It’s a cold winter morning, and you turn on your furnace to find nothing but cold air coming out. That’s no way to start the day. Instead of panicking, here’s a quick guide to help you figure out why your furnace is blowing cold air.
A Clogged Air Filter
When your air filter is dirty and clogged, it can lead to overheating of the heat exchanger. When this happens, the high limit switch can trip and turn off the burners that heat the air that comes from your furnace. A clean air filter is essential for proper furnace function.
The Thermostat is Set to Fan
If your thermostat setting is on “fan,” that means the fan will run whether the furnace is blowing heat or not. The fan on constantly will cause cold air to come through the vents when the furnace isn’t on. Set it to “auto,” and it should fix the problem.
The Pilot Light Has Gone Out
The pilot light ignites the flame that turns on the furnace burners to heat the air that warms your home. If the pilot light goes out, the burners can’t turn on, and the furnace can’t heat the air. Relighting the pilot light should fix the problem.

Cold winter weather means there’s a risk for frozen pipes in your plumbing system. Let’s look at what happens when your pipes freeze and how to prevent it.
When Pipes Freeze
Water expands when it freezes, leading to increased pressure in your pipes which can cause them to burst. Because of this, any water in your pipes exposed to extreme cold is at risk of getting cold enough to do damage.
Signs of Frozen Pipes
There are some distinct signs that you could have frozen pipes. They include:
- No water coming out of the faucets
- Frost on the outside of your pipes
- An unusual smell coming from your drains
- Gurgling or clanging coming from your pipes
What to Do If Your Pipes Freeze
If you think you might have frozen pipes, it’s critical to act quickly. Frozen pipes can rupture and lead to extensive water damage in your home. Make sure you contact a professional plumber before trying to thaw or repair the pipes yourself.
Preventing Frozen Pipes
Some steps to prevention might seem like a pain, but they’re much easier than dealing with frozen pipes. A few measures to take to keep your pipes from bursting include:
- Drain your irrigation lines before winter
- Insulate areas where plumbing is close to exterior walls
- Detach outside hoses from spigots
- Talk to a plumber about how to protect the pipes in your home
