"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."

"Mull Brothers gave us an estimate on installation of central air conditioner in our old home.  Their price was slightly higher than some competitors (although not by very much), so we didn't end up using them.  However, I was very impressed with Mr. Mull's visit.  He was knowledgeable and thorough, and gave me great information without using any high-pressure sales tactics.  I will probably contact them again in the future for my next project.

"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."

Highly recommend tandem mechanical. Out side central air condenser is next on my list and I will for sure have these guys back."

Install Boiler questions, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

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.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.
