"Everything done exactly right, on schedule (ahead of what I was expecting). AJB quoted a Columbia boiler, which cost a little more than the others, but I believe will be worth it. Worked almost 13 hours the first day and a couple more the next day to get the job done. Cleaned the area and ensured everything was operating properly."

Customers say: Quality work

"I have used Freedom Comfort Services in the past installing mini-split system and now (at another house) replacing an oil furnace with gas. They are priced better than the other companies that I got quotes from AND they took the time to measure the spaces in the house to know what I would need. They communicated great and were always punctual. When our old furnace went out they worked quickly to order a new one and when it came in, made sure it was installed that day. You can tell that they care! That's important to me."

"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"

"Their service was excellent; they did not give up until they found and fixed the problems with my nonfunctioning 55 year-old heating system. I highly recommend them for their professional and friendly service."

"This is the second time that we have used B.A.R. In December our furnace was leaking, it was cold and Henry came out very soon after calling. He needed to do an "innovative" fix, which was awesome because we were leaving on vacation. There was no question then who I would call when we woke up recently and it was COLD. This time there was no hope for the furnace. Henry once again responded quickly to my call for help, and he has once again had to come up with a "crafty" fix with the install of a new furnace. They are the best, and I would highly recommend them for both repairs and new installs. They will work until your problems are solved. They are honest and I trust them which is a very important aspect of hiring any company."

Install Boiler questions, answered by experts

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.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.
