4 Causes of a Constantly Running Furnace in Johns Creek, GA

Normally, furnaces turn off and on frequently in order to maintain a comfortable temperature in your home. If your furnace in Johns Creek, GA, is constantly running, it could be a sign of a problem. Read on to learn about four common things that make a furnace run continually.

1. Dirty Filter

A dirty filter can impede airflow and cause the furnace to run longer than necessary to maintain a comfortable temperature in your home. We recommend changing the filter every three months or more frequently, if needed.

2. Malfunctioning Thermostat

If your thermostat isn’t working properly, it can cause the furnace to run constantly to maintain the desired temperature. Check the batteries in your thermostat, and if it’s an older device, consider swapping it for a newer one. Smart thermostats can let you program your furnace’s activity, control your home’s temperature when you’re away and even potentially diagnose issues.

3. Leaking Ductwork

If your ductwork is in poor condition, the hot air from the furnace can escape through cracks or unsealed area, leaking this warm air into your basement of attic area. This, in turn, means that the furnace needs to run longer to get the appropriate amount of heat throughout your home. It may be worthwhile to have a professional inspect your ducts for wear, tear and damage.

4. Damaged Blower Motor

If there’s something wrong with your furnace’s blower motor, it can cause the furnace to run constantly in order to generate heat. A variety of things, such as dust, dirt or even age, can cause a blown motor. When you have problems with your motor, we suggest contacting a professional to inspect it.
