Get matched with top boiler installation pros in Danbury, CT

"I called Mehmet based on the Angie's list recommendation and the terrific reviews. Mehmet worked around my work schedule and came after 5. He identified the problem and installed a new capasitor. He was in and out of here in 30 mins. A week earlier a rip/off big company (Varsity) claimed the unit could not be fixed for under $3500 and recommended I install a whole new system for $11,000. Mehmet's skill, reasonable price and honesty were well appreciated here."

"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."

"Matt and his team did a fabulous job replacing and installing our oil furnace. He also helped with other issues that we were having with our heating and cooling system for years. Very conscientious, courteous and keeps a the place clean,"

"the process was better than I expected. The sale man knew what he was talking about . The installation crew had worked for the company a long time and were also very knowable . When we could not understand a few things they sent out a serviceman just to show us how it works. They also directed us towards financiers and reabate availability."

"The service was prompt. The owner, Louis came to estimate the job and then send a plumber, Kelroy who was worked quickly and was very professional and personable. When I felt the price was steep the owner adjusted it. I will use this company again."

"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."
