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.
