Most homeowners in Tuckerton, NJ expect their furnace to blow hot air when they turn it on. However, that’s not always the case as furnaces may blow cool air if there’s a problem. Here are some reasons why your furnace may be blowing cool air.
1. Ignition Problem
If your furnace uses a standing pilot light or electronic ignition, it may be the case that the ignition system is not working properly. In this instance, you’ll need to contact a professional to look at your furnace and fix the problem.
2. Dirty Filter
A dirty filter can also cause your furnace to blow cool air and affect the whole heating system. The filter clogs with dirt and debris can restrict airflow and cause your furnace to overheat. As a result, your furnace will shut down and blow cool air instead of hot.
3. Thermostat Issues
Your thermostat may also be the reason your furnace is blowing cool air. If the thermostat is not set to the “heat” mode or the temperature is too low, your furnace will blow cool air. In addition, a faulty thermostat can also cause your furnace to blow cool air.
4. Blocked Vents
Furniture or other objects can block your vents, restrict airflow, and cause your furnace to overheat. Your furnace will shut down and start blowing cool air. To fix this problem, remove any obstructions and ensure that all of your vents are clear.
5. Pilot Light Issues
If your furnace has a pilot light, it may be that the pilot light is not lit. If this is the case, your furnace will not be able to generate heat and will start blowing cool air. You will need to relight the pilot light according to the instructions in your owner’s manual.
