Your furnace keeps your house cozy during the frigid winter months, so it’s disconcerting when something is off. One frequent issue is a furnace that continually turns on and turns off again. This problem is called short cycling. It stresses your furnace and may result in expensive repairs or even earlier than normal breakdowns.
Short cycling can happen for a few reasons. Before you request furnace repair, research the possible causes and how to resolve the situation.
The HVAC filter catches airborne dust, hair and other substances that could wreak havoc on furnace. If you don’t replace the filter often enough, it can get clogged and decrease the airflow. When this occurs, a safety mechanism switches off the furnace to avoid overheating. 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 shut 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 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. Ensure the thermostat is in heating mode and auto fan with the desired temperature showing on the screen. Try changing the batteries. Also, check whether the thermostat is in full sunlight or near a heat source that could affect the temperature reading. If you use a smart thermostat, go to the manufacturer’s site for troubleshooting instructions.
The flame sensor switches off the gas valve when no burner flame going. The sensor can’t find the flame if it’s coated in soot, so the gas switches off sooner and the furnace shuts off. Leave the work of fixing a dirty flame sensor to an Expert like Comfort Masters Service Experts.
When it involves heating and cooling equipment, larger isn’t always best. An oversized system warms up your residence too fast, leading to uncomfortable temperature changes and short cycling. The only way to resolve this situation is to request new furnace installation.
