Best Heating & Air Conditioning / HVAC In Berkeley

“Great service. They fixed my old ac unit with one visit. Very knowledgeable and professional.“

“I got my HVAC system installed by 3rd gen in 2022, this week the heater stopped working . I gave them a call and Devin and Ceaser visited today to fix the issue. They were at the house right at the appointment time, understood the issue and fixed in few minutes. I found them very knowledgeable and friendly. They explained in detail the cause and how to prevent it in future . The best part was they were so nice they didn’t charge me as it was not a major fix. I always recommend 3rd gen for an awesome professional experience. It was a very good decision to purchase my HVAC from 3rd Gen.“

“Great job. Arriv d within window of time. To the point. Very nice. Kruse Plumbing great as always.“

“I always ask for Stormy. Another outfit wanted to sell me not one but two new water heaters. Stormy ordered a small part and fixed the problem expeditiously. He also forecast another 10 years for the two heaters (system) we have in place. Knowledgable, trustworthy, thoughtful and friendly. Highest recommendation.“

“I had such a great experience working with Cooper & Hawkins. They did an excellent job and everyone was so friendly. If you want an quality, easy and stress free experiance this is the company for you.“

“Great service and nice to work with! Thanks for getting us back on track! :) It's also nice to work with a local business.“

“If I ever need HVAC equipment again, I will definitely be buying it from them. I had a boot that needed to be replaced and none of the hvac stores around me or online carry it. I described the piece I needed and they fabricated it quickly. Thank you Berkeley!“

“The blower motor broke on my Carrier Infinity furnace and they were able to get the motor the next day in Concord and changed the unit for me in Oakland. It was also covered under warranty even though they did not do the initial installation. When it comes time to change the unit I would use them.“

“Chris and his crew were great to work with. Very professional and the work was well done. I was very impressed with his attention to detail and how fast everything came together. He responded to my texts quickly, was able to work me into his schedule the same week and finished a day early. Overall I am very pleased with the work and will call again when I have future projects. Thanks again Chris!!“
