Does your furnace cycle on and off intermittently even when the weather is not extremely cold? If so, you may be concerned about whether it is malfunctioning. You also likely have concerns about whether or not the repetitive cycling is driving up your heating costs. The following points represent common reasons that consumers experience this phenomenon.
The cycling issues may be due to efficiency issues if you have not had your furnace serviced in a while. Dust accumulation or faulty components could be negatively impacting the furnace's performance. During servicing, important tasks such as oiling certain moving components and cleaning away dust accumulation ensures optimal efficiency.
Age of Furnace
If you have an old furnace, it is possible that the cycling issue is related to the furnace nearing the end of its service days. Do not make the mistake of thinking that an older furnace that is still distributing hot air does not need to be replaced. Also, keep in mind that upgrading an older furnace may improve your energy efficiency.
Air Filter Issue
Simply changing your air filter could improve furnace cycling issues. Your furnace requires proper filtration to operate. If it has been more than a month since you changed your furnace filter, this could be the cause of cycling issues. Even if you have a filter that is supposed to be able to endure a few months of use, it is possible that it is clogged with dust and debris if your furnace has dusty components.
A faulty thermostat could be the culprit, which would require a professional repair or replacement. Your thermostat could be faulty due to its age or it may need to be replaced due to being broken.
You may also be having thermostat issues due to your heat settings. For example, if you have the thermostat turned up to its highest temperature during the brink of winter, it may cycle on and off more often due to attempting to maintain a high internal temperature despite freezing temperatures. Try adjusting the temperature to a lower yet comfortable temperature to remedy this type of thermostat-related issue.
An HVAC contractor is the best resource to use to determine the exact reason your furnace is cycling at a questionable frequency. Based on their analysis, they can offer you advice on how to remedy the issue. For example, the issue could be maintenance related and a professional tune-up could correct the problem.
