When the temperature drops, you want your furnace working correctly to keep your home warm.

But what happens when it starts to switch off and on? This is called Short Cycling.

What Causes Short Cycling?

Short cycling refers to when your furnace frequently turns on and off, preventing it from keeping your home warm. Keep reading to check out the top 9 reasons why.

1. The Bad Flame Sensor

If your flame sensor isn't working, it won't sense a flame so will shut off your furnace. Keeping it clean will keep your furnace working in tip-top condition.

2. Overheating Furnace

Frequent overheating results in your furnace turning itself off to prevent potential damage. This is serious. Call an HVAC professional!

3. A Dirty Air Filter

A contaminated air filter prevents hot air from circulating throughout your home, resulting in short cycles and overheating. Replace it regularly.

4. Oversized Furnace

An oversized system can result in short cycling by unevenly distributing air. If this happens or your energy bills are higher than usual, check the size of your furnace.

5. Air Leaks

Insufficiently sealed windows and poor insulation prevent your furnace from producing enough air to heat your home correctly. Check your windows!

6. Clogged Exhaust Flue

Sometimes stuff can find its way into your exhaust flue. When the flue clogs, your furnace will shut down. Keep it clean and check it regularly.
