We had Chris come in for an HVAC inspection for a real estate transaction; he was very detailed, explained everything... thoroughly, and very honest. Stacy was also very helpful in communicating/answering questions and getting us the report back in a timely manner to meet our deadlines. Highly recommend the Connolly team to any realtors looking to get an inspection or even if you are homeowner looking to get an honest assessment of your HVAC/ducting work.read more

I highly recommend Connolly Heating and Air Conditioning! Brian came out and made sure we understood the process,... options, and financing. Roman, Russ, and Colin were efficient and professional and everything was completed right on time! At the end of every day, they cleaned up so well you could hardly tell they had been here and they were very conscientious about keeping my pets safe and wearing masks.read more

We replaced a 30+ year old furnace, added new central air, replaced old ducts, and insulation. We couldn't be happier... with the work that was done. The team, Nick, Colin, Russ, and Raul were very professional and knew their stuff. We prefer to do business with a family owned company. Give them a call for a quote, you may even get Brian.read more

We have used Connolly Heating and Air for years and have always had amazing service. Today, however, they REALLY went... above and beyond so I thought I’d do what I should have done a long time ago... give them a HUGE shout-out! They are one of the most professional, efficient, and responsive companies I have ever dealt with and I highly recommend them to anyone looking for a trustworthy, honest, and empathetic organization. You will not be disappointed! Norm and his entire team are truly top-notch!!!read more

This company came through for us with flying colors! They supplied a competitive bid and followed through on their... delivery. Even though they expected to complete the job in two days, they finished in one day. They completed everything as expected, installing a new heater and air conditioner. It works great! Highly recommend them!read more
