Your furnace keeps your home cozy during the chilly winter months, so it’s annoying when something is wrong. One common situation is a furnace that endlessly kicks on and switches off again. This issue is referred to as short cycling. It stresses your furnace and might lead to expensive repairs or even early breakdowns.
Short cycling can happen for varying reasons. Before you book furnace repair, consider the probable causes and how to resolve the situation.
1. Clogged Air Filter
The HVAC filter catches airborne dust, hair and other pollutants that could cause problems for furnace. If you don’t replace the filter frequently, it can get filthy and reduce the airflow. When this happens, a safety mechanism shuts off the furnace to avoid getting too warm. Pull Out the filter, and if it’s dirty, replace it. From now on, install a new filter every 30 to 90 days to prevent your furnace from short cycling.
2. Clogged Air Vents
A dirty filter isn’t the only thing that can reduce airflow and overheat your furnace. Walk around your home and be on the lookout for for unopened or crowded air vents. For adequate system balance and performance, keep all registers open, even in unoccupied rooms.
3. Dirty Blower Wheel
The furnace blower has blades that move air through the ductwork. If they are dirty, the air won’t move right, creating overheating and short cycling. Routinely putting in a new the filter is the easiest approach to prevent a dirty blower wheel. If the blades are already dirty, request furnace maintenance to have them cleaned.
4. Faulty Thermostat
Examine your thermostat next. This is the core 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 displayed on the screen. Try changing the batteries. Also, check whether the thermostat is in full sunlight or near a heat source that could impact the temperature reading. If you rely on a smart thermostat, check the manufacturer’s site for troubleshooting instructions.
5. Dirty Flame Sensor
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 switches off too soon and the furnace shuts down. Leave the job of cleaning a sooty flame sensor to a pro like Teays Valley Service Experts.
6. Oversized Furnace
When it includes heating and cooling equipment, oversized isn’t always right. An oversized system warms up your house too fast, leading to uncomfortable temperature swings and short cycling. The only way to resolve this situation is to request new furnace installation.
