A furnace that keeps turning on and off, a problem called short cycling, can be frustrating. It wastes energy and doesn’t heat your Bethel Park, PA home well. Let’s look at some common reasons why your home’s furnace might be short cycling.
Dirty Air Filter
A dirty air filter restricts airflow, and this restriction can make your furnace overheat. The furnace will shut off as a safety measure in response. Change your filter regularly to prevent this.
Oversized Furnace
A furnace that’s too big for your home heats the space too quickly, getting your home to the correct temperature and shutting off early. This can lead to uneven temperatures and excess humidity.
A properly sized furnace runs more efficiently and maintains a consistent temperature. This is why it is so critical that you consult with our heating specialists when choosing a new system for your home.
Faulty Flame Sensor
The flame sensor detects the flame in your furnace. If it’s dirty or faulty, it might incorrectly signal that there’s no flame. This causes the furnace to shut off.
In this scenario, call our pros for help. Our technicians can clean or replace the flame sensor and restore your furnace to working order.
Thermostat Problems
A malfunctioning thermostat can cause short cycling. It might not accurately read the temperature. This makes the furnace turn on and off at the wrong times.
Try replacing the batteries in your thermostat first, as sometimes it’s the simplest solution. If the issue is with wiring, you may need to call an electrician.
Restricted Airflow (Vents and Ducts)
Blocked vents or ductwork restrict airflow. This causes the furnace to overheat. Make sure your vents are open, and nothing blocks them. Call our professionals to check for crushed or disconnected ducts, which can affect system performance.
If your furnace short cycles, get help without delay. You don’t have to allow this problem to impact your comfort. Call Denillo Heating & Cooling for furnace repair or maintenance so that you and your family can continue to be cozy during the cold weather.
