Furnace Blowing Cold Air?

In the winter the last thing you want is to blow cold air when it is bitter cold outside. This is a dilemma that needs to be resolved as soon as possible. There are a few common explanations for this type of occurrence. A trained professional can pinpoint the exact cause of this issue. Below are some possible reasons for this occurrence.

The Furnace May Be Overheated

Your unit may start off blowing hot air, it turns cold, and suddenly no air is blowing out. This scenario may be an indication of an overheated furnace. A safety switch on the unit can turn the burners off. This is known as a limit switch. Once this switch is turned, it continues blowing to bring the unit to a safer level. One common reason for overheating is an old and dirty filter. If your unit appears to be overheating, never ignore it. Continued overheating will cause many preventable problems. Ignoring this problem will only lead to more costly problems.

Check The Pilot Light

Another cause for cold air blowing out from your unit might be the pilot light. The light might have gone out. The flame may have gone out. You may need to relight the pilot light. Not everyone is comfortable relighting pilot lights as it can sometimes be difficult. A trained technician can check the unit and relight the flame or find a solution.

A Problem With The Thermostat

Cold air blowing from your unit may result from a problem with the thermostat. It may need to be replaced, or the setting may have issues connecting to the unit. If the unit is constantly running, or intermittently blowing cold air, it is time to call a professional for the job.

There may be a combination of issues causing your unit to blow cool air. Multiple issues can be solved with thought and some troubleshooting. The thermostat may need replacing, or the settings might need to be adjusted. The multiple issues may involve a dirty filter and issues with the thermostat. If you notice your unit is blowing cold air instead of warm air, do not panic. Remember a little troubleshooting will lead to sound solutions. It is not uncommon to experience multiple issues when cold air is blowing from your unit. For more information about how to care for your furnace, please contact us the team at Romano Brothers.
