Why Is My Furnace Blowing Cold Air?
If your furnace is blowing cold air, you know how frustrating it can be. It can also be extremely uncomfortable and even dangerous for yourself as well as children and pets. Continue reading to discover some of the common causes of a furnace blowing cold air as well as some simple steps you can take to find a solution. For any larger issues with your heating system, the heating experts at Van Natta are only a call or a click away.
Make Sure Your Thermostat Is Working Properly
It may sound like common sense, but one of the most frequent heating problems is an incorrectly programmed thermostat. If your furnace is running but is only blowing cold air, it may be because the fan is set to ON. Regardless of the set temperature, the fan will continue to run and blow cool air if it is switched to ON. If this turns out to be the issue with your system, turn your thermostat's fan setting to AUTO and the fan will only blow warm air.
Your Furnace Overheated
What should you do if your furnace was working for a short period of time, then began to blow cold air, and finally shut off completely? This is a sure sign that your furnace has overheated. One of the most common causes of an overheated furnace is a dirty air filter. An air filter that hasn't been changed in a while can block airflow, causing your furnace to run longer and to overheat. Try changing your air filters to see if your furnace once again begins blowing warm air.
Problem With Your Pilot Light
Aside from the above easy fixes, there may be a more serious issue with your pilot light if your home is heated with gas. The first solution to try is simply relighting the pilot light. If it stays on, your furnace may begin working properly again.
If the pilot light does not stay on, there may be a problem with the gas flowing into the furnace. Make sure the gas valve switch is in the ON position. Another solution is to clean the pilot light if it is dirty. Sometimes a build up of dirt or dust could block the flow of gas entering the furnace.
If none of the above solutions work for you, there may be another more serious problem with your heating system. There may be an inadequate supply of gas or you have major duct problems that are allowing warm air to escape before it reaches the areas of your home where you need it to be.
