Get matched with top boiler installation pros in Danbury, CT

"I enthusiastically recommend this company. Mehmet was always prompt for appointments and texted to let you know he was on his way. His crew worked from 7 am to 7 pm and got our new central A/C system installed in one day during a heat wave. Very professional outfit, polite and cheerful to have around."

"Talk about Top Quality service! From the professionalism of Daniel, to the great job done by Humberto and Ernest. I couldn't have had a better experience in a bad situation. They replaced our steam boiler, and our water tank and did a wonderful job. We have a warm house again thanks to them! Humberto, Ernest, I take my hat off to you!"

"I always trust Chris as my technician to deliver superb service re: my furnace/boiler, hot water tank, split A/C system, and dehumidifier. It's a pleasure to greet him semi-annually, since he's courteous, pleasant, and professional, and since he answers all my questions re: my heating and cooling systems. I trust this talented tech being inside my home and tuning up all these systems. Kudos to Tyler Heating & A/C for hiring Chris as its employee."

"Oct. 6 2025 it went quick. I received an estimate of The job first. The work was done correctly. It didn't take long. If I need plumbing service again. I would contact Cassidy plumbing & Heating."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"They were great! Even found a way of adding a 40 gallon water heater to a smaller space. Which has been wonderful! They worked in a VERY tight space and got the job done! I highly recommend them! Will be using them to install my central air as well!"

"The installation went very well. When a part arrived damaged, they discovered the issue and had a new one delivered within an hour. The installers were very conscientious and took precautions to avoid leaving a mess. There were two relatively minor issues that we became aware of after the installation and Bell came back promptly and fixed them without complaint. I don't have a good context for the price, but it seemed reasonable in the context of my neighbor's installation and my previous dealings with them on service had been good."

"Furnace was not operating because the company's automatic delivery system ran me out of oil.
Technician showed up promptly and got the furnace operating but could not get heat into the house. Had to reschedule to have zone valves replaced. Technician show up late and didn't have the required parts. Had to reschedule again.
The third technician showed up on time with all the correct parts and worked most of the day to get the system operating properly.
He was completely knowledgeable and very conciencious that everything was working correctly.

"Randy from Schede worked on the ductwork Installation and was very professional and knowledgeable; he explained everything he was doing in a way that I could understand. I would definitely recommend Schede to anyone who HVAC services!"

"I looked at over 10 different mini split installers over a year and had just about given up. It wasn't until I found Kelley's Heating & cooling. They were honest up front and worked directly with an electrician (who also did an amazing job!) to quote me the best price. Mariana in the office worked directly with me to ensure I got all the Energize CT rebates pre-approved and factored into my quote. By far there team was light years ahead of all the other installers I met with who didn't even include electrical. The fact that they are Fujitsu certified was also a big win in my book. I can't say enough positive things about the installation team. They were professional, clean, and organized. Within about 4 hours they had my new mini split wired in looking great and sounding super quiet. Would highly recommend this team."
