"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."

"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."

"I really enjoyed having the work done by East Coast. They were professional, and when I had questions, they took the time to answer them, even if it meant calling in someone else, or coming by on another day to demonstrate some of the features of the system. In my book, East Coast goes above and beyond the contract to really provide customer satisfaction."

"I had a furnace installed 20 years ago. Since then it has been serviced by four (4) well-known Oil companies. To my dismay, not one could figure out why my furnace would get DIRTY as often as it did. It even plugged up within a year. Cleaning after cleaning ($$$ spent). I became very frustrated. Based on a friends recommendation, I called Cromwell Energy. I was amazed at the professionalism of the entire team. When Lou and Rich assessed the furnace they referred to the manufacturer and was advised that the burner that was originally installed and since replaced by another company was not the correct one to begin with! They corrected the problem and I have been trouble-free since. Thanks guys. I wish more companies would provide this type of service. You've got my business and I have since referred them to other family members who are just as pleased as I am. Keep up the good work! Your loyal customer."

Install Boiler questions, answered by experts

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

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.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.
