Common Furnace Issues: How to Identify and Fix Them

Furnace problems can be annoying and potentially dangerous. Fortunately, regular maintenance and proper attention can prevent most common furnace issues and help you avoid costly repairs. Some common issues include dirty filters, thermostat problems, and pilot light issues.

Dirty Filters

One of the most common issues with furnaces is the need to provide more airflow. A dirty filter restricts airflow, making your furnace work harder and using more energy to keep your home warm. Dirty filters will also cause your furnace to wear out much more quickly. Changing or cleaning your furnace filter regularly, according to the manufacturer’s recommendations, is essential. This prevents debris from collecting on the filter and blocking the airflow.

Thermostat Issues

Most furnaces are controlled by a thermostat that regulates the warm air coming out of the appliance. If your thermostat does not work correctly, the indoor temperature will be too hot or too cold. A malfunctioning thermostat can cause your furnace to work harder and use more energy to heat your home, leading to higher energy bills. It can also shorten the lifespan of your furnace if left unattended for long.

Fortunately, thermostats are relatively easy to check and replace if necessary. First, make sure your thermostat is plugged in and turned on. Then, check the settings. If you cannot adjust the settings, you may need to replace the thermostat.

Pilot Light Issues

A pilot light ignites the furnace when it is turned on. Knowing how to repair and maintain your furnace can help you avoid pilot light issues. If your pilot light does not work, your furnace will not start running. Since fixing the pilot light can be complicated, it’s best to call a qualified professional to investigate the problem. They will know how to resolve any issues with the furnace.

Uneven Heating or Lack of Heat

Uneven heating is a problem that many people have. The most common reason for uneven heating in your home is the lack of airflow. Dirty filters can cause a lack of airflow, a blocked intake vent, and thermostat issues. You can check your furnace filters and vents to see if they are blocked. If they’re working correctly and you still have uneven heating, call a professional to check your system and diagnose the problem. Even better, regular maintenance can prevent the problem from occurring in the first place.

Your family and your home will feel warmer and safer if you take the time to maintain your furnace correctly. If you need furnace repair or replacement in Clinton Township, MI, contact our experts at North Wind Heating & Air Conditioning.
