❄️Snowstorm Warning: High-Efficiency furnaces ❄️

With the potential of heavy snow, please remember to check your high-efficiency furnace vent pipes (usually white PVC pipes on the side of your house).
Snow can drift and block these pipes, causing your furnace to shut down (a safety feature!) or, in severe cases, trigger a carbon monoxide alarm.

➡️Action Item: Take 2 minutes to clear snow away from the vent termination.

➡️Stay Safe: Ensure your CO detectors are working!

Stay warm, everyone!
We will be able for no heat calls
