(937) 269-5059When the brutal winter weather of the Midwest hits, the last thing you want is for your furnace to quit working correctly. Furnace problems can be frustrating, but they don’t always have to result in a cold wait for a technician and a large bill at the end. There are some minor issues that you can inspect yourself, so don’t panic. According to Allied Services, Inc., there are five common reasons your furnace could be blowing cold air.
1. Has Your Furnace Warmed Up?
If you get a blast of cold air when you first turn on your furnace and then the air turns warm, it just means that the furnace needed a few minutes to warm up. The furnace must push the cold air out of the vents before the warm air can come through.
2. What Is Your Thermostat Setting?
If your thermostat is set to “on” instead of “auto”, the fan will blow air continuously. You can switch the thermostat to “auto” to remedy this issue.
3. Is the Flame Sensor Clean?
A flame sensor is used in pilotless furnaces to keep the furnace burning once it starts. If the flame sensor gets dirty, your furnace will turn on and begin heating but then turn cold quickly. Cleaning the sensor is pretty simple if you are familiar with furnace parts. But, you can always call a technician to do this if you aren’t completely comfortable doing it yourself.
4. Is the Pilot Light Out?
If you check your furnace and the pilot light is out, you can easily relight it by following the manufacturer’s instructions. If it won’t stay lit, you should call a technician to fix the problem.
5. Is It Time to Replace Your Air Filter?
A clogged air filter will restrict airflow through your furnace, causing it to eventually blow out cold air. Replacing your air filter regularly is a simple way to keep your furnace running efficiently all winter long.
If you have checked these five items and your furnace still is not working properly, call a professional for an inspection. The heating and cooling experts at Allied Services can diagnose and fix your problem, so that you can get warm again quickly. Contact us today at (937) 269-5059 to schedule an appointment.
