When the winter air comes streaming into the Triangle area, the last thing that you want to feel is cold air coming from your furnace. You want to stay warm through the winter, and the only way it can happen is if your electric or gas furnace operates at maximum efficiency. If your furnace blows cold air, taking care of the problem quickly ensures a warmer and more comfortable interior from winter until spring.
5 Reasons Your Furnace Blows Cold Air
- The circuit breaker tripped.
An electric furnace has its own dedicated circuit in the electrical panel. Check to see whether or not the circuit has tripped. If so, flip the switch to the on position, and contact a professional if the problem persists.
- The air filters have degraded.
Clogged air return filters can prevent your furnace from operating efficiently. Check the filters for dirt, debris or other contaminants that may cause problems. You can clean the filters or replace them to create better airflow and fill your home with warm air.
- The furnace door is open.
It’s common for homeowners to leave the furnace door open without knowing it. If you notice cold air coming from the vents, check the furnace door. Even the slightest door crack can reduce the amount of warm air that flows through the vents.
- The pilot light went out.
You’ll lose heat when the pilot light goes out, so check for the blue flame in your gas furnace. If you notice a yellow or orange flame, it could indicate a problem and require professional assistance. Some gas furnaces don’t have pilot lights; instead, they have electric ignition systems. These systems need replacement after a few years, so keep that in mind if you don’t see a blue flame and have an electric ignition.
- The oil levels are low.
An oil furnace will continue to provide heat as long as it has fuel. Once the oil runs out, the unit will stop working. Make sure that you have plenty of oil left in the tank if your furnace is blowing cold air.
When your HVAC system fails to perform its best, contact Rapid Repair Experts to help remedy the problem and reduce future malfunctions. In many cases, simply checking the thermostat or restarting the pilot light is enough to get the furnace blowing warm air again. If all else fails, calling a professional can provide quick action and give you peace of mind.
