Get matched with top air conditioning pros in Discovery Bay, CA

"Smart Heating and Air Conditioning was very responsive and came out when we really needed them. We were without heat as our old furnace no longer worked and our AC was on its last leg. Mike came out to give us a quote which was the best out of three that we had. He went over all options with us and now we are very satisfied to have a new and efficient heating and AC system. They lived up to their name as well, by upgrading my thermostat to a WiFi one that added that SMART touch to my system."

"We chose repair of a very old air conditioning unit due to the cost of a new unit. It is working now but we have no guarantee of for how long. Global responded quickly and repaired the unit within hours."

"I m thrilled with David Mendoza, Shane, and the entire crew. The crew was professional, knowledgeable and fun to work with. For the first time in 25 years the entire house has a uniform temperature! They cleaned the house when finished! I have no reservations in recommending Perfect Star Heating and Air Conditioning and David Mendoza s team. Outstanding work."

"Our technician Jet came out and after diagnosing the problem he discussed what he found with us and also suggested some preventive maintenance procedures to save us from some future maintenance. After agreeing on work to be done Jet took care of the necessary repairs and now the air conditioning is working perfectly. We were very pleased with the professional and honest work performed and will definitely be calling Huft Heating and Air Conditioning for any future repairs."

"I was fortunate to receive service on the same day I called. My issue was difficult to diagnose, as many have tried before. They were willing to step in and try to resolve my issue for good. They were successful at their first attempt. I am grateful to Guerrero Heating & Air this Labor Day weekend of 100*F+ weather."

"Jaleen from Albert Nahmans is top notch , diagnosed the issue with an old furnace , fixed it and made recommendations for repairs and or replacement . A huge thank you!!"

"I found Jim's Air Systems through HomeAdvisor, and Josh was the first contractor to reach out to me personally, not through an automated service. From the start, communication with him was excellent. I provided him with a detailed description of the job, along with model numbers and photos of my existing system. He reviewed everything carefully rather than giving me a quick, generic quote. I received another bid for comparison, but the other contractor was significantly more expensive and wanted to upsell me. It was refreshing that Josh understood I had done my research, knew what I wanted, and didn't pressure me into unnecessary upgrades. Josh's team arrived on time, completed the work as scheduled, obtained the required permit, and left my home as clean as they found it. Overall, a great experience and a solid value. I wouldn't hesitate to recommend them."

"Truthfully, we had angst about calling for service because of past experience with other HVAC vendors. They always said the same thing, our system is "old" and we need a new one. Very expensive! We called for service, not a hard sell! Hence, we never used the same one twice. However, Tyndall gave me the impression, whether right or wrong, that they would be less likely to do this so I decided to try them. They kept me informed of their arrival status, since they squeezed me in at the end of their work day the same day I called. So, communicative and accommodating! After running several tests, they determined it was an electrical problem and nothing to do with the unit itself. They also said our unit doesn't need replacing - that's a first! They didn't do any unnecessary service or repair to run up the bill or even try to convince us it was needed. We were only charged the minimum fee as quoted. We were able to repair our air conditioning without the "hard-sell angst". So, thorough and honest! Unlike the other HVAC vendors we've used, we definitely will call them if we need service again!"
