You rely on your furnace to keep you warm during the long, cold Dayton winters. But if your heating system is blowing cold air, then there are three common reasons such as thermostat problems, overheated furnace or the pilot light is out.
It could also be caused by your breaker switch being switched off. The first step in determining whether you need to call a technician is to check the electrical box to ensure all switches are in the on position. A breaker that is tripped will be in the off position.
1. Thermostat Issues
If your thermostat is more than a few years old, you should consider replacing it. There are smart thermostats that will automatically raise and lower the temperature according to how you program it. This can save you a lot of money on your monthly energy bills.
Make sure the thermostat setting is switched to auto instead of on. The on switch will make your system blow cold air, and the room temperature will not be comfortable in the winter.
2. Overheated 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.
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 to get your heating system working again.
If the above issues have been checked, and the system is still blowing cold air, then you will likely need to have one of our clean, screened, trained, and timely techs check the igniter or circuit board.
If your heating system uses oil, then you should check to ensure the oil tank is not out of fuel. Warm air may also leak through faulty duct work. The best way to ensure that your heating system is in good condition is to schedule a CJS Furnace Safety Check and Tune-Up.
