Tech Air

We’re very happy with Tech Air and would highly recommend them! They installed a new furnace and heat pump for us, and they were so good we brought them back another time to do more work on our ducts. They were transparent and fair in pricing, and answered all of our questions. The crew was always friendly, considerate, and left the job site clean each day. They also organized the work in a way that minimized disruption to our system; they never left us without heat! Very happy with our new system and would work with them again.

We replaced our old gas heater with a new electric heat pump and air handler system, and choosing Tech Air was absolutely the right decision. From the start, Colin was thorough, attentive, and generous with his time—clearly explaining the process and demonstrating a strong understanding of local building codes (which can be especially baffling in San Anselmo). The project began and ended exactly as scheduled, and Colin and his crew were consistently clean, punctual, communicative, and respectful. After the installation, we unexpectedly experienced electrical issues—dimming lights and non-functioning outlets. Colin came over right away, identified a problem with our electrical panel, and fixed it promptly. The issue may have existed prior to Tech Air’s work, but Colin figured out what was

Tech Air came highly recommended to us by our friends. They definitely exceeded expectations. Our HVAC system was over 30 years old and needed replacing. We also had issues with our ducting. I reached out to a lot of companies - Tech Air had the best communication and pricing. Colin and his team did a great job!! Our new HVAC system works great so far. It was installed with much detail. You can tell this company takes pride in their work. They were also very clean which I appreciate. Our home was left cleaner than before they started. Our project was also completed on time and the entire team communicated with us throughout the process. We had a very positive experience with Tech Air and will definitely use them again in the future.

Outstanding Experience with Tech Air! From start to finish, working with Tech Air was an absolute pleasure. Colin, the owner, was incredibly communicative and took the time to truly listen to all my requests. He designed an HVAC system to my exact specifications — no shortcuts, no upselling, just thoughtful recommendations and expert execution. Their pricing was very competitive, especially given the level of detail and craftsmanship. The team removed my old gas furnace and installed a new 5-ton heat pump and air handler, even adding a new cold air return downstairs to improve overall performance. They also removed the old duct insulation, sealed, taped, and rewrapped the entire system with new insulation, ensuring everything was airtight and efficient. Colin and his crew are the defini

I have been doing HERS verifications for Tech Air for probably 6 years. Always a pleasure working with Colin and his team. They are the top dogs in Marin County!!!
