Reasons Why Your Furnace Won’t Turn Off

Furnace That Won't Turn Off in Aitkin, MN

An overactive furnace can quickly impact your comfort and utility bills. Constantly producing heat can also put harmful stress on the system, lowering its efficiency and potentially its life span. Here are a few of the most common reasons behind overactive furnaces.

Faulty Thermostat

Your thermostat should signal your furnace when to kick on and turn off. If the device is suffering from faulty wiring or incorrect settings, your indoor comfort can be impacted. Thermostats older than 10 years are more likely to malfunction and skyrocket your regular energy usage.

Clogged Air Filter

Your HVAC filters work to regulate the amount of air in your furnace. When they become clogged, the system can struggle to get enough air, which will make your furnace work harder. Be sure to regularly switch out your filters and use high-quality options that fit your unique household.

Leaky Ductwork

The heat in your home must travel through the ductwork before reaching your living areas. If your ducts are leaking air into the walls and uninsulated areas, your furnace will stay on to make up for that lost heat. You may feel perpetually cold and uncomfortable even though your heating system runs for much longer than usual.

Compromised Blower Fan Motor

Blower motors can easily become overheated due to clogged filters and restricted air supply. They may start tripping your circuit breaker or making odd grinding and squeaking noises. Call for an expert immediately to limit the spread of damage and restore your furnace’s heating efficiency.
