Your furnace keeps your home warm during the harsh winter months, so it’s frustrating when something isn’t quite right. One routine situation is a furnace that endlessly turns on and turns off all the time. This problem is known as short cycling. It overworks your furnace and might result in expensive repairs or even early breakdowns.
Short cycling can be caused by for several reasons. Before you request furnace repair, research the likely causes and how to fix the problem.
1. Dirty Air Filter
The HVAC filter traps airborne dust, hair and other pollutants that could damage the furnace. If you don’t change the filter frequently, it can get dirty and block the airflow. When this takes place, a safety feature turns off the furnace to stop getting too hot. Inspect the filter, and if it’s dirty, replace it. From here on out, change the filter every 30 to 90 days to stop your furnace from short cycling.
2. Clogged Air Vents
A dirty filter isn’t the only thing that can lower airflow and overheat your furnace. Walk around your home and check for shut or obstructed air vents. For recommended system balance and performance, keep all registers open, even in unoccupied rooms.
3. Dirty Blower Wheel
The furnace blower consists of blades that move air through the ductwork. If they are dirty, the air won’t flow right, creating overheating and short cycling. Frequently putting in a new the filter is the easiest approach to stop a dirty blower wheel. If the blades are already dirty, request furnace maintenance to have them cleaned.
4. Faulty Thermostat
Examine your thermostat next. This is the core of your HVAC system and gives the furnace instructions on what to do. Ensure the thermostat is set to heating mode and auto fan with the desired temperature displayed on the screen. Try replacing the batteries. Also, check whether the thermostat is in full sunlight or near a heat source that could influence the temperature reading. If you have a smart thermostat, visit the manufacturer’s site for troubleshooting guides.
5. Soot-Covered Flame Sensor
The flame sensor switches off the gas valve when no burner flame on. The sensor can’t find the flame if it’s sooty, so the gas switches off sooner and the furnace turns off. Leave the job of repairing a dirty flame sensor to an Expert like Abbey Air Service Experts.
6. Oversized Furnace
When it includes heating and cooling equipment, larger isn’t always better. An oversized system adds warmth to your house too quickly, creating unpleasant temperature fluctuations and short cycling. The only way to take care of this situation is to do new furnace installation.
