"Advanced Mechanical Services (AMS) went out of their way to get our new oil tank installed and the old one removed in the winter. We were experiencing issues with our old tank where our oil company could not fill the old tank. AMS worked closely with us to install the new tank quickly. They kept us in the loop and were on time on installation day. The installers were professional, kept us informed and did an excellent job. In addition, they cleaned up after themselves. We also use them for our annual furnace cleaning. They always do a great job and have come out on emergency calls a few times over the past 25 (or more) years. I highly recommend them."

"From start to finish with my project Gary and his team were helpful, responsive, knowledgeable, and professional. Gary considered all of my heating/ac/humidity concerns, took full measurements of my condo, system and energy calculations, and recommended three good options of Bryant electric split heat pump systems. I ended up choosing the most efficient top of the line model as I was replacing a 25+ year old unit. I felt that the price was fair and even if I could have found a slightly lower price, I was very comfortable hiring Pelletier based on Gary’s initial follow-up, professionalism and thoroughness when quoting my job. They also went the extra mile when doing the installation under terrible weather conditions. I’m very pleased with the end result. I have no hesitation in recommending Pelletier."

"Juan was great to work with. He efficiently cleaned and serviced our Gas Boiler. He provided some education about the capability and also noted we had a great boiler that was maintaining strong water pressure and temperature. Great service. Price was appropriate for non-emergency level work! I would easily use them again."

He explained everything clearly, worked neatly, and made sure everything was running perfectly before leaving. You can tell he takes pride in his work. I highly recommend Asante to anyone looking for quality service and a smooth, stress-free installation. Great experience overall!"

Install Boiler questions, answered by experts

Costs depend on issue severity, parts needed, and labor rates.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.
