How Do I Keep My Furnace from Overheating?

When it comes to your home comfort systems, nothing puts more stress on your furnace than peak season during the winter. In the Springfield, MO area, sub-freezing temperatures threaten to turn your two-story Tudor into an igloo. However, with the unit running all the time, you’ll have to watch out for signs of overheating. When a unit overheats, one or more components inside the unit may be susceptible to breaking. However, you can combat this by preventing your unit from overheating. Trust in the expertise of our professionals at Air Services and we’ll provide you with expert tips and show you how to do it.

Use the “Auto” Setting

One way to prevent overheating of your system is to use the thermostat to your advantage. While it may be nice to have your furnace blowing toasty air 24/7, it’s not good for your system. The auto setting will allow the fan to shut off when the house is the proper temperature or when no one is home. You can schedule specific times for the thermostat to stop heating the whole house when everyone is sleeping at night or gone during the day. This allows for the unit to cool and prevents overheating from occurring. Preventative steps are the best way to avoid unnecessary and costly repairs in the future.

Clean/Change Your Air Filter

Another reason your unit may overheat is due to a blockage of airflow. If you’ve forgotten or neglected to change the air filter in a while, and it’s now clogged with dust, debris, or even mold, this could be blocking the airflow to the rest of your system. This is a problem because it can then cause the components to overheat, especially the inside coils that are vital to the heat transfer process. The evaporator coil has hundreds of tony air passages that are crucial to its function, and if those passages become obstructed, your system will no longer provide adequate heat. It will struggle to work harder, run longer, and use more gas or electricity, resulting in an increase in your utility bills. When you need your filters changed, you can rely on Air Services to ensure your indoor air quality.

Limit the Losses

If you notice any areas that are particularly drafty or windows and doors that have leaks, it’s best to seal those things up before the winter season hits. If these cracks, leaks, or openings aren’t sealed properly, they could let cold air into your home, making your system work harder to regulate the inside temperature. These things could be causing your unit to run overtime, which puts you in jeopardy of overheating. As you know, if your unit overheats, it will likely lead to expenses like increased energy bills and system repairs. If you want to avoid that, make sure your doors and windows are adequately sealed.
