Why Does My Furnace Overheat?

The last thing you want is your furnace to overheat during a cold Denver, CO winter. Once it overheats, the entire system can shut down and be impossible to restart. You can avoid many problems by understanding and recognizing the most common reasons why your furnace is overheating.

The Furnace’s Age

The average furnace will last 20 years with routine maintenance. Once a furnace reaches a significant age, it’s more likely to overheat. If your furnace is approaching that 20-year mark, you may want to consider replacing it, which can be cheaper than frequent repairs.

Your Vents are Causing Issues

You may think it’s a good idea to close several vents in order to control temperature in rooms you don’t use, but this can create problems. Closed vents trap hot air, which puts pressure on the furnace and increases the chances of it overheating.

Issues with the Furnace’s Inner Workings

Your furnace contains many delicate components. When a problem arises with one of these components or the wiring, it can overheat. We can assist you with this by locating and fixing any issues.

The Furnace Isn’t Maintained Properly

Without routine maintenance, your furnace could have unnoticed problems that can lead to it overheating. During a furnace inspection, we can locate and repair small issues before they cause larger problems.

Not Enough Airflow

Your furnace needs adequate airflow to avoid overheating. If the furnace’s filter isn’t changed regularly, it can become blocked with lint, dust and debris. Once this happens, the furnace can’t cycle the hot air properly.

You can avoid having your furnace overheat by being diligent with your maintenance and watching for the issues mentioned above. If you do experience a problem with it overheating, call Apple Aire Heating & Cooling so that we can identify the problem and repair the furnace quickly.
