Love 3rd Gen, Devin and the team! They are knowledgeable, professional, kind, and generous. Highly recommend working with them!

I am so glad that I found 3rd Gen Heating & Cooling. The team is smaller so it felt so much more intentional and trustworthy. They pay such great attention to detail, in which they were able to meet my needs from design to execution. The quality of their work is top tier. I knew that I was in good hands from our first meeting. They were very prompt and responsive, so this gave me so much more confidence throughout the project. Highly recommend Devin and his team!

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.

Laura Palacios on 3rdGen Heating & Cooling

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.

Had the pleasure of working with Devin today on a commercial project in Danville.
As Hers rater I get to see lots of AC installations, this was one of the cleanest I’ve seen. This young man takes pride in his work and does great job.
Very pleasant to work with, professional and accommodating.
