Best boiler installation pros near Harwinton, CT

"The thermocouple on my gas-fired boiler needed to be replaced, and the pilot needed to be cleaned. The tech was helpful and forthcoming with information. Took about an hour, as my boiler does not have easy access. Would hire again!"

"Outstanding service. I called because my boiler was leaking and the after hours technician responded within 30 minutes of our call. Our coil plate and gasket were rotted and bolts had snapped and we decided that we would replace the boiler because ours was 16 years old. We spoke with the owner and sales manager the following morning and were told that they would be happy to replace the boiler if that is what we wanted to do but they felt our boiler could be repaired at a fraction of the cost and no where near the end of it's usable life. So we decided to go for the repair and they were right, it worked like a charm! So instead of a $9,000 boiler and indirect replacement, we spent $472 and my boiler was up and running the next day. We have used Advanced Mechanical Services for our conversion from oil to natural gas and for our air conditioning installation. They have always been very professional, courteous, prompt and their pricing has always been competitive. I would highly recommend them."

"Joe went out of his way to ensure our heat was back on, this company really cares about its customers. Hard to find these days, Great Service!!"

"I needed quick service on a 45 year old hot water boiler in a 1938 house I recently purchased.  While I could get the pilot light lit, nothing I did could get the boiler to fire (water was circulating).
On Wednesday I contacted Pelletier Mechanical as Gary (the owner) had been out giving me estimates on the various repairs and modifications I wanted to make.  While Gary was out of the office training (again), Laura his admin arranged for Bill to come out on Friday.  She provided an estimated cost (right on) and a 2 hour window.
Bill showed up on time and after a brief discussion get right to work.  Bill spent about 15 mins. systematically determining why the flame would not light.  He discovered that there the gas was not making it to the main control valve.  He reset the safety shut off valve and the problem was solved.  He then checked all the radiators to make sure that hot water was making it through out the house.  After we determined that the upstairs radiators were not getting hot, Bill checked the water pressure and determined that the pressure was insufficient to fill the upstairs radiators in "real  time".  He suggested that the culprit was the 45 year old water valve and pressure release valve which being cast iron tend to corrode and clog in time.  He proposed a replacement solution and priced it out, and offered to pick up the parts and replace the valves that afternoon.  I decided to wait a few weeks so I could consider replacing the entire boiler.
While we were waiting on the boiler to come up to heat, Bill and I walked through the basement looking at the existing plumbing, tracing the water flow path and discussing the possibility of replacing the hot water tank with a tankless unit. (The hot water run is about 60-65 feet from HW tank to kitchen, bathrooms, etc.)  Bill, like Gary, is knowledgeable and informative.
I will have Pelletier Mechanical  back to do more work on the house."

"Perfect as I expected and more. East Coast installed a central air system and a ductless heating and calling system in my house. They were much affordable than their competitor."

"I recently had a great experience with Chernin HVAC. They were professional and thorough in maintaining our old AC system. The technician provided valuable recommendations for a future upgrade, highlighting how it would save on energy costs and improve cooling efficiency. I highly recommend Chernin for its expertise and outstanding customer service."

"I worked with several contractors to identify the best solution and price for my new boiler/tankless water heater. Chad was patient and thorough in his explanation of my options and costs. He installed a high efficiency system in 2015 that has worked flawlessly. We NEVER run out of hot water. The space in the basement has been cleared with the elimination of the old boiler and stand alone hot water heater and best of all.... my propane gas usage is 1/3 the amount it has been in previous years. Chad did a beautiful job on the installation. His work is meticulous and I've often told my friends/neighbors it is a work of art. He also helped me with the rebates and finance options available. I could not have asked for a better contractor. Chad was responsive, on time and left my house better than he found it. He removed the old equipment and even helped me by installing a new double filtration system for my well which he configured much better than the previous single filter. Based on this install and level of service, I would give Chad the highest possible recommendation."

"Very positive experience. They responded immediately when I sent the request. The gentleman who called asked me questions about my current setup and had a technician out promptly. The quote was reasonable and the job was completed in one day. Staff were friendly. Happy customer!"

"Tech found that thermostat had hidden switch under cover. He suggested a better quality programmable thermostat which he installed & is running great."

"The technician was very professional and helpful in describing the system and the best practices in light of being a new homeowner without any experience with fuel oil heating systems.
