Is a Broken Heater the Cause of Cold Air Blowing From the Vents?

Most people who have lived in Michigan for over a year can attest to the fact that winters in the state are pretty cold! The last thing people want is to have a broken heater in the dead of winter. So when cold air starts blowing out of the vents throughout the house, most homeowners start to get nervous. Could it be a broken heater, or is there something else going on? Well, it could be either.

But with just a few quick checks, homeowners can determine what the issue is and whether they can fix it themselves or need to call a professional HVAC technician for assistance in getting things back up and running.

Check 1: Are the Furnace Settings Correct?

When the heater starts blowing cold air, the first thing to check is the furnace settings. How is the fan setting programmed? The fan controls the blower, and the blower circulates air throughout the house. If the fan is set to “on,” the blower will run all of the time, even if the furnace is not heating air. This is a common reason for those random blasts of cold air.

By simply changing the fan setting to “auto,” the blower will only run when the air is being heated. Also, check the pilot light. The furnace’s burners won’t light when the light is off, which means no heat will be produced. Relighting the pilot light will fix this issue. Checking the furnace settings is something that a homeowner can do without a professional. All they need to do is a little bit of troubleshooting.

Check 2: Are There Dirty Air Filters That Need to Be Switched?

Dust and dirt collect on air filters over time preventing warm air from making its way through the house and instead allowing cold air to blow.

Many people wonder how often air filters need to be changed. Thinner filters, such as 1-inch or 2-inch filters, need to be switched out about every 3 months. As the filters get thicker, the less often they need to be changed.

A 4-inch filter should be changed every 6 months, and a 5-inch filter only needs to be changed once a year. Changing them regularly can also assure you that there is purified air inside your home.

Check 3: Is it an Overheated Heater?

This is the problem that people fear: a broken, overheated heater. When a heater is overheated, it can no longer function properly. There are several tell-tale signs of an overheated heater, and one of them is cold air blowing out of the heater.

There are a few other signs to pay attention to including a burning smell from the vents, loud humming noises, or a complete shutdown of the furnace. In this situation, it’s best to contact an HVAC professional as the heater will likely need to be replaced.
