Frequent Cycling

If your heating systems go on short cycles more often than usual, this could mean a bigger problem. It’s either your furnace is too big for your space, or your thermostat has malfunctioned. The heat cycling issue of your heating system raises your energy bills and wears down the unit’s components. So, make sure you have the right size furnace and your thermostat is working properly.

Insufficient Heat

Furnaces are designed to provide warmth and comfort during the cold season. But if you’re getting chilly and freezing toes, this means that a few issues are at play. The main power is turned off due to burnt fuse or a tripped circuit breaker. Other reasons could be a defective igniter, insufficient fuel, or clogged filters. Any of these issues can be the culprit of a system that is not working. It is best to have an expert technician to diagnose the problem and fix it quickly.

Gas Leaks

Should you be worried if you notice unpleasant odors coming from your furnace? Definitely! Especially when it smells like rotten eggs or burning plastic, this a red flag that there’s a bigger problem in your heating equipment that requires immediate attention. Avoid lighting matches that can cause fire or explosion. Evacuate your home immediately, and call 911! To prevent this scary situation, here are some ways you can minimize the risk from gas leaks:
  • Install carbon monoxide detectors
  • Check your heater regularly
  • Have an annual heating system tune-up
  • Avoid DIY furnace repair

Airflow Problems

Airflow problems may arise if your heating system is not maintained regularly. Your indoor air can be compromised when your furnace’s filters, fan motors, and air ducts are neglected. This can also cause your unit to overheat and reduce its efficiency level. To avoid this issue, regular maintenance of your heater is the key. That means replacing your air filters frequently and hiring qualified professionals to inspect, clean, and fix your system.

Thermostat Issues

The thermostat controls your system’s operation. When it fails to work correctly, your heating equipment won’t function properly. So, make sure to set your thermostat to “heat” and replace the batteries if necessary. You may also consider upgrading to a programmable model that is more accurate and convenient.
