Why Your Furnace in Red Bluff, CA, Is Blowing Cold Air

Few things are more frustrating during the winter than having a furnace blow cold instead of warm air. A furnace has several intricate parts that work together, and when one or more of these components malfunctions, your home in Red Bluff, CA, can feel unbearably chilly. Read on to learn why your furnace is blowing cold and what you should do about it.

Pilot Light Issues

Checking your furnace’s pilot light should be the first thing you do if your gas system blows cold air. The pilot light ignites your furnace’s burners to ensure your system can generate heat. If this light isn’t on, your burners can’t do their intended job.

Many newer gas furnaces have an electronic ignition switch instead of a pilot light. If this is the case, call a professional to find out why the ignition switch isn’t working.

Malfunctioning Thermostat

A faulty thermostat is another common reason for a furnace to blow cold air. Your thermostat may be signaling the incorrect temperature to your furnace while you think it is set to heat your home.

Ductwork Problems

Issues with your ductwork are another potential reason for your furnace to blow cold air. Leaks or blockages can prevent the hot air from reaching all the rooms in your home. A leak in your ducts can cause the hot air your furnace creates to escape before reaching the intended room while also allowing cold air to enter the ductwork.

Incorrect Furnace Size

The size of your furnace is another factor to consider if your furnace is blowing cold air. If your home’s furnace is too large for the square footage of your home, your system may short cycle and turn on and off too frequently. This can cause your furnace to inadequately heat the air in your home and blow cold air through your vents.
