How to Fix Your Furnace's Short Cycling Problem and Save Money

Does your furnace run for a few minutes, then shut off for a few minutes, only to start again? Is this starting to make your energy bill skyrocket? If so, then you may be experiencing a potentially dangerous condition known as short cycling. In this long and comprehensive article, we will dive deep into the furnace short cycling problem and cover the causes, consequences and methods to use in order to fix it.

Having a working knowledge on how to identify, troubleshoot and fix short cycling can help you keep your home safe and save you money on your utility bills.

What is Furnace Short Cycling?

Furnace short cycling is a term describing when a furnace repeatedly cycles on and off in quick succession in order to regulate the temperature in a home or office. This rapid firing can hamper the efficiency of the entire system, leading to a spike in energy costs and a lack of comfort in a home.

Furnaces are designed to be comfortable and efficient. When there is an issue like short cycling, it can create an environment that is neither comfortable nor energy efficient. Short cycling occurs when a furnace always starts again, even when it hasn’t cooled down enough. This inefficiency can significantly increase energy costs.

Causes of Furnace Short Cycling

The most common cause of furnace short cycling is an insufficient amount of fuel being supplied to the unit. In many cases, this is due to an excessively sized furnace being installed, which leads to the demand for fuel being too high for the supply to match.

Other causes of short cycling include an oversized or clogged air filter, blocked air intakes, blocked or faulty flue, damaged heat exchanger, incorrect thermostat settings, or broken components such as fan motors and relays.

What are the Consequences of Furnace Short Cycling?

Short cycling can cause a variety of problems including dangerously high levels of carbon monoxide, unnecessarily high energy bills, fires, and safety hazards. In order to ensure the safety of your home and family, it is important to identify and fix furnace short cycling as soon as possible.

How to Fix Your Furnace's Short Cycling Problem

Take Care of Obvious Issues:

It’s important to inspect the furnace’s air intake and exhaust vents prior to performing any work. Air obstructions and clogged parts can cause furnace short cycling, so it’s important to check for any signs of debris, dirt, or obstructions.

Evaluate the Size of Your Furnace:

If your furnace is too large for the space it’s heating, it can lead to short cycling. An HVAC contractor can help you determine the size best suited for your space and install it if necessary.

Inspect the Heat Exchanger:

A damaged heat exchanger can cause short cycling, and it must be replaced immediately. A professional should be able to identify this issue and provide a replacement.

Check the Thermostat:

Thermostats often contain sensors that measure the temperature of a room or area. If these sensors are not properly calibrated, they can cause the furnace to shut off too early, leading to short cycling.

The thermostat’s software can sometimes be tweaked to correct any issues that may be causing the issue. If that doesn’t work, it may be time to invest in a new one.

Inspect Fan Motors and Relays:

Another potential cause of short cycling is a broken or malfunctioning fan motor or relay. These parts should be inspected regularly in order to prevent any issues.

If the fan motor or relay appears to be faulty, it should be serviced or replaced as soon as possible. A professional HVAC technician can help you diagnose these problems and provide the necessary repairs.

Conclusion

Furnace short cycling can be an expensive and dangerous issue. It is important to be aware of the causes and consequences of the issue in order to keep your home safe and your energy bills low. If you believe you are experiencing furnace short cycling, then it is important to contact a professional HVAC contractor as soon as possible to inspect your unit.

Furnace Short Cycling

Preventive action to avoid Furnace Short Cycling can help maintain adequate temperatures in your home and make sure your furnace is working safely and efficiently. Following manufacturer recommendations and local appliance or HVAC technician’s recommendations is the best way to make sure your furnace does not suffer from short cycling issues.

PLEASE consider the following tips when it comes to preventive action against Furnace Short Cycling:

• Check and clean your filter – Dust, pet hair and dirt build up can restrict air flow, causing your system to overheat. Clean your filter every couple of months and/or check it often to make sure it is not clogged.

• Replace a dirty flame sensor – Just like the air filter, a dirty flame sensor can also cause a furnace to short cycle. Make sure to regularly clean the flame sensor and understand how to test if it is working properly.

• Inspect the blower for clogs – Debris can build up in the blower and cause it to overheat and result in short cycling. It is important to regularly clean the blower motor to make sure it is working properly.

• Monitor the air flow of the system – The air flow of your system is important to make sure it operates efficiently. If the air flow is blocked or restricted in any way, it can cause the system to short cycle. Make sure to adjust the air flow accordingly when necessary.

• Check the thermostat – If the thermostat is not set properly it can cause your system to overheat and short cycle. Make sure to periodically check the thermostat and make sure it is set properly for optimal performance.

• Schedule professional maintenance – Schedule preventive maintenance with a professional HVAC technician to make sure your system is operating properly and identify any potential problems before they become an issue.

Following these tips and working with a professional HVAC technician to inspect your system regularly can help prevent any Furnace Short Cycling issues and maintain a safe and efficient system.
