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!

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.

These guys are awesome! I was working with H-Squared Mechanical from South Bay Area who was the initial HVAC company who installed all our Heat/AC for our brand new property. They screwed up big time at our property it was to the point we were paying $6K per visit and they still didnt fix the issue. I then reached out to Contra Costa for help and they fixed all the issue we had. And the main issue was just wiring! Pete from Contra Costa is great! We love working with him. Hes on time and gives great advice about the AC and Heat. I recommended Contra Costa to all the sister sites I have in the area.
