DIY furnace fixes

Try these easy fixes before calling a pro.


If your furnace is blowing cool air...

  • Check the thermostat switch. Check to make sure it's set to "HEAT" and not "COOL". (As obvious as this might sound, it happens.)

  • Change your air filter. A dirty filter restricts air flow and can cause a lot of furnace issues. If yours is dirty, replace it with a new one.

  • Relight your pilot light. If you have an older gas furnace, it likely uses a permanently lit pilot light to heat your home. If the light goes out, simply relight it. If it keeps going out, you have a bigger issue.

  • Make sure the gas is on. If your furnace isn't getting any gas, it can't heat your home. Make sure the gas valve lever is in the "ON" position (that is, parallel to the gas supply pipe).


If your furnace isn't blowing air at all...

  • Change the thermostat batteries. If the thermostat batteries are dead, your furnace won't even turn on.

  • Make sure your vents are open and clear. Check to make sure a supply vent (the ones that push out warm air) didn't accidentally get closed. Also, make sure your return vents (the ones that pull in cold air from your home) aren't blocked by anything.

  • Check your circuit breaker. Make sure your breaker isn't tripped. If it is, just push it back to the "ON" position. If it keeps tripping, don't keep resetting it. This means you have a bigger problem.

Is your furnace still isn't working? It's time to call a professional.

If your unit is more than 10 years old, it could be on it's way out, which means it might be time to replace your furnace.
