Steps to Take If Your Furnace Is Blowing Cold Air

When your furnace is blowing cold air, it’s not doing you any good. You’re likely wearing multiple layers, shivering, and losing money! On top of that, you’re more stressed because you’re thinking about the significant investment required for a new furnace.

But what if we told you a new furnace might not be needed? One way to know for sure is to call the professional HVAC furnace technicians at Rowland Air. We’re happy to come to take a look at your heating system. However, there may be a few steps you can take before making that phone call.

How to Tell If Your Furnace is Blowing Cold Air 

Many furnaces blow air across heating cools to make cold air warm. Then that air enters your home through air ducts to create a comfortable atmosphere. Keep the following signs in mind as they suggest that your furnace is blowing cold air:  

  • The furnace is blowing nonstop 
  • There are uneven heating spots throughout your home 
  • No heat is being produced 

Once you’ve determined a problem, you can begin taking the necessary steps to troubleshoot the issue.  

Troubleshooting a Furnace Blowing Cold Air   

You don’t need an explanation for why a furnace blowing cold air is a problem. However, you can complete a few easy steps to check why your furnace is blowing cold air. Resolving the issue may be as simple as pressing a button, and if so, that will save you from calling an HVAC technician for an emergency house call. 

Check the Thermostat Settings 

Before you automatically assume there’s a problem with your furnace, check your thermostat settings. The temperature may be lower than your desired temperature or switched to cooling mode. 

Ensure the thermostat is set on heating mode with the fan on auto. Keeping it on auto mode allows the heat to turn on automatically when your home drops below the desired temperature.

Examine the Vents 

Are your vents blocked or closed? Only open vents allow warm air to move throughout your house. When vents are blocked or closed, your furnace cannot provide air to every part of your house.

Inspect the Air Filter 

Over time, your air filter collects dirt and debris. If you aren’t performing routine maintenance and changing this filter, you’ll begin noticing problems with your heating system. 

A clogged filter prevents air from traveling through it and into the furnace for heating. This issue results in inadequate air to heat and redistribute throughout your home. For optimal efficiency, the pros at Rowland Air recommend changing your air filter at least once every three months.

Check the Fuel Supply 

If your furnace is blowing cold air, check the fuel supply. Should you detect a gas leak, turn the gas valve and heating system off, evacuate your home, and report the issue to your utility company. 

Remember, you should never use a lighter or matches around a furnace.
