Reasons Why Your Furnace Is Blowing Cold Air

As the weather begins to shift from warm to cool here in the Keystone area, homeowners are beginning to switch over from using air conditioning to using heating. With this time of year – you may find yourself needing to use both on some days. But for many homeowners, it will be the first time they’ve turned on their furnace since last winter or spring. Sometimes, when you turn your system back on, it may not operate properly.

In our last post, we discussed the importance of routine furnace maintenance. However, in this article we are going to show you several reasons why your furnace may be blowing cold air instead of that cozy warm air that you expect.

5 Reasons Why Your Furnace Isn’t Working Correctly

1. Incorrect thermostat settings: during times of the year where your thermostat is frequently being switched up and down, it can mess with some of the settings needed to ensure proper operation. Check your thermostat fan setting and make sure that it is set to AUTO instead of ON. When the thermostat is set to ON, it means that the fan will constantly run without providing heat. It is important to not have the fan set to ON, because it can cause costly furnace repair.
2. Your furnace is overheated: if you have not recently changed your air filter, the burner in your furnace may have shut down. The reason this is caused is because the old clogged air filter compromises the air flow, causing the furnace to overheat. Be sure to change your air filter routinely.
3. Pilot light has gone out: If you have an older gas furnace that requires a continuous pilot light, it may have gone out. There are many reasons why this could happen. Most often, it’s because of a gust of air that blew it out. You can relight the pilot light yourself if you feel comfortable with it.
4. Leaking ductwork: this is a very common cause of discomfort in your home. If you have ripped or leaky ducts in your attic or crawl space, you may be experiencing cool or cold air in the home when you are running your furnace. Additionally, this can cause high energy bills. If you suspect ripped ducts, contact a professional for professional ductwork repair.
5. Faulty electronic ignition: if you have an electric furnace, which is more common in newer homes, you may have a faulty electronic ignition – which causes the furnace to not operate correctly. This problem is more difficult to solve than the pilot light, and require a professional HVAC repair technician.
