    When our furnace was nearing end-of-life, we reached out to Castle for quotes on a replacement, a…read moreheat 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!

Their price was double of what other companies quoted, told me my compressor was broken & needed to be replaced. I called a different company for a second opinion. My compressor was FINE, it was simply the fan motor that needed to be replaced. The second company charged me half of what Castle charged, fixed the problem & didn't lie to me
