Navigating through the up and down temperatures of this winter can be difficult, but if it recently snowed and you find your furnace not working, we may know why.
While it is entirely possible that this could be a larger issue, especially if you have an older furnace, there is one thing you should definitely check before you call a service technician: Ensure your intake and exhaust pipes are clear of snow!
Some furnaces – especially new, high-efficiency furnaces – have exhaust or intake pipes that run to the exterior of the house. When there are large snowfalls or snowfalls with high winds, snow can clog up these pipes. As a result, your furnace will hit the emergency stop button. Some furnaces recognize that more costly issues can develop without proper venting. So in essence, the shutdown function is intended to prevent this from happening.
So, before you cost yourself a service call, here is a walk-through of the troubleshooting process:
- Find where the exhaust/intake pipes are connected to your furnace. These pipes will be non-metallic (likely plastic), they will attach to your furnace and end on an exterior wall. Once found, follow them outside and get your snow gear ready!
- Once you’re all bundled up and have your shovels ready, find where you think the pipes lead to and start digging. You’ll want to clear all snow from around the area to ensure you don’t have a continuing issue. Once done, check and see if there is anything clogging the pipe(s).
- When you’re done clearing the snow, your furnace should begin running on its own. If it doesn’t begin running immediately, you may need to start it yourself (using the starting instructions attached to your furnace).
Note: This info can also apply to the fall months with leaves, and plastic bags that can get sucked into the venting.
