Why Is My Furnace Short-Cycling?

Why Is My Furnace Short-Cycling?

Why Is My Furnace Short-Cycling?

Most of us are familiar with the little tick sound that the furnace will make when it starts a new cycle, but if you are constantly hearing that sound, and noticing your system keeps turning on and off, you most likely have a short-cycling problem. Short-cycling can cause damage to your heating system, so it’s important to have the issue addressed right away. There can be a few reasons why your furnace is short-cycling, which is why it’s best to call for professional help. John’s Refrigeration has been helping customers in Mesa, AZ with their heating needs since 1970, so if you are experiencing issues with your furnace, call us today.

Reasons for Short-Cycling

Here are some of the reasons your furnace may be short-cycling:

Blocked Air Flow

Proper airflow is critical to the operation of your furnace. Airflow can be restricted by obstructed ductwork, a dirty air filter and/or blocked registers. To help prevent low airflow, it’s important to change your air filter regularly (approximately every 3 months), have your ductwork professionally cleaned every 3-5 years and make sure that furniture, drapes, etc., are not blocking the heat registers in your home.

Thermostat Problems

Your thermostat controls when your system cycles; should it malfunction, one of the problems that can develop is short-cycling. Common issues that can cause the thermostat to perform poorly are dirt and dust on the inside instrumentation, placement in drafty areas or poor mounting that makes the thermostat hang unevenly.

Overheating

Your furnace has a number of safety devices that will turn it off when it gets too hot. One of the reasons short cycling can occur is because the heat exchanger overheats. When this happens, the burner automatically shuts off to prevent damage to the heat exchanger.  In rare circumstances, a crack in the heat exchanger can also cause short cycling. Significant dirt and dust can also cause overheating, as a thick enough layer will act as insulation and keep heat trapped, which makes the heat exchanger too hot. No matter what the cause, overheating is a serious situation, and should be taken care of immediately.

Short-cycling can cause premature aging, wear and tear and damage to your furnace. If your heating system is short-cycling, call John’s Refrigeration today and schedule your heating service in Mesa, AZwith one of our HVAC professionals.
