Your furnace keeps your house warm during the chilly winter months, so it’s frustrating when something is off. One routine complaint is a furnace that continually turns on and turns off over and over. This problem is known as short cycling. It stresses your heating system and may result in pricey repairs or even early breakdowns.
Short cycling can be the result of for a few reasons. Before you schedule 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 get a new filter often enough, it can get clogged and decrease the airflow. When this occurs, a safety mechanism switches off the furnace to avoid getting too warm. 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 blocked air vents. For recommended system balance and performance, keep all registers open, even in unoccupied rooms.
The furnace blower has blades that push air through the ductwork. If they are covered in dirt, the air won’t move correctly, causing overheating and short cycling. Frequently putting in a new the filter is the simplest method to avoid a dirty blower wheel. If the blades are already dirty, schedule 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 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 guides.
The flame sensor is responsible for turning 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 cleaning a faulty flame sensor to a pro like Neal Harris Service Experts.
When it involves heating and cooling equipment, larger isn’t always right. An oversized system warms up your house too fast, causing unpleasant temperature swings and short cycling. The only way to resolve this situation is to request new furnace installation.
