"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."

"I took off work. The technician arrived said they were not qualified to work on Combi-tankless boilers; though I had explained over the phone when making the appointment; the Combi boiler I had, and the code e352, that I couldn't maintain heat. The boiler shutting down, and I worked nights; so please don't arrive before noon. Upset, I bleed the system myself and refilled going by the Navien manuals I had. The code e352 was gone. The psi was lower, the boiler didn't shut off. But psi was still a little high above 30. Hurley and David could only reschedule for the next day 12Pm to 4PM. Getting up (sleeping in because I work nights) I had 3 phone calls from 9:30am on, Hurley and David saying they were unable to reach me. That additional frustration got ironed out. A technician was sent. His name is Macauley. He immediately knew I needed an expansion tank and replaced same. The price was high, but his professionalism and communication skills made all the difference. And the psi normal"

"Excellent from start to finish. Called early morning and left message with service. They called back shortly after opening and confirmed appointment. They showed up at the expected time and quickly and professionally fixed the leaking pipe. In addition they made time to look at waste line and aging boiler to provide estimates."

"Everything was great. Very professional. I have a 2nd floor condo unit so the vent needed to be accessed by ladder. We discussed this when we set up the appointment. There was an extra fee due to the height of the vent but we agreed on the cost prior to the appointment being set, so there were no surprises. I would use this company again. Thanks."

"The owner returned my call promptly and after discussing the services needed he emailed me a detailed estimate and answered all my questions. I was confident after speaking to Joe that the work would be done exactly as I had requested. His son, Anthony, was the actual serviceman and he was courteous and my questions were answered and together we agreed on the best plan to cover everything that needed to be done in the most efficient and least disruptive manner. He worked tirelessly to complete all the extra services I hadn’t thought of initially which involved cleaning the bathroom vents, replacing the bird guard on the outside of the dryer vent and also cleaning the refrigerator coils which it turns out were in pretty bad shape! He showed me pictures of before and after and the difference was remarkable. Although he needed to work longer to accommodate all my requests, he was kind and patient and did not make me feel guilty for adding extra work, although I felt bad that he had a very long work day! If you are looking for courteous, reliable,and professional service this is the company to choose!"

Install Boiler FAQs, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.
