"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

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

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.
