, in educating us, explaining the best way to use our heating/AC minisplit system. He fixed everything and we're very pleased with his service.

Just had Heating and AC system installed. Great work, clean, punctual. System works great. Thank you CC HVAC.

Had a Lennox furnace installed 2 years ago and decided to add AC this year. Installation was done in 2 days and crew was very professional. We ran into a problem though since the AC water pump wasn't turned on properly so there was quite a bit of water damage to the 1st floor ceiling. I called and the next day the office arranged for someone to come out and take a look. Another crew was dispatched to inspect everything and fix the damaged drywall. Wasn't exactly the smooth experience I wanted but nevertheless I'm impressed that the company spared no expense in fixing the flaw and ensuring that we were happy with the results. I think how a company acts when things aren't perfect tells you a lot more than when the install is clean. Definitely would recommend these guys.

Had the best experience with CCH&AC! From start to finish they were extremely communicative, friendly and accommodating to all my requests regarding schedule. And on the day of install, it was the same. Not only did I have great commmunication with the office personnel but it was kept going with the qualified men who came out to perform the work. They kept me gave me an explanation of what they were doing throughout the whole process and never once did I question their skill. I'm sure they have lots of great installers, but I think I lucked out with the 2 most wonderful guys ever, Oscan and Jairo! They ran into a couple of obstacles and never got frustrated. On the contrary, they went into "let's-figure-this-out" mode and in no time they were on their way out the door after completing a perfect installation in under the anticipated amount of time anticipated to do the job - AND - with leaving not a trace of debris behind! I would HIGHLY recommend this company for many reasons, but since communication, quality-of-service, and cost are on the top of my list, I'd have to say you just can't go wrong with these guys! I'm very satisfied and admittedly I'm a "teency bit" hard to please...lol

Reliable, professional, and clean. They arrived on time and completed the work efficiently. We will definitely use them 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. David and Joyce Goldschmid

Very impressed with how organized and efficient the crew was. They respected our home and completed the job without any issues.

We had a behemoth of a heater from the 1950s and the thought of replacing felt like the biggest chore. Contra Costa came in and gave us a cleaner and more efficient system within a few hours. They got rid of the old beast and cleaned up behind themselves. Extremely professional, hard working and friendly crew. Special shout-out to Tony K who helped us out a ton. They also had great pricing options. I’ll choose them every time!! Thank you.

Great winter service experience. They inspected our heating system, made a small repair, and ensured everything was safe before leaving. They did the 18 point safety check. Used a carbon monoxide and gas leak machine.
