"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."

"I was highly pleased with Jim's work. He not only accomplished everything on my list, but he made several suggestions on several
issues that added further performance improvements. 
Jim's response time from my original call was excellent. He is very easy to work with, communicates well and is very customer-oriented.
 
The amount he charged me for the work done and considering the time spent traveling to my house, doing the work and answering my questions and giving me advice was very reasonable. 
I highly recommend Jim for computer installation, network issues,  problem resolution and performance improvement. I will definitely call him in the future for any new issues I have.

"Company did a good job last summer with 3 bay windows, so I called them back when the rest of the windows in the house needed to be replaced. On the initial visit, I told the rep that I wanted the same windows as last year. He quickly found the job order and picked up the details of the window make/model/etc without any need for me to reinvent the order. The company had the opportunity to try to upsell me, as I asked them about replacement of the skylight in the bathroom. Refreshingly, they declined to do so and told me that it would be much better to wait until we needed to get the roof re-done, and to do the window at that time. As before, the first guy clearly explained the process: guy 1 to take the order and measure the windows, later follow-up visit from guy 2 to remeasure all the windows carefully before ordering their construction, and then a couple of months later, a follow-up call from their HQ to schedule the install. He gave me an approximate window for this scheduling call. It was a pretty broad time-frame because there had been an unusually large number of people needing custom windows. As before, everything went off exactly as the rep indicated. The install team showed up within a half-hour of the estimated time, and installed 11 windows without taking a break. They removed every scrap of rubbish, vacuumed thoroughly, and left the place as clean as it was when they arrived."

Install Boiler FAQs, answered by experts

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.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

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. 

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.
