When your Southshore, LA, furnace runs properly, each cycle will last between 10 and 15 minutes. In most cases, it’ll run two or three cycles per hour to keep your home warm. Here are some problems that will cause your furnace to run constantly and what you can do about it.

Wrong Thermostat Setting

If you don’t set your thermostat correctly, it will seem to run constantly, but in fact, it’s just the fan. On your thermostat is a fan setting with the options for Auto and On.

If you have it set to On, the fan will run constantly, though the furnace doesn’t continue running. Simply change the setting, and your fan should shut off.

Dirty Air Filters

Your air filter is the key to your furnace working effectively. As your system runs, small particles collect on the filter, slowing the airflow into your system.

Without good airflow in, your system cannot push warm air out. This results in longer than normal heating cycles and sometimes even running continuously.

Thermostat Malfunction

Beyond having the wrong fan setting, your thermostat may malfunction, including having a faulty temperature sensor or switch. When this happens, it won’t signal to your furnace to turn off at the right time. Plan to replace your thermostat every 10 to 15 years to ensure the switches and sensors continue working optimally.

Faulty Blower Motor

Your blower motor is responsible for drawing cool air into your furnace and then pushing warm air into your home. If your blower motor malfunctions, then it reduces the amount of air moving through your system, similar to the way dirty filters do. If you think your blower motor is malfunctioning, call a professional technician for a furnace repair.

Lax Maintenance

Your furnace must receive routine maintenance to continue working effectively and reach its full service potential. Neglected maintenance creates airflow restrictions throughout the system and allows components to run inefficiently. The collective result is longer or continuous heating cycles.

Make sure your furnace is heating effectively this winter and running appropriate cycles. Call today to schedule your furnace maintenance with our NATE-certified technicians at Caribbean Breeze Heating & Cooling.
