Your furnace keeps your family cozy during the frigid winter months, so it’s annoying when something is wrong. One frequent complaint is a furnace that continually turns on and turns off all the time. This problem is known as short cycling. It stresses your furnace and may result in costly repairs or even early breakdowns.
Short cycling can be the result of for varying reasons. Before you request furnace repair, research the likely causes and how to take care of the situation.
1. Filthy Air Filter
The HVAC filter traps airborne dust, hair and other debris that could damage the furnace. If you don’t replace the filter frequently, it can become filthy and reduce the airflow. When this occurs, a safety mechanism switches off the furnace to prevent getting too warm. Pull Out the filter, and if it’s dirty, get a new one. Going forward, change the filter every 30 to 90 days to keep your furnace from short cycling.
2. Blocked Air Vents
A dirty filter isn’t the only issue that can restrict airflow and overheat your furnace. Walk around your house and be on the lookout for for shut or obstructed air vents. For adequate system balance and performance, keep all registers open, even in empty rooms.
3. Dirty Blower Wheel
The furnace blower consists of blades that move air through the ductwork. If they are caked with dirt, the air won’t move properly, causing overheating and short cycling. Regularly putting in a new the filter is the simplest way to avoid 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 brain of your HVAC system and tells the furnace what to do. Double-check the thermostat is set to heating mode and auto fan with the desired temperature showing on the screen. Try putting in new batteries. Also, check whether the thermostat is in full sunlight or near a heat source that could affect the temperature reading. If you have a smart thermostat, go to 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 sense the flame if it’s coated in soot, so the gas switches off prematurely and the furnace turns off. Leave the adjustment of repairing a sooty flame sensor to a pro like Freschi Service Experts.
6. Oversized Furnace
When it involves heating and cooling equipment, oversized isn’t always better. A bigger system warms up your residence too rapidly, creating intolerable temperature changes and short cycling. The only way to resolve this issue is to request new furnace installation.
