Why Is My Furnace Blowing Cold Air?

You are inside your home, just about to snuggle up in your bed. Now all you need is that warm air from your furnace. But when you turn it on, you are greeted with cold air instead. Why is that so?

Let us understand some reasons why your furnace emits cold air. 

Reasons Your Furnace Is Blowing Cold Air

Check For Problems With Your Thermostat.

The thermostat is the first thing you should check in case your furnace is not working correctly. Ensure that all the settings are set correctly and that there are no technical issues on your thermostat.

Check On Dirty Filters.

If the furnace filter is dirty or clogged, it will prevent warm air from blowing from the vents. Apart from cleaning the dust and dirt regularly, you must also change your filters every three months. 

Check If The Condensate Is Clogged.

High-efficiency furnaces have what is called a condensate drain. That drain removes water that accumulates over time during the heating process. A clogged condensate drain will stop your furnace from igniting, which means that it will only produce cold air.

There Can Be A Predicament With The Gasoline Equipment. 

Check the pilot light of your furnace. The pilot light needs to be lighted at all times for your furnace to produce warm air. If there is an issue with the gas supply, your furnace’s sensors will detect it and automatically shut off the gas supply to prevent your home from being filled with harmful gas. If your pilot light doesn’t light at all, it may be because of the gas valve. That is not an issue you can solve on your own. 

You can solve trivial problems with the thermostat or filters at home itself. But if the furnace continues to blow cold air even after that, then calling an authorized HVAC company will be the best idea.
