Why Does My Furnace Short Cycle?

As the weather gets cooler, it’s not unusual for your home’s heating system to operate more frequently. But when furnace cycles on and off repeatedly, your unit may have fallen victim to short cycling. We agree that this can seem like a major headache and something that you probably don’t feel like dealing with. However, Princeton Heating & Air Conditioning is here to help by offering affordable and fast furnace repair. South Brunswick NJ homeowners can get their furnace back in proper working condition quickly without having to break their bank account.

By repairing your short cycling furnace, you can…

avoid a whole slew of issues. This includes the untimely demise of your system and higher than necessary energy bills. However, what causes short cycling? How can you have the problem fixed? In this article, we will explore the common causes of a furnace that short cycles.

Improperly Sized HVAC System

When short cycling issues start occurring soon after installing a new heating system, the problem may be much more significant than you think. More often than not, such issues are caused by a unit that’s just too big for your home. As a result, the indoor air temperature rapidly fluctuates between hot and cold, causing the equipment to get stuck in a cycle of quick heating and cooling. Besides driving up your electricity bills, this can also shorten the lifespan of your system.

Although having a furnace that warms up the home quickly is something most homeowners wish for, having an efficient system always takes top priority. If your unit has always been affected by short cycling ever since it was installed, the technicians might have erred when measuring out your indoor space. Your best solution would be to get in touch with a reputable heating contractor for a proper load evaluation exercise.

Overheating

Your home’s heating system has a safety mechanism to monitor surrounding temperatures and shut the equipment down when there’s greater risk of overheating.
Short cycling often occurs when the heat exchanger gets too hot…

which causes the burner to switch off automatically. The presence of cracks in this component are also known to cause short cycling. This is something you don’t want to be dealing with.

You see, a cracked heat exchanger creates a channel through which carbon monoxide could leak into your home, resulting in an immediate risk to life. If you suspect that your short cycling issues may be as a result of overheating or a damaged heat exchanger, have the entire system checked by a professional sooner, rather than later. A licensed HVAC technician will be able to track the problem down and figure out what needs to be done to rectify it.

Other Causes

At times, short cycling problems are  caused by a faulty thermostat, rather than the unit itself. You might want to have yours tested to ensure it’s functioning properly. The placement of this device also makes a difference. When it’s too close to another source of heat, it registers incorrect readings. It, also, signals your heater to turn off as a result. Other potential causes of short cycling include:

• Clogged filters: A dirty unit can cause the accumulation of warm air within the unit. This would eventually signal the furnace to shut off. Make sure your air filters are always clean. Also, have a HVAC service company tune up your system from time to time.
• Corroded flame sensors: The presence of too much rust on the gas furnace’s flame sensor may prevent proper functioning. Furnace repairs involve flammable substances and high voltages. Therefore, you’re better off calling a professional as opposed to attempting to clean the sensor yourself.

It’s tempting to think that short cycling isn’t such a serious problem. This is especially true since the heat might still be working after all. When your furnace turns on and off too often, the unit’s motors, belts and other components are subjected to a huge amount of stress. As far as fixing the problem, you don’t want to have it done by an amateur. This is for some good reasons too. You want an an experienced professional. An amateur costs you time as they try to figure out the problem. They could also cause more damage in the process. You can save yourself lots of headaches by reaching out to an established HVAC company in your area.
