Reviews of local pros in Berkeley, California

Their service is great! We were having problems with our furnace. Adrian got us taken care of fast and our furnace was working better than ever. 10/10 highly recommended.

3rd Gen is very responsive when it came to getting them out to service our commercial HVAC system. Very reasonable pricing and superior customer service. Their staff goes above and beyond to explain the issue and the results of repair. Have called them twice already and have always gotten a quick response and a fast turnaround on repairs. Will definitely recommend this company to family, friends and businesses for referral.

Thanks for the heat pump install. Very professional and would recommend

They rock. Super responsive. Office staff fantastic on the phone. Tech was awesome and knowledgeable. They helped when no one else would or could. I’d recommend anytime.

Feeling relieved to have found a reliable HVAC company willing and able to keep up with the demand of our rental properties. They are efficient in making appointments with our tenants and always keep us posted - their billing system is nice too. It's been really cold recently and we've been working with them on several projects. They have been very easy to work with. I'm impressed.

We were in need of an AC and called around for a few estimates. This was the only company that we felt was honest with their estimate, and provided quality work. They were on time, thorough with their work and friendly as well! Highly recommend them to anyone else who needs an AC installed!

“3rd Gen HVAC is top-notch!
Devin and his team were incredibly professional and efficient.
They quickly diagnosed and resolved our heating issues.
Highly recommend!”

This was the first time using 3rd Gen, and will not be the last. The technicians that came to my property, Devin and Ramon were amazing. They were able to complete all scheduled repairs the same day, and even stayed late on a Friday to get them done. Also, they did all the repairs without any inconvenience to my residents. I have more repairs scheduled and look forward to the same incomparable customer service we received before.

Devin and his crew did a fantastic job to install AC for our whole house.

Highlights:
- They only use high quality appliances from Mitsubishi
- Clean installation
- Helped us with a broken AC unit for our shed without extra cost

Third Gen Heat Pump was one of the more pleasurable experiences I’ve had in a while. They were the first one to call me back and the first one to show up. They called me 15 min prior to arrival and my broken heater was diagnosed and fixed within 10 minutes. A definite recommendation for anyone.

This is our 2nd time using 3rd Gen and we could not recommend them enough. Their team is friendly, efficient and very professional. I appreciate their punctuality and willingness to help us understand the problem and how to take care of the items they installed. We had our heater replaced and a/c re-installed this past year and both were very pleasant experiences from start to finish and not to mention their fair pricing. Both ac and heater are functioning perfectly now. Thank you 3rd Gen!

I did not know much about mini splits but now I certainly do. Devin is absolutely amazing. Not only is he very reasonably priced, he is meticulous, methodical and knowledgeable. He and his crew traveled all the way to Modesto to install two mini-splits in my duplex. He even explained things along the way. He was patient and makes certain that the customer is satisfied. Excellent work ethic, professionalism and right on time. Highly recommend 3rdGen Heating and Cooling!

Yesterday we had a Mitsubishi mini-split unit installed by Devin, Will, and Chris (electrician). I must say that the work was done in outstanding fashion. Both the indoor and outdoor units were installed with care and communication with us. I don't think the job could have been done any better. Needless to say, I'm a very happy customer. Plus, I can get about a $2500 federal tax credit because of the high efficiency of the system.

Highly recommend. Talked to the owner directly and he was very knowledgeable and genuine, something hard to find these days. I was very pleased with the installation they did for my inlaws. They switched from gas to a all electric system. They were even able to get a tax credit from doing so. 10/10 highly recommend

Devin was AMAZING!! He came same day to fix my unit and gave me honest pricing to fix my issue. He told me what the problem was and also showed me so I understood. He got my AC up and running within 30 minutes. I will exclusively use 3rdGen going forward

We call Devin at 3rd Gen Heating & Cooling for our HVAC service needs - replaced the blown fuses in my Mitsubishi minisplit due to an unexpected power surge

The work was done in a timely fashion and for a great price.
Devin and Cesar were incredibly helpful, and worked around some intense weather to get our heat pump and mini splits installed.
Thank you!

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.

3rdGen recently replaced a commercial roof HVAC unit for us at a building in downtown Danville. The entire process was a breeze as they handled the crane operation, the permitting, and the testing. Both us (the owners) and the tenants were very pleased with their service and attention to detail.

Was able to get a same day appointment for my 2 service requests. Technician was nice, quick, and answered all my questions. The technician identified the issue quickly and was able to get everything done in less than an hour. Scheduling was easy, and was able to charge my payment with a card. Invoices were emailed. Will recommend to others.

They installed a 5 phone Mitsubishi mini split in my home. The guys always cleaned up and did a good job. Thank you Cesar, Devin, and Juan.
