How To Know If Your Furnace Is Short CyclingA furnace that is working properly will start running and continue to do so up until it reaches the temperature you want. It will then immediately turn off, allowing the desired temperature to be maintained. When the temperature begins to fall, it will start running again, and continue with that process all throughout the day and night. However, if the furnace develops a short-cycling problem, it will basically be turning on and off repeatedly in quick sequences. It will not get to the desired heat levels. The turning on and off sequences will eventually result in the wear and tear of the unit. Furthermore, even though the furnace will be on, your home will be far from warm.What Causes Furnace Short Cycling?![]() 1. OverheatingHVAC units have in-built components that protect them from damage. The purpose of a home furnace is to provide warmth, but it can actually get too hot. If a dangerous level of heat is reached, the furnace will immediately turn itself off. If it does not switch off immediately, cracks can form in the heat exchanger and dangerous carbon monoxide can start to leak. So, in a sense, shutting off right away when it starts to overheat is actually a good thing. Overheating is usually a result of airflow blockages caused by congested exhaust vents and filthy air filters.2. A Defective Flame Sensor![]() 3. Blocked Heat GratesA furnace works by warming up the air and then pushing that air out through the heat grates. If the grates are blocked, the air will not be able to flow outside the grates. The trapped air will eventually cause the unit to overheat. As long as that problem is not fixed, the system will continue to short-cycle. These heat grates also have a control device called a damper which lets you control the temperature in your home. This actually helps to save energy. Also, make sure that you do not close too many vents as this can also cause the system to overheat; 75% or more of the vents should always be open.

Blocked Exhaust VentIn order for your heating system to work effectively, the exhaust vents must be kept open at all times. But they can be blocked by things such as snow, vegetation, and nests, among other things. Make sure that these blockages are removed on a regular basis. It can also happen that a dangerous animal can actually block the opening of the vents. If that is the case, make sure that you contact an animal control expert to deal with the situation.

The Furnace Is Too BigYou might think that getting a big furnace will give you more value for your money as it will probably offer more when compared to a smaller one. However, this is not the case; you might actually have a furnace that is too big for the house you live in. A bigger than required heating unit will result in excess capacity, and this can cause short-cycling. The wear and tear of different parts of the unit will happen much quicker, temperature fluctuations will be more noticeable, and you will have an increased energy bill. Although it might cost you quite a lot of money, the best solution in this instance is to have a technician install a new furnace which will be the ideal size for your heating needs.ConclusionTaking care of any issues that your furnace might have early will result in you having a comfortable winter. The moment you detect short-cycling, try, and figure out the reason for that based on the points discussed above. An experienced HVAC technician will be able to give you an accurate diagnosis and a lasting solution.Give Lawes Company A Call For All Of Your HVAC Needs![]() via Lawes Company - Feed https://www.lawescompany.com/furnace-runs-then-shuts-off-and-starts-again/ Comments are closed.
