Joshua came to my home to investigate why my furnace had stopped working and would not restart until after it was off for nearly 3 hours. What he found was that I had installed a screen over the outside opening of my wall exhaust to keep the box elder bugs out. He explained that because of the humidity and the cold weather that it had created a film over the screen and that slight blockage told the furnace to shut down. So he removed it and the furnace seemed to work fine. I found him very knowledgeable, informative, friendly and polite. Thank you Air Mechanical.
Sincerely
David Mosimann
