A furnace is overheating if it keeps turning off, a burning smell starts emanating from it or your living spaces aren’t getting any warmer. This issue won’t go away on its own, which is why it needs to be addressed as soon as possible. Ignoring it completely can cause extensive damage to the whole heating system, shortening its service life.
In this blog, W.E. Beavers Jr. Heating & Cooling, your trusted contractor for HVAC repairs and installations, shares the potential causes of an overheating furnace.
Restricted airflow. Insufficient airflow causes the unit’s interior components to get too hot. This happens when you forget to change its air filter regularly. It can get clogged with so much dirt over time that the whole system starts working twice as hard, reducing its efficiency and performance. Make sure to check your furnace’s filter and replace it accordingly. You may have to replace it frequently if you have pets at home or live with many people.
Excess dirt. A clogged furnace air filter can no longer perform its job well. As a result, the dust and contaminants that it’s supposed to catch start collecting on the surface of the furnace’s interior components such as the blower motor and heat exchanger. Prevent your furnace from overheating by having the system inspected and cleaned by a certified heating services technician.
Mechanical failure. An overheating furnace can also be the result of mechanical failure, when the electrical wiring, blower motor and heat exchanger are subjected to excess strain. Scheduling routine maintenance with your HVAC technician can go a long way in keeping its moving parts in good working condition. They can recommend replacement parts if they spot signs of premature wear and tear on some of the components.
