Tech Air

Colin Hallat and his crew did a phenomenal job removing our gas furnace. They installed an electric heat pump and filed for rebates, as part of our plan to transition from gas to electricity and solar. The job was timely, clean and professional. I highly recommend their services.

I am highly satisfied with the service received. The price they quoted was very competitive and provided the best-rated equipment in the market. Both the management and the technical people were very friendly and outstanding. They handled a challenging connection problem specific to the building and met strict HOA requirements. My background is in engineering, and I recommend this company very highly for its technical competence, professionalism, and friendliness.

Colin Hallat of Tech Air was very professional in the presentation of his proposal for a heat pump/AC unit and new vent/duct installation in our home. His crew worked efficiently and finished the job on time. Colin was very responsive to all phone calls and never tired of answering our questions about the heat pump technology. We highly recommend Tech Air for your HVAC needs.

Tech Air did a great job replacing aging furnaces and installing heat pumps. Really appreciated their follow-up on and resolution of small issues that popped up related to my particular installation. Would definitely recommend.

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 was very responsive and easy to schedule working around complications of my own schedule. He was also very knowledgeable and quickly fixed my heating system with a very fair cost and value. He will be my first call for any additional heating and air issues.

100% professional experience from start to finish. Quality technicians and installers, excellent communication and good people to work with. Everyone in the organization. Highly recommended.

Colin and his crew replaced our central air furnace with a new outdoor heat pump, indoor air handler and a mini-split in a previously unconditioned master bedroom. Their crew was prompt, tidy and did a great job on the install. Highly recommended!

Hired Colin and his team to do replace our old furnace. His team did a great, very professional and good workmanship. All at a fair price. Thank you!

Tech Air, Colin and his team, are extremely professional, and replaced our 30 year old furnace and added Air Conditioning. Tech Air takes pride in their work, and I highly recommend them to anyone interested in getting knowledgeable advise, competitive pricing, along with quality and professional heating and air conditioning work to contact and use Tech Air
