Castle Heating & Air

When our furnace was nearing end-of-life, we reached out to Castle for quotes on a replacement, a heat pump, and a dual fuel system, with some redesign of our duct work in the furnace room. We really wanted to go with a heat pump, but due to some circumstances that are unique to our house, we decided to go with a gas furnace replacement. We didn't make a decision right away, and Richard would check in with us on occasion, but wasn't pushy at all. Then, when our furnace gave out completely (in the middle of a cold snap in December), he was able to revise our quote quickly. We took three other bids; Castle's was the best on price and we liked their maintenance program, which we plan on purchasing. We also appreciated the time taken with us to answer questions and commit to a timely install. Key to decision was their proposal to a required change in furnace configuration and redesign / alteration of the ductwork. Even though we were in the midst of the holiday season, Castle committed to get the job done before Christmas, and did just that. The install team was professional and efficient, and a pleasure to work with. Thank you!

Richard and his team installed a new heat pump system (heating and AC), and replaced all the under floor ducting in our San Rafael home. Richard and his team are great - professional, responsive, knowledgeable, fair, and friendly. Our system is performing as expected and we are very happy to have worked with the Castle team.

I cannot recommend Castle Heating & Air highly enough. Richard and his team just installed a 3-ton Bosch HVAC system, including brand new duct work with seven registers, compressor/heat pump, pad and attic-mounted air handler at my 1950-built house. They also installed a Mitsubishi ductless mini-split system in a part of the house where duct work could not be run. The entire job took a week, and work commenced within two business days of signing the quote. They couldn’t be more pleasant to work with and their workmanship was top notch. They also kept the entire house clean as they went, even when cutting holes in the ceiling for the air return and registers. Castle was the most competitive price I got from among five different companies as well, including Costco. I would hire them again without hesitation.
