Climate Masters may be the best HVAC company in town, especially for old houses or anything complicated. They are stable, still the original ownership, lead installer has been there for a long time, union shop. Several neighbors have used them forever. They are expensive, but use good equipment, are eminently competent, smart, organized, agile, easy to work with, and they don't nickel-and-dime. We had them replace our central AC/furnace, which involved navigating expected and unexpected old house stuff, and fixing pre-existing issues along the way. I'm finicky, and both the owner and installer were good sports and willing to accommodate. Installation went smoothly, everything seems to be working fine, and the new system looks great and gets admiring comments from other trades and professionals.

I had a great experience working with all of the staff at Climate Masters. Making a large purchase is never a fun experience but I felt at ease with this inevitable decision because they talked me through my options, were helpful and available, and provided flexible financing options. I’ve already recommended climate masters to my friends and now to you!

Using Climate Masters was far and away one of the best decisions we've ever made as homeowners. Their attention to detail is excellent. Not only did they install a new furnace and air conditioner; they corrected ductwork that had been undersized for our home. The installation crew was friendly, courteous, and did a great job cleaning up when all the work was done. An absolute five star experience.

We needed a new a/c unit and after calling several places, their customer service was without question the best, their price was reasonable, and their installation was timely. They are now our first call for any HVAC issues. Can’t recommend this small family owned business enough to anyone in the area!

We have used Climate Masters for over 25 years. They put the entire HVAC system including ductwork in our century home 25 years ago and just replaced an older system in our current home. They are friendly and very knowledgeable. We highly recommend Climate Masters. .

Doug and his entire team go above and beyond to take care of their customers! Our unit went out during a 95 degree heat wave and they were out at our house by 7am the next business day and we had a quote with a solution ready for us by 9am. The team installing our new unit was incredibly efficient, kind and considerate. But the most important part I want to note is that Climate Masters saved us thousands of dollars. Another company we had called first quoted us 40% more than what Climate Masters was able to give us and their team was 100x nicer and more focused on customer service and support than the other company. We can't recommend Climate Masters enough!

Tom and his crews are the best. They do excellent work and respond promptly. We have used them twice for HVAC systems (one upstairs and one downstairs) and they are good people to work with.

5 Stars! We've been happy Climate Master customers for 25 years. They installed an HVAC system and ductwork in our 100+ year-old house when we moved in 25 years ago. They replaced the original boiler with a new energy-efficient model. They've kept us cool and warm for 25 years, always there when we have a question or problem. Climate Masters just installed a new HVAC system, replacing the 25-year-old equipment they gently nursed along for so many years. We trust Climate Masters!

The team at Climate Masters helped us get a a complete HVAC replacement when our 22 year old system went out. We had an existing maintenance agreement with them and the entire team from the technician to the owner who came out as well helped us work through the process of choosing what HVAC was going to be right for us and our home. Their schedules were tight as our AC went out during a heat wave and they were kind enough to put in 2 AC window units to get us through the few days with no AC. The installation technicians were top notch: communicated well, were quick and throughly cleaned the area leaving it cleaner than it was before they were there. Would highly recommend.
