"We were switching over from oil to propane heat. It was a pleasant experience from the time we first met Jason who was very knowledgeable and a joy to talk to. The installers were very professional and did a great job. Aire Serve worked seamlessly with Curtis oil and job was completed in 1 day. We are warm happy campers and would definitely recommend Aire Serve and Curtis Oil & Propane."

"Mike was friendly and efficient. He hooked up our gas stove (and had warned us when we first called to make sure we had the proper electrical for it...which we didn't and arranged thanks to him) . He also took time to check out another job we might do in the future. Would definitely work with him again."

"When my computer refused to boot up, I took it to Jim and he diagnosed a virus infection as the problem. He got the machine working again by installing a new hard drive and adding more memory for increased performance. Just a couple of weeks later, the computer again was having problems. This time, Jim dianosed the culprit as being the machine's original memory. While I decided not to remove and not replace the faulty memory for the time being due to cost, Jim upgraded my operating system to enhance the overall system performance. Jim was very professional and timely and was very sensitive to my concerns. Communication is excellent."

"We not only contracted Eric Stone to install a new water heater, but to also move and install a new well pressure tank, which was failing, from under our manufactured home, to an inside storage closet location, and then re-pipe our home water supply from the new inside location of the pressure tank to the newly installed water heater. When I first met Eric for an initial bid, I felt very confident in the fact that I had chosen the right plumbing contractor for our project, and his knowledge and expertise plus his likeable demeanor did not let me down. Eric's bid was fair and complete, he and his crew showed up on the agreed date and time, and his crew of two additional plumbing techs, Ethan and Hunter, were very knowledgeable, courteous, and just all around good guys and a delight to have them working my home. The finished product of the installation was exactly what I had envisioned, and the work area was cleaned up on completion. Needless to say I am thrilled to death with Eric's work and would highly recommend his company to anyone contemplating a like project."

"Hired the Comfort Company to install a new propane high efficiency furnace, air source heat pump and take out my old nasty oil tank. Very satisfied and my wallet took a smaller hit than I thought it would! Highly recommend!"

Install Boiler FAQs, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.
