Preparing for Common Issues with Furnaces During Winter

November 9, 2021

With winter right around the corner, it is important to be prepared for common furnace issues. We’ve put together some tips on how to recognize and troubleshoot these common furnace issues so you aren’t left out in the cold this winter season.

Carbon Monoxide Leaks

Carbon monoxide is odorless, tasteless, and lethal. If you have a carbon monoxide gas leak, it poses an imminent danger to your home. Whether you have a brand-new furnace or one that is a decade old, it is critical to install carbon monoxide detectors in your home.

Carbon monoxide leaks are more common in furnaces that are 10 to 15 years old. If you have a furnace that is ten or more years old, be sure to have your furnace inspected. You also want to make sure you have your HVAC system and furnace professionally serviced and maintained. Our team of HVAC professionals will check your furnace for cracks, leaks, and other issues, as well as adequate ventilation.

If your carbon monoxide detector goes off, call a professional immediately so they can find the leaks and properly repair your furnace.

Inefficient Heat/No Heat

If your furnace is not efficiently heating your home or is not warming it all, this could be caused by a variety of factors. The first thing we recommend checking is the thermostat. Check to make sure that it is working and has a fresh set of batteries. A faulty thermostat commonly causes a lack of heat.

For those who have a heat pump, it could be struggling due to the ice, snow, and frost that can accumulate. Check to make sure your heat pump has the proper defrost settings to keep the ice and frost from hindering the heat pump’s function. If there are no defrost settings, you will need to periodically clear the ice and snow manually.

With a furnace, you could be having issues with your pilot light. If the pilot light is out, check to see if there is a steady power source. If there is no steady power source, the assembly may be hindered by grime and gunk. Be sure to call a professional to have the assembly carefully cleaned out.

If you’ve checked and determined your pilot light is on, but you are still experiencing a lack of heat, there could be issues with your:

  • Gas valves
  • Main burners
  • Flame sensor
  • Control board

Clogged or Dirty Filters

If you’ve noticed that some rooms are colder than others or that air is not circulating properly, there could be several causes. One of the most common causes for poor air circulation or cold spots in the home is a clogged, dirty filter. This can cause the airways to become blocked, which in turn prevents your home from being efficiently heated.
Check your filters; if they are dirty or clogged, sure to replace them or clean them out for better heating power.

Heat Cycling

Is your heater turning on and off more than usual? This means you are having issues with heat cycling. This issue affects the efficiency of your furnace and can also cause a spike in your utility bills.

This can be caused by a dirty blower, filter, or a malfunctioning thermostat. You can try to resolve the issue by changing or cleaning your filter or checking your thermostat. Even if your system is providing enough heat, if you are experiencing heat cycling, you will want to call a professional to have the issue resolved.
