Improperly Sized HVAC System

furnace short cyclesWhen you notice that your furnace kicks on and off constantly shortly after you installed it…

then this is a major problem. This is because you probably got a unit that is far too big for your home. This causes indoor air temperatures to fluctuate between cold and hot. When this happens, the system gets stuck in a heating and cooling cycle, which can drive up energy costs and shorten the lifespan of the system.

Many people love the idea of having a furnace that heats the home quickly. However, efficiency is far more important. When a newly installed system short cycles, then the problem is caused by an improper installation. You’ll want to hire a reputable heating contractor to fix the issue. They will inspect your heater and provide you with all of your solutions.

Overheating Issues

Your heater has a safety feature that monitors the surrounding temperatures and shuts itself off when there is a risk of overheating. However, when the heat exchanger gets too hot, short cycling occurs. This leads to the burner switching off automatically. Cracks that are present in this component cause short cycling.

A cracked heat exchanger causes carbon monoxide to leak into your home. This poses a serious risk to your health and life. When a heat exchanger is damaged or a unit is overheating, contact a professional HVAC technician right away. You will want to take care of this problem as soon as possible.

Other Causes Of Your Heater Short Cycling

For example, it registers improper readings when it is close to a source of heat. Consequently, the thermostat will signal your heater to turn off and on.

When your unit is too dirty, then it accumulates warm air inside the unit. This will cause the furnace to prematurely shut off. Always clean the air filters because this can solve the issue. It is best to check them on a monthly basis and replace them when they are dirty. This can prevent an issue like this and it also ensures much more efficient operation. An HVAC technician should also tune up your heating system on an annual basis.

Corroded flame sensors also cause short cycling. When there is too much rust on the sensor, then your heater will not function properly. This requires repairs. Make sure to use a professional. Heating systems have high voltage and flammable substances which is something that makes it a job for a professional contractor.
