Why Is My Heater Blowing Cold Air?

The last thing you expect when your furnace comes on is for the system to blow cold air throughout your house. That air is supposed to warm up the space, but just the opposite will happen when something isn’t working correctly. There are various causes for this problem, and the following article will touch on some of those issues.

Start with These Solutions

Although you are sure to be frustrated when your furnace isn’t producing the warm air you expect, it’s possible that there will actually be a rather simple solution to the problem. Before you get ahead of yourself and start thinking that the whole system will need to be replaced, explore the potential that one of the issues below is to blame.


  • Out of fuel. In some cases, cold air coming from your heater could simply indicate that you are out of fuel and need to have your tank refilled. In this case, the heater will have nothing to burn, and no way to generate heat. Call to place an order to have your propane or heating oil tank refilled right away and you should be back in business shortly.


  • Tech trouble. Since your heating system is likely controlled by a simple computer circuit in the thermostat, it may be that you simply need to reset the system to get it back on track. Follow the instructions provided with your thermostat to turn it off and back on, and you could have solved the problem just that easily.


  • Pilot light went out. Without a pilot light, your furnace won’t be able to ignite, and no warm air will be produced. If you know how to check the pilot light for your system, do so to make sure this isn’t the underlying cause of the cold air.


Other Possibilities to Consider

In a best-case scenario, one of the points listed above will solve your problem, and you can move on. If not, you may need to call for heater service to have a professional review the situation and figure out what is going wrong. While you likely won’t be able to fix any of these troubles on your own, it can be helpful to understand some of the possibilities, such as those below –


  • Duct problems. It could be that the warm air is actually being created by the furnace, but it is being lost before it reaches the vents. This would indicate a problem somewhere in the ductwork, and your home will only be warm again once those ducts are fixed.


  • Overheating issues. Your heater will shut itself down if it overheats, and that can happen when not enough air is moving through the system. You could potentially solve this with a new air filter, but it might take a professional to get to the heart of the problem.


  • Dirty equipment. Over the years, your heater’s components are going to collect dirt, and various parts might start to fail as a result. A professional cleaning, and perhaps the replacement of some parts, may be in order.
