Best boiler installation pros near Mars, PA

"Originally had them out for routine maintenance, unfortunately our boiler was misfiring and they tried everything to for it but ended up needing a replacement. Went above and beyond to explain each reason why the 70 year old boiler needed replacement and showed me the deficiencies and wear. Best price and were extremely professional and prompt. Could not recommend them more"

"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."

"From start to finish, Tim and his team did an excellent job. They installed a new natural gas furnace and air conditioning system. Their knowledge, expertise, and customer service sets them far above their competition. Do not hesitate to use North Pittsburgh Heating Company, simply put, they are the very best at what they do."

"Easy to contact/schedule. Good to work with. Left everything exactly how it was. Would hire for plumbing again."

"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."

"Job was done right, installers were very prompt and professional."

"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."

"Everything went wonderfully. After purchasing the offer, I was contacted almost immediately to set up an evaluation. They wanted to send out an employee to make sure that nothing else was needed to complete the project and he was here within a few days. I was then able to schedule the installation and it was a week later. I was contacted to ask if I was ok that the installation was pushed back a few hours due to delay in another job. They did a great job of always keeping me informed of what time they would be here. My installation, by Denny, was done quickly and professionally. He went over everything with me and made sure that I knew how the unit worked. He suggested a few things that I could have done on my furnace as well but didn't push anything on me. I found the whole process to be professional and I would absolutely use them again in the future."
