The Most Common Furnace Issues in Winter

Did you know that snow can fall at speeds of one to six feet per second? Winter is coming, and if your furnace isn’t up-to-date, staying warm this season will be challenging. 

Are you unsure whether or not your furnace needs a fix? You’re in luck! Read this guide on winter’s most common furnace issues to be prepared today. 

Uneven Airflow

If your furnace is not working, it might be due to blocked ducts and vents. Blocked ducts and vents cause uneven airflow. Blockages can lead to one room feeling cool while the other feels hot. 

Frozen Pipes

December, January, and February can see freezing temperatures in Branson. The average annual high is only 47 degrees in January, and the low is only 28 degrees. 

Daytime temperatures might be warmer, but pipes could freeze overnight. Temperature changes could lead to pressure buildup, which can cause burst pipes. 

Blowing Cold Air 

Blocked or dirty filters could cause your furnace to work harder, and you’ll spend more money. Ensure that you have regular furnace maintenance to avoid this. 

Filters need to be replaced or cleaned every 1-3 months. If it’s only blowing cold air you could have a problem with the air ducts. 

The Furnace Won’t Turn On

Proper maintenance and the age of your furnace will come into play. Check the thermostat to ensure the fan is set to auto and on heat. See if the circuit breaker has tripped. 

If it’s turning itself on and off, you might have a blocked filter, the wrong thermostat setting, or impeded airflow. You could also have a furnace leak. 

Flickering Pilot Lights

Damaged or clogged flame sensors can cause pilot lights to turn off. Replace or clean them right away. 

Drafts are the most common cause. Check the vent cover to ensure it’s attached properly. All drafts in the furnace room must be sealed to stop them. 

Carbon Monoxide

This deadly gas comes from the incomplete combustion of natural gas. Buy carbon monoxide detectors if you have natural gas appliances or furnaces. 

Carbon monoxide is odorless, which means it can go throughout your home without warning. Watch for a blocked chimney, flickering pilot light, or heating maintenance issue. 

Gas vs. Electric Furnaces

If you have a gas furnace and the blowers constantly turn, you might have a clogged heat exchanger. More fuel might be necessary to make up for the inefficient burning process. 

You might also have a bad blower or loose belt. An annual check will help prevent and diagnose any problems. 

For electric air furnaces, you might have insufficient heating that won’t reach your entire home. Clean your system and contact your local heating and cooling specialist.
