John Mullen Heating and Air Conditioning Co is a local company in the Pittsburgh Area
John and his crew are fantastic, very reliable, and knowledgeable of their trade.
I have known John for a long time. He comes from a great family and is a hard worker.
He sent his helper to my house this past summer for an air conditioning checkup.
I called on John for his expert advise when the neighbors below though there may be a leak
from my unit. He worked with my neighbors and found no problem. But he completed some preventive repairs and solved any future problems.
I have recommended John’s company to others.
Keep up the good work.

When the furnace in our home failed, I called John Mullen, an HVAC expert to replace it. After removing the old furnace, he and his men cleaned the area and installed the new furnace and replaced all the duct work. All the work was done quickly and efficiently. I would recommend his company to anyone needing HVAC work done.
