5 Possible Reasons Why Your Furnace Is Blowing Cold Air

Hardwood floors are perfect until winter. No one likes waking up in the morning and walking on a freezing cold floor. However, some may just have to do so if their furnace is blowing cold air! I can’t even imagine that agony. What’s the point of having a furnace if it doesn’t produce heat! Here are a few things to check before calling in the pros.

1. Check Your Thermostat.

If your thermostat is more than a few years old, it’s probably time for a new one. There are smart thermostats that will automatically raise and lower the temperature according to how you program it. This can be extremely helpful come bill time. Make sure the thermostat setting is switched to auto instead of on. The on switch will make your system blow cold air all day every day. Also, it’s not ideal for lower monthly bills. (I learned the hard way)

2. Possible Over Heating Furnace

Sometimes a furnace will overheat and the safety device turns off the burners. The most common reason for an overheated furnace is a dirty air filter. It is hard to imagine that a solution as simple as replacing the air filter will solve the problem. However, that is sometimes all it takes!

3. Pilot Light Issues

The first step is to try to light the pilot light again. Check the area around the pilot light to ensure it is clean and not stopped up with dirt or debris. The thermocouple may be the problem if your pilot light will not stay lit. If this is the issue, you should call a qualified technician for service. The flame sensor could also be the problem. It may need to be cleaned or replaced in order for your heating system to start working again.

4. Check the Breaker Panel

Believe it or not, a lot of the times a breaker just may need to be switched. Be sure to check that before calling to save yourself some money and time!

5. Check Oil Tank (If necessary)

If your heating system uses oil, then you should check to ensure the oil tank is not out of fuel.

If none of these seem to be the issues, we recommend calling in the professionals to help solve this issue.
