Best home cleaning systems did the annual cleaning of my furnace. They did not know what they were doing and damaged the main contol board in my furnace this caused the Electronic Air cleaner to not work which then led to the whole furnace failing. I just paid the repairman from Bell plumbing and Heating $660 to fix it.
Cons: Did not know what they were doing, Tried to sell me a repair for something that was not broken
