Professional, effective service on gas furnace and one gas fireplace for one hour cost $279.04 - outrageous!!




Jasper diagnosed that the gas furnace problem was caused by a partially clogged exhaust flue, and cleaned it out. He then scraped and cleaned the fireplace pilot light burner, which improved its ability to light the fireplace. He also cleaned the fire place glass which I told him that I had done in the past and could do again. I believe that only the one invoice Diagnostic Fee and Truck Charge of $106.79 should apply and not the second invoice Preventative Maintenance charge of $ 173.25. The total charge of $279.04 for one hour of work is outrageous!! I did not state my objection to Jasper as I believe it was unfair to do so to him.
