Richard and his crew did a great job. They did a good job explaing the pros and cons of the system and were very prompt in getting back to me.

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.

So happy I made the investment to upgrade my hvac with Richard! We had just bought our home and noticed there was something’s off with our air and heating system. Richard came out promptly and let us know of the issues and hazard our old Unit was causing. I know nothing about this but loved how he was able to explain it to me in a manner that was simple and easy for me To understand. we schedule for a new hvac system and ducting to improve airflow so that we can keep our house heated and cooled when needed. It’s been night and the day the difference we have seen and felt since upgrading our whole system! Now when I run my ac the house actually cools down evenly and the airflow is actually felt unlike how it Had been before we did the upgrade. In this cold December days I’ve been able To stay warm and keep my house toasty without the need of constant small space Heaters I was running almost all day. Yes, it was an investment but as a homeowner I’m so grateful for their professionalism, keeping their job site clean (I’m a bit of a clean freak lol) while Doing this mayor upgrade. We are now all able to be comfortable at Home and no more nagging from the kids about how cold the house is. I can be at home comfortably without worrying about what the weather is doing. I’m so glad we decided to go with them! the skill and quality of work is seen. I was worried about not being able to feel or see the results but oh it’s been a huge!! I can feel the upgrade to keeping our home at a constant temperature. This is the one upgrade I don’t regret investing in.

This review is one-year in the making. My apologies to Richard and his team for this delay. August 2024, Richard and his team replaced our aging heating system and added air-conditioning. After speaking with several other companies, Richard was hands down the guy to go with. All communications leading up to install was clear, accurate and on point. Since having our system over a year we've had no issues and enjoyed a warm cozy home during the winter and a cool place to relax on warmer days. Hands down, if you're looking for HVAC service please consider Castle Heating and Air, you wont be disappointed. Margaret Shepherd ~Petaluma

I am so glad I found Castle Heating!! We were having aircon issues, got a quote from a big company in the area, who told us we had to replace our entire system and tried to get us to book the following week. Richard came out after, looked at the system and told us the system is fine, could replace one part and to keep running it. He was so honest and helpful - I couldn't believe another company tried to sell us a 30k new system and he came out and found one small part we could replace. I would not go with anyone else but him. Saved us and I can't thank him more!!

When looking to replace my furnace, Richard, the owner of Castle Heating reached out to me with a clear offer to help. They came promptly and measured the house to be sure the correct furnace they quoted on would be the best. He offered sound advice on which brand was the best choice for me. In all our interactions, I was super-impressed with the professionalism and good customer care they provided. I ended up going with another company simply because of scheduling, but would not hesitate to recommend Richard and Castle Heating & Air. Get a quote! They were super competitive.
