Here is a common scenario that happens in the modern home. You notice that the heater has not cycled on in quite some time. The air is getting chilly, so you go to the thermostat. You try turning it a few degrees warmer, but nothing happens. You call out to your spouse, or say to yourself, “I think the thermostat is busted!”
As heating technicians, our jobs would be a lot easier if the thermostat really was the source of most heating system breakdowns. While this is rarely the case, it is possible that your thermostat is at fault for your low heating or complete system shutdown. Read on to learn when this is the case, when you can solve the problem on your own, and why you may have to call in our expert technicians.
Every forced-air heating system, like a furnace, has a filter (or it should). When you run your heater, it first sucks in air from around the home and then heats it before blowing air back out to the rooms. Any dust or debris in the air could get sucked in and forced out with it, but the furnace helps to prevent this and protect your heater from damage that could be caused by that incoming debris.
