Your furnace keeps your house warm during the frigid winter months, so it’s frustrating 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 might cause costly 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 attracts airborne dust, hair and other substances that could wreak havoc on furnace. If you don’t get a new 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, 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 obstructed air vents. For adequate 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, creating overheating and short cycling. Routinely 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 core of your HVAC system and tells the furnace what to do. Ensure the thermostat is on 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 turns off sooner and the furnace shuts off. Leave the work of repairing a dirty flame sensor to an Expert like Parker Pearce Service Experts.
When it involves heating and cooling equipment, larger isn’t always better. A larger system adds warmth to your home too fast, creating uncomfortable temperature changes and short cycling. The only way to resolve this issue is to request new furnace installation.
