1 Why Is My Furnace Blowing Cold Air?

A malfunctioning furnace can be very frustrating.

If the heater isn’t working correctly, the home won’t be comfortable on cold, winter days. Fortunately, there are a few signs that can tell you that something is wrong with your heater. When furnace troubleshooting, one of the most straightforward signs to recognize is when the furnace is blowing cold air rather than hot air. In this article, you will learn a few of the reasons why this can happen.

Malfunctioning Pilot Light Or Flame Sensor

If you have an older furnace, it probably uses a pilot ignite system. If the pilot light is malfunctioning, the heating system will blow cold air rather than hot air. The first thing that you should check is the pilot light. If it is out, you have found the source of the problem. If it is lit, but it continually goes out, you will need to have an HVAC tech inspect the heating system. They will also clean out the system and make any necessary repairs.

If you have a newer heating system, it probably has an electric ignition system. These systems use a flame sensor to blow hot air. If the flame sensor is defective or dirty, your furnace will blow cold air. If this is the case, you will need to have the problem repaired by an experienced furnace repair near my location that has a good reputation.

Ductwork

When the ducts in your home are old, worn out, or damaged…

conditioned air will escape the ductwork. This situation can prevent the hot air from getting to the desired areas of the home. This problem is not uncommon. According to the Department of Energy, the average home loses between 20 to 30 percent of its conditioned air as a result of leaky ducts.

If your ductwork is old, you should hire an HVAC company to come to your home to inspect it. Ducts are usually behind the floors, ceilings, and the walls. The duct’s location can make it difficult for you to check them yourself. Hiring a professional to inspect and replace the worn or damaged ducts can save you money on your monthly heating costs.

Clogged High-Efficiency Vent Pipes

In most cases, the placement of the vents pipes in high-efficiency furnaces are outdoors. Due to the location, the pipes can easily accumulate debris such as ice and snow. Over time, this can cause a clog. If the pipes are clogged, the heater will blow cold air, or it will shut down completely.

Thermostat Setting

Your thermostat setting has a lot to do with…

the temperature of the air that comes from the heater. The thermostat fan has a few settings. If your thermostat’s setting is “ON,” it is possible that it will blow cold air. The blower will constantly run, even if the furnace is not working. There is an easy fix for this problem. If you set the thermostat’s fan to “AUTO,” the blower will only operate when the heating system is turned on. When changing the setting, you should also check to make sure that the batteries in the thermostat are not dead.

Overheating

Furnaces have a safety feature called the limit switch. If your furnace overheats, it will automatically turn off the burners. This safety feature allows the heater to cool down to a safe temperature. When the heating system shuts down, it will blow cold air. One primary reason that the furnace overheats is because the air filter is dirty. A dirty air filter will also make the system work much harder than it needs to. For this reason, it is so important to replace your air filter regularly. Regularly replacing the air filter will keep the home warm, save you money, and prolong the life of the furnace.
