Your furnace keeps your house warm during the chilly winter months, so it’s annoying when something isn’t quite right. One frequent issue is a furnace that endlessly turns on and turns off over and over. This problem is called short cycling. It stresses your furnace and may result in expensive repairs or even early failure.
Short cycling can happen for a few reasons. Before you request furnace repair, research the possible causes and how to resolve the issue.
The HVAC filter traps airborne dust, hair and other substances that could wreak havoc on furnace. If you don’t replace the filter often enough, it can get filthy and decrease the airflow. When this happens, a safety feature shuts off the furnace to prevent getting too hot. Inspect the filter, and if it’s dirty, install a new one. Going forward, replace the filter every 30 to 90 days to keep your furnace from short cycling.
A dirty filter isn’t the only issue that can restrict airflow and overheat your furnace. Walk around your home and look for unopened or blocked air vents. For proper system balance and performance, keep all registers open, even in unoccupied rooms.
The furnace blower has blades that move air through the ductwork. If they are dirty, the air won’t move correctly, leading to overheating and short cycling. Frequently replacing the filter is the simplest way to avoid a dirty blower wheel. If the blades are already dirty, request furnace maintenance to have them cleaned.
Check your thermostat next. This is the core of your HVAC system and tells the furnace what to do. Ensure the thermostat is set to heating mode and auto fan with the desired temperature showing on the screen. Try replacing the batteries. Also, check whether the thermostat is in bright sunlight or near a heat source that could affect the temperature reading. If you have a smart thermostat, go to the manufacturer’s site for troubleshooting tips.
The flame sensor turns off the gas valve when no burner flame going. The sensor can’t detect the flame if it’s coated in soot, so the gas shuts off sooner and the furnace shuts off. Leave the work of repairing a sooty flame sensor to a pro like Calverley Service Experts.
When it involves heating and cooling equipment, larger isn’t always right. A larger system heats up your house too fast, leading to unpleasant temperature swings and short cycling. The only way to resolve this issue is to request new furnace installation.
