"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"Joe and his crew did an excellent job installing new boiler and indirect hot water system. I made the decision to convert to gas and replace my 21 year old oil fired boiler. Everything went along smoothly and professionally. Joe kept me informed every step of the process and job was completed on time. I would definitely recommend."

"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."

Install Boiler FAQs, answered by experts

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.
