"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!"

"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.

"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."

"The thermocouple on my gas-fired boiler needed to be replaced, and the pilot needed to be cleaned. The tech was helpful and forthcoming with information. Took about an hour, as my boiler does not have easy access. Would hire again!"

"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."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"Precise HVAC was wonderful. I actually was going to get more quotes but after working with their salesperson I decided to not even bother. They answered all my questions and made suggestions for things I didn't know about. I'm not even sure I care if I got a better quote or not. With Precise I know that they cross the t's and dotted the eyes and I don't have to worry about missing something."

Install Boiler questions, answered by experts

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

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.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

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.

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.
