Why Is My Furnace Blowing Cool Air?

cold-manWe are certainly starting to feel cold temperatures hinting that winter is truly right around the corner now, aren’t we? With that in mind, most homeowners have already taken stock of their home heating systems, hopefully getting them tuned up for the season and scheduling repairs for any issues that may have popped up. Unfortunately, there is really no way to guarantee that you won’t run into any problems as the heating season progresses. You may just find that your furnace is not functioning properly at some point.

Now, certain problems with a furnace may manifest themselves with very subtle symptoms. Others, however, are quite obvious. It doesn’t take an HVAC expert to realize that a furnace blowing cool air is not one that is operating the way it should. It does require a professional heating technician to complete any necessary furnace repairs in Plainfield, IL,  though. If you notice that your furnace is blowing out air that is cooler than it should be, contact us to have the problem resolved promptly.

Check Your Thermostat!

The last thing that you want to do is to schedule professional repairs that you don’t need for problems that you don’t have. That is why we kindly remind you to doublecheck your thermostat before you go ahead and schedule your furnace repairs. If your thermostat’s fan is set to “on” then it is going to run even when air is not actively being heated. Switching it to “auto” ensures that the fan is only running when the furnace is actually heating air.

Is the Pilot Out?

If you have a furnace that uses a standing pilot light, then you are going to need for that pilot light to be lit if you want your furnace to heat air. If the pilot light on your furnace is out, relighting that pilot may be all that you need to get your furnace heating air properly again. However, if this pilot light refuses to stay lit, you may have a faulty thermocouple, or you could actually have a problem that is putting your safety at risk and forcing the light out. You need a professional to determine if this is the case.

Are Your Ducts to Blame?

It is actually possible that your furnace is operating just fine, despite the fact that you notice cool air blowing from it. The problem could lie with your ductwork. Is the cool air coming from just one vent, or being introduced to just one area of the house? If so, then you very well could have a leak in your air ducts servicing that area. By having your ducts tested and effectively sealed, you can resolve the problem so that you are not paying more for less comfort, while also putting added strain on your heating system.
