Your furnace keeps your house warm during the frigid winter months, so it’s disconcerting when something is off. One common issue is a furnace that continuously turns on and turns off again. This problem is known as short cycling. It stresses your heating system and could lead to expensive repairs or even early failure.
Short cycling can be the result of for varying reasons. Before you book furnace repair, research the possible causes and how to resolve the situation.
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 turns off the furnace to stop overheating. Inspect 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 reduce airflow and overheat your furnace. Walk around your house and look for shut or crowded 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 dirty, the air won’t move correctly, leading to overheating and short cycling. Frequently putting in a new the filter is the simplest approach to avoid a dirty blower wheel. If the blades are already dirty, book furnace maintenance to have them cleaned.
Check your thermostat next. This is the core of your HVAC system and instructs the furnace on what to do. Double-check 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 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.
