A furnace blowing cold air doesn’t do you any good. There’s nothing more frustrating than coming home to your living room feeling like an icebox. Still, it’s a common problem that indicates you’ll need to pay close attention to your furnace’s behavior.
Understanding why the problem happens helps you determine whether you need to adjust your maintenance routine or call for a professional furnace repair company.
Could Simple Problems Be Causing the Furnace to Blow Cold Air?
You’d be surprised by just how often something as simple as your thermostat is the cause of your cool air. Many homeowners switch up their settings around this time of year, hoping to make their home more comfortable, but accidentally do the opposite.
A good example would be setting the fan to run continuously. This means when the furnace isn’t active, the blower fan is running constantly, making the air feel cooler. Switching this from “on” to “auto” is a quick fix.
Another common and simple issue is a clogged air filter. The dirt restricts airflow and could even cause the furnace to overheat, triggering an automatic shutdown and leaving the fan to push around cooled air.
It’s vital to clean your air filter and check your thermostat settings before contacting a furnace repair company.
What Are the Serious Problems That Require a Furnace Repair Company?
While you can sometimes fix a furnace that’s blowing cold air with a few tweaks, it could also signify more complex issues that require a professional.
If you have an older gas furnace, the issue could be the pilot light going out. This prevents the main burners from producing heat, causing the unit to push lukewarm or cool air out.
Newer electronic furnaces might have a dirty or damaged flame sensor. This often causes the system to malfunction, usually pushing warm air at first before pushing cool air.
Another major cause could involve the gas supply or other safety mechanisms, similar to the ones that shut the system down when you have a clogged filter. However, the shutdown is caused by a damaged component rather than an unclean one, so you’ll need to contact a furnace repair company to fix this issue.
These are all serious problems that require prompt furnace repair to keep your home safe and your unit healthy. However, the most serious is a cracked heat exchanger, which could cause harmful carbon monoxide to leak into your home.
Since the issue can range from minor to severe, the best way to know exactly why your furnace is blowing cold air is with a professional inspection. Contact them if you’ve already checked your filter and thermostat settings but still have cold air coming from your vents.
