"I have had air systems mechanical install my high efficiency furnace few years ago and recently install my central air. Their prices are lower than the rest. They are always courteous and professional from salesman to office staff. I have nothing negative to say. Always on time for routine furnace tune up appointments. A great company to deal with."

"When I made the first call, the receptionist was friendly and helpful. A repair man was here within 2 hours (amazing!). He was professional, knowledgeable, forthcoming with information and the possible options, and he was very efficient. He was careful to leave no mess: nothing left behind, no foot prints on the floors or rugs. We had Sullivan come back a week later to replace the boiler, and again the experience was excellent. We've met several service people and they have all been friendly, respectful, thorough and very helpful. I give them the highest recommendation possible."

"John stopped one day to quote us a price, we arranged for the work and a few days later our new furnace and AC units were installed. John's helper arrived promptly, removed our old furnace and AC unit and installed the new one along with a new air cleaner, new thermostat and all new piping. The job was competed professionally and in one day. And everything was cleaned up before he left. We did have one small issue with a leaky condensate drain pipe which was quickly remedied the same day we discovered it. I would recommend John Mullen Home Repair to anyone. The best part is that he is a local business and we were really pleased with to deal with someone local."

"This plumber is friendly, and the price is very reasonable. He may not be your full-service, know-all-and-do-all contractor, but he won't charge you $300 for an hour of work. Great value for the price. And he is in Moon Township where I live - I am going to hire him a lot in the future."

"I had a fifty year old furnace that provided its last breath on the coldest day of the year and John the owner saw to it that I was financed and gave me a very good price. It was flawlessly installed the next day by his courteous staff and they hauled away the old furnace too. Great job! Thank you."

Install Boiler questions, answered by experts

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).
