Your furnace keeps your house comfortable during the frigid winter months, so it’s annoying when something is off. One common issue is a furnace that continually turns on and turns off again. This problem is referred to as short cycling. It stresses your furnace and may result in expensive repairs or even early replacement.
Short cycling can be the result of 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 regularly, it can eventually be clogged and decrease the airflow. When this occurs, a safety device shuts off the furnace to stop getting too hot. Check the filter, and if it’s dirty, get 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 shut or obstructed air vents. For adequate system balance and performance, keep all registers open, even in unoccupied rooms.
The furnace blower has blades that distribute air through the ductwork. If they are covered in dirt, the air won’t move correctly, causing overheating and short cycling. Frequently changing the filter is the simplest method 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 brain of your HVAC system and instructs the furnace on what to do. Make sure the thermostat is on heating mode and auto fan with the desired temperature showing on the screen. Try replacing the batteries. Also, check whether the thermostat is in full sunlight or near a heat source that could affect the temperature reading. If you rely on 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 fixing a dirty flame sensor to a pro like Robinson Service Experts.
When it involves heating and cooling equipment, larger isn’t always best. An oversized system warms up your residence too fast, causing intolerable temperature swings and short cycling. The only way to resolve this issue is to request new furnace installation.
