3 Reasons Your Furnace Is Short-Cycling

Does your furnace turn on, run for a few minutes, then shut off again, just to restart again a short while later? This is called short-cycling and it is a sign that something is not working correctly in your furnace. This constant starting and stopping causes more wear and tear on your furnace and will drive up your heating costs each month. There are a three common reasons for short-cycling – some easy to fix, others that are larger problems.

Thermostat Malfunction

One of the simplest reasons your furnace is short-cycling is a communication issue in your thermostat. If your thermostat is older, or just malfunctioning, replacing it could stop the short-cycling problem, lowering your energy bills and reducing wear on your furnace.

Overheating Issues

If the heat exchanger in your furnace is overheating, this can be the reason that the furnace turns off after just a short period, then restarts when it cools down. This can be a serious problem; it can cause cracks in the heat exchanger that can lead to carbon monoxide leaks in your home. However, it is usually caused by restricted air flow or a dirty filter, which can be easily fixed.

Your Furnace is Too Large

If you have a new furnace and short-cycling is occurring, your furnace may be too large for your home. Bigger is not always better – when purchasing a furnace, it should be right sized for your home or it can cause problems. A furnace that is too large will heat too quickly and often the air is not distributed properly, causing the unit to turn on and off more often.

If you are not sure what is causing your short-cycling problem, the best solution is to have your furnace inspected by a local HVAC service.

Keeping an Even Temperature in Your Home

Do you find that certain areas of your home are either colder or warmer than others? It could be a problem with your cooling or heating system. However, often it is a simple issue that you can fix or check on your own. Here are a few to things to check before you consider calling in a professional:

  • Check your air filter. Sometimes something as simple as a clogged air filter can cause inconsistencies in temperature. Check your air filter and change it if it looks dirty.
  • Inspect your air vents. Turn on your AC or heat and check the air coming from your vents or registers. Make sure all are open and allowing air through. If a vent is open but no air is coming out, you may have a blockage in an air duct.

If you check the vents and filters but still can’t resolve the uneven temperatures in your home, it may be time to contact your local HVAC service. You may have issues like blocked or leaking ductwork that is affecting the air flow. This is a common issue that can increase your energy bills and cause poor temperature control.

Has your home always been difficult to keep at an even temperature? If this isn’t a new problem, it could be the design of your home or the location of your thermostat. Your HVAC professional can evaluate your system and offer solutions. Adding a zoning system, a ductless mini split or just moving the thermostat could fix your issue. The professionals will get to the heart of the issue and find a solution for improved comfort and efficiency in your home.
