Some homeowners may complain if their furnaces won’t turn on. However, a furnace that won’t shut off can be every bit as concerning, especially with its potential to cause damage. Let’s review a few reasons your furnace runs constantly in your Oak Ridge, TN, home.
Incorrect Fan Settings
Without realizing it, you may have accidentally set your furnace’s fans to run continuously. The fans have two settings: “on” and “auto.” “Auto” means that they will run whenever your thermostat signals your furnace to run, but “on” means that they will work at all times.
When this happens, you may get the impression that your furnace refuses to shut off. Luckily, the solution is simply to turn the settings back to “auto.”
Airflow Obstructions
Airflow obstructions can hinder your furnace’s performance in various ways and cause abnormal results. To give one example, dirty air filters might prevent your furnace from pushing warm air into your home, which may lead your thermostat to direct it to keep working. Clogged valves and leaky ductwork can produce the same effect.
To be sure that your furnace doesn’t have gunk sitting in its components, you should periodically schedule maintenance services for it. We recommend doing so at least once per year.
Wrong System Size
Finally, it’s possible that your furnace is too small for your home. If so, the system will have to constantly struggle to keep your indoor environment consistently warm. Consequently, it may remain on all day and never pass through ordinary heating cycles.
In that case, the system’s components will experience extreme stress and may fail much earlier than usual. The only lasting solution to these problems is to have a team of professionals remove your old furnace, perform the calculations necessary to find the size your home needs and install a new system.
