Services Mini Split Installation & Repair

I am so thankful for everything Contra Costa Heating and Air did to help replace our heater and install central air in our house. Since we have an HOA, the process has been a little harder trying to get everything done exactly how the HOA wants things. However, since the beginning meeting with Tommy to talk through the details, we knew we were in good hands! Everyone from the company was extremely professional, polite, and helpful throughout the entire process. Even when I called the office they sounded generally happy to hear from me, which was so nice and made me feel valued. I would absolutely recommend this company for your air conditioning and heating needs! So professional, quick, great work, and everyone was so nice!!! 10/10!

Had an air conditioning unit installed and the service from the time we called to the finished installation was exceptional! Highly recommend Contra Costa Heating & Air Conditioning.

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.

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.

Fair pricing, no hidden surprises, very transparent.

Thank you so very much for the proactive, punctual, very effective, and professional service call today. The crew was friendly, informed, and thoroughly inspected my furnace and A/C installation. Contra Costa Heating is a terrific group to have as a home care resource.

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.

Took care of my AC and heating needs annually and when it broke they came and fixed it asap. And the tech and owner seem to be very professional and I recommend there services !!! The price and quality is worth it

The installation was clean, professional, and done with minimal disruption.

Their crew worked respectfully and kept the workspace tidy the entire time.

If you’re looking for reliable HVAC service, this is the place to go, five stars from me.

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

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

I highly recommend this company to anyone needing HVAC service.

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 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.

Great value for the money, I feel confident in the work they did.

The crew did an excellent job replacing the furnace and adding AC. They were on time, clean, friendly and very capable. The job was completed in two days with minimal disruption to our daily routine.

Great guys.

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.

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.

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.

Raji was very professional and informative. He took the time to actually explain HVAC system.

I had a great experience with Contra Costa Heating & AC. I was referred to them from Costco and they went above and beyond each step of the way. Tony came over to my house for an initial inspection and was very professional. I applaud the team at Contra Costa heating & AC!

Peter came on-site for initial diagnosis and subsequently for repair of A/C. He was very knowledgable, on time, and efficient in his work.
