Get matched with top boiler installation pros in Darien, CT

"Very please with the install. Vin was very professional and applied due diligence to the project. His oversight and instruction provided the reinsurance that needed. I requested four heating and AC vendors to provide proposals. Tyler was most responsive to my questions and offered me alternatives along with helpful suggestions. My next project is my boiler. I will be turning them in the future."

"Outstanding service and professional installation!!"

"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."

"While out of town, got word basement might be flooded. Called Schede to check boiler and hot water heater.. They went out the same day. Discovered sump pump wasn't working so replaced it. Cost pump and labor $800. Over the years they have responded to many problems, leaking faucets and stuck drains. Biggest project replace boiler for steam heat. Took 5 guys to wrestle boiler down a narrow basement stairway. Patient with a few family disagreements. Nothing to do with them. Installation successful. They've always been prompt courteous and non judgemental when encountering crazy working conditions. Think they are great. Boiler and hot water heater were fine. They installed both."

"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!"

"My first call to this plumber was a very satisfactory experience. I had a whole house water filter and utility sink faucet that needed to be installed. He determined that the filter needed a support bracket that did not come in the box, made an excellent recommendation for redirecting the pipes to secure the filter firmly and make it more accessible. On installing the faucet in the (unheated) garage utility sink he noticed problems with the sink (not designed to be wall-hung and with wrong-sized legs) and pipes (probably broken by freezing). I asked him to install a better sink. He immediately called suppliers and went right out and got the needed bracket and sink and completed the installations. I am very pleased with the results. All the work, including picking up the items at the suppliers within the hour, was completed in a couple of hours. The total cost was fairly high but I feel quite fair for such a job well done. I feel secure that the jobs were very solidly done. I will definitely be calling Bill Duncan for my future plumbing jobs."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"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."

"Celco replaced my house boiler. It is a pleasant experience from quotation to installation. Team arrived on time. Completed the job on time. Clean up the area like nothing has happened. It is priced fairly. It is a peace of mind for using Celco. I have no reservation to recommend it."
