Reviews of local pros in Corte Madera, California

Great system and great price! Big thanks to Colin and his team for installing our new heat pump.

I recently had Tech Air install a new heat pump system in my home, and I couldn’t be happier with the experience. From start to finish, they were professional and friendly. The crew arrived on time, worked efficiently, and took the time to explain the installation process and answer any questions I had.

Their attention to detail was impressive, and the quality of their work shows. The heat pump system is so much quieter and efficient than my old furnace, and the ability to both heat and cool seamlessly has been a game-changer for our family with young children.

I highly recommend Colin and his team at Tech Air. I am confident they will do a great job for you!

Colin and his team were extremely professional. All their work was explained well prior to the process, and everything went faster than I expected. I cannot express how grateful we are to Colin for making the process quick and easy. Thank you!

I don't typically leave reviews, but I felt compelled to share my positive experience. When getting quotes for our new mini-split system (replacing an old furnace and AC), their quote was one of the best we found. What truly stood out, though, was the professionalism of the crew—they maintained a remarkably clean workspace and were incredibly responsive throughout the entire installation. Colin's commitment to transparent pricing upfront really built trust and made the decision easy. This kind of service is rare and absolutely worth recommending!

Colin at Tech Air was a tremendous help and highly professional when I was in a jam with a HVAC emergency over the weekend. I would recommend Tech Air to anyone!

Colin and his team were amazing to work with. We first had Colin over to get us a quote, and it came in more than competitive with the other contractors. Given he's a certified Mitsubishi installer, I felt I was getting a great price, warranty, and equipment.

Installation date was set, and my old existing furnace started getting worse, banging and clunking -- he was so kind to offer to help me diagnose the issue and even offered to help me keep it running at no extra cost until the new system was available to install.

The installers were very professional, they kept the areas immaculate where they worked, were very polite, and were happy to work with me to get me what I wanted, vs doing the easy quick way on many occasions.

I ended up with a five cassette heat pump system, and am very happy with it. When I needed some fine tuning on operation for it, Colin didn't hesitate to come back and the tweaks for me.

I'd recommend Colin to anyone looking for a fair, honest, customer-service oriented install and equipment.

We received several quotes for a Trane AC system with ducts before finding Colin and Tech Air in Mill Valley. Colin and his team are genuine and fair, and take immense pride in their work. They worked efficiently and set clear expectations, informing and including us in any major decisions to be made. For the one modification required, they only charged us the cost of the additional part, but not anything more and even patched some unrelated dry wall for free. When the project was completed, they returned to ensure the system was operating and our inspection was approved. We highly recommend them for their exceptional service, professionalism, and friendly local feel.

Colin at Tech Air is top notch. He installed a complex, high-end Mitsubishi mini split system with seven heads in our 110+ year old four-story Edwardian in San Francisco, with all the challenges of lath and plaster walls, and did an impeccable job. Fair price, excellent communication, and real thoughtfulness in every detail. Colin is a total pro—highly recommend.

The Total experience with Tech Air was great. From the first visit to determine a price to the installation of a new heating unit i could not be more pleased. Courteous, neat and professional describes the project.

Colin and his crew did a good job replacing our 3 furnaces with heat pumps, and had the best price of the 4 quotes I got. Colin was responsive, straight forward, and didn't do any hard selling.

Colin and his team at Tech Air did an excellent job installing my Mitsubishi heat pump unit. Installation was efficient, tidy and professional; pricing was fair. Colin was able to provide key insight regarding asbestos, information that was very relevant. Paperwork and permitting were accurate and timely due to Claudia's efforts. Recommend highly!

Colin and his team worked fast and efficiently to install our heat pump. He had the most competitive bid and was super responsive and easy to work with. Would recommend him all day!

Can’t say enough good things about Colin. We had 2 other companies come out to diagnose and give estimates for repair prior to calling Colin. One was uncertain of what was wrong. The other gave a quote for $475 for a capacitor. Colin arrived and checked it over and found a single clipped wired that needed to be reconnected. Tech Air is Super professional and honest. Highly recommend!

Colin and his team were great to work with! I really appreciated Colin’s expertise and great explanation of our options. I felt confident going with him right from the beginning. His crew delivered excellent quality and really paid attention to all the little details. So not only did it work well but it looked great as well. Colin’s prices were on par with every other company we’d gotten quotes from and we’ve been happy (and cool!) with the results ever since.

I highly recommend Tech Air. Colin has serviced our furnace a couple of times and is reliable and honest, providing us with multiple options for when we need to replace our existing system, but not pushing us to change things while the system still works. When the time is right, we will without a doubt use Tech Air to replace our HVAC system.

Our experience with Colin and Tech Air could not have been smoother or more pleasant. It was a challenging job, locating a condenser under our deck and two mini-split head units on opposite sides of our hillside home in Tam Valley,

Tech Air is everything you could want in a Marin contractor: they’re service-intensive, knowledgeable, collaborative, considerate and professional. They represent top-of-the-line products and employ caring and efficient installers.

At the project's outset, Colin sat down with us and patiently listened to our design priorities and scheduling needs, and then showed us how Tech Air could meet our wishes. At project's end, our county inspection was a non-event, as the inspector signed off on the installation without needing to call out any corrections or revisions.

With Tech Air, Colin has put together a really impressive outfit that provides superb service. We're so glad our neighbor recommended Tech Air.

I had a great experience with Tech Air. Collin was very quick to respond to my repair request (he came the same day) and was very flexible; he worked with my complicated schedule! He identified the problem with my furnace, fixed it on the spot and came back the next morning to replace the thermostat. He was extremely efficient, professional and friendly. I would definitely recommend his services.

I called Collin when we were having an issue with our furnace, and he came out the very next day. He then completed the job the following day. He’s extremely experienced and has a great work ethic, and his associate was also super helpful. They showed up promptly and completed the job in record time. I would absolutely recommend them to anyone.

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!!!

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 definition of a small business that takes tremendous pride in their work. They showed up on time every day, worked efficiently, kept the workspace clean, and completed the job right on schedule. Their professionalism and attention to detail really stood out.

A special shoutout to Claudia, who handled all the paperwork, scheduled the inspection, and made sure everything was squared away for warranty and compliance — she made the entire process seamless.

I couldn’t be happier with the results. If you’re looking for a trustworthy, high-quality HVAC company that genuinely cares about its customers, Tech Air is the one to call.

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.
