Contra Costa

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. Service: Install AC

Recycling old air conditioning heating system and find out they moved love to find where they moved I like say they are a great company and good people are to be missed Billy carthen of Oakland ca.thank s you for the scarp mentel

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.

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. May 11, 2021 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.

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.

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.

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!

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.

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.
