"Bruce and Bill of Williams and Associates Mechanical Contracting recently removed and replaced my 18 year old oil fired boiler and added an indirect fired water heater. I had been saving for this project for over a year and had been geeking out in my avid research (Thanks Internet!) of products available, reviews and costs, as well as the reputation and reliability of local heating and plumbing contractors. I knew what I wanted, I just needed to stay within my budget and find a contractor I could trust. It is therefore, my pleasure to let others know, on the same web review sites that I referred to, how overwhelming pleased I am to have worked with Bruce Williams and his team. They skillfully removed and installed the heating system in a day, took pride in their work and took the time to explain the new system and to fully answer all my questions. Bruce and Bill clearly like what they do for a living, have great people skills and work very well together. I was able to get the very best of products and still come well under budget. I cannot thank these guys enough! Honest, Professional and Reliable! My dusty, unfinished basement with my new Viessmann boiler, Carlin burner and HTP indirect fired water heater is now my favorite part of the house!"

"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."

"Bertram was very professional and very careful with bringing in and taking out old and new boiler. When coming in and out layed cloth to protect flooring etc I highly recommend him. I was given several quotes in a timely manner and he was very honest and helpful in helping me to make my decision to have him install the bolier. Will recommend him to friends and family."

"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"

"We were looking to facelift a small bathroom without a major remodel. TJ did not try to oversell the project (he actually suggested doing less rather than more) and was able to have a custom counter/sink made for a very tricky cabinet base. His crew installed 2 toilets, a light fixture, and a new sink top (including all new plumbing in the cabinet) in less than a day AND in the middle of a pandemic and snowy weather. They laid drop cloths from the front door to the bath, wore masks, and left no clean for me. Communication via email was easy throughout the process and Lisa , in the office, was delightful anytime I had to call. We will definitely reach out to TJ at W.B. Dickenson if we are need of another facelift, a full remodel, or just have some plumbing work to be done!"

"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 FAQs, answered by experts

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

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.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

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.
