No furnace should run constantly. If the heating system in your Maryville, TN, home refuses to cycle properly, something is almost certainly wrong with it. Here are a few reasons your furnace might refuse to turn off:
Dirty Filters
To function effectively, your furnace needs air to flow through it smoothly. Sadly, there are many ways that debris might get into your system and interfere with this process. If they get dirty enough, your furnace’s filters can be a particularly serious impediment to airflow.
This is why it’s important to regularly change or clean your filters. We advise you to do so at least once every 90 days.
Furnace Is Too Small
Perhaps the issue that prevents your furnace from turning off is too serious for a simple tuneup or repair job. Instead, it may be that your furnace simply isn’t right for your home. If it’s too small, your furnace will struggle to keep your home warm and may end up needing to work all the time.
If those who installed your current furnace performed their calculations incorrectly, you’ll wind up in this very situation. Unfortunately, the only way out of it is to remove your current heating system and install a new furnace that’s the proper size.
Faulty Thermostat
The explanation for why your furnace isn’t cycling correctly doesn’t always lie with the system itself. To successfully keep your home warm, your furnace must work synergistically with your thermostat. However, if the latter malfunctions and can’t send the correct signals to the former, all sorts of trouble may follow.
Usually, difficulties like these arise either because the wiring that connects your thermostat to your furnace is faulty or because your thermostat’s circuitry has sustained some kind of damage. HVAC service technicians should examine your thermostat to discover the real source of the problem.
