Tips for Investigating a Cold Air Blowing Issue with Your Heater

Posted on: 6 December 2018

Now that the cold weather has started to come through in full force, you may be looking at your heating system and making sure it is functioning properly. However, if you notice that the heater is blowing cold air instead of warm air, then this is certainly a problem that needs to be addressed as soon as possible. In this situation, there are a few things you should do. Keep reading to learn more.

Look at Your Thermostat 

If you have just turned on your heater for the season, then there may be a simple solution to your cold air problem. It is possible that your thermostat is set to cool or fan instead of heat. And, in this case, the unit is working as intended and in accordance with how you have the device set. First, take a look at your thermostat to make sure it is set to heat instead of cool.

Also, once the thermostat is set to heat, you want to make sure that it is turning on when it is supposed to. Turn off your thermostat and then on again, making sure that the temperature setting is higher than the ambient temperature in your house. You should hear the thermostat click as it engages and turns your heater on. If it does not, then invest in a new thermostat and test the new one after it is installed.

Investigate Your Fuel

The problem you are having may have nothing to do with the furnace itself, but with your fuel source. For example, if you have a gas furnace and the gas company is doing maintenance, then fuel will not be moving through your fuel line. Your furnace also may not be able to light if there is a reduction in the flow of the fuel. So, you want to consider this; look to see if your pilot light is on and speak with the gas company if it is not.

If you have an oil boiler system, then you want to check to see if there is any oil in your oil tank. Also, consider cleaning out the fuel filter because a dirty one will prevent oil from moving to the boiler and allowing it to start. 

If you have an electric heating system, then fuel is not going to be an issue for you. In your situation, you are far more likely to experience a broken ignitor.

If you want to know more about the potential issues that may cause cold air to blow through the vents, seek out a heating repair professional.
