Keeping your home warm will help you stay well this winter. That is why it is very important to have a well-functioning furnace system. However, forgetting to schedule a fall checkup and repair can set your furnace to fail in winter. That could leave you with a furnace blowing cold air in the middle of the cold season.
Having a furnace that is blowing cold air is a major concern as it can cause health problems among your family members. To help you find the right solution to the problem, you need to identify its main cause first.
Here are 4 possible reasons why your furnace is blowing cold air.

The Thermostat is not Working.
Before calling in the pros, check your thermostat for any issue. Fixing a furnace that is blowing cold air can sometimes be as simple as adjusting the thermostat. Thermostats control the operation of your heating system. When the smart home device is switched off or has a low battery, it can negatively affect your furnace.
The air Filter is Clogged with dirt and Dust.
When was the last time you cleaned your furnace air filters? Over time, your air filters accumulate a great amount of dust and dirt, thus restricting airflow. That can force your heating equipment to work harder and overheat. When your furnace overheats, it shuts down the burner, which can be the reason why the equipment is no longer blowing hot air. Try washing the dirty air filters or replace with a clean one.
There are Leaks in the Ducts.
A duct leak is one of the potential reasons why your furnace is not blowing enough warm air. When there are leaks in the ducts, cold air in crawl spaces can get sucked into the ducts and delivered to your indoor spaces. Aside from the inconvenience, leaky ductwork can also cause your heating bill to skyrocket. Fix the furnace issue by locating the leaks and sealing them with HVAC tape or duct sealant. Depending on how extensive the leaks are, you may require help from a professional contractor to make sure the problem will not come back.
There is a Problem with the Fuel Source.
If you are using gas or oil as your furnace fuel source, make sure you do not run out of it during the cold winter months. Without a fuel source, the burner will not turn on, causing your furnace to blow or circulate cold air into your home. Check to see if your fuel supply is turned off by calling your provider. If your gas source is not the problem, you need to call a heating expert right away to inspect the system.
