As homeowners in Rochester, NY know all too well, winter storms can dump a lot of snow in a short period of time. While most people remember to shovel their driveways and walkways, one often-overlooked danger hides in plain sight — blocked HVAC intake and exhaust vents.
At Home Watch USA, a trusted provider of home watch services in Rochester, we routinely discover this issue during our winter inspections of vacant and seasonal homes. It’s a simple problem, but one that can have very serious consequences if left unaddressed.
Why Blocked HVAC Vents Are a Serious Winter Risk
Many high-efficiency furnaces and water heaters vent through the side of the home instead of the roof. These air intake and exhaust pipes are typically low to the ground, which means they’re vulnerable to:
-
Heavy lake-effect snowfall
-
Snowdrifts caused by wind
-
Accumulated ice or sleet
-
Snow piled by shoveling or plowing
When these vents become blocked, the consequences can be severe:
1. Carbon Monoxide Backup
A blocked furnace exhaust pipe can cause carbon monoxide (CO) to back up into the home. This colorless, odorless gas is deadly and often undetected until symptoms set in or alarms go off. This is a critical concern for vacant or seasonal homes, where no one may be present to respond.
2. HVAC System Failure
Modern HVAC systems include safety shutoffs to prevent carbon monoxide poisoning. If the vent is blocked, your heating system may shut down completely, which can leave your home vulnerable to frozen pipes, burst plumbing, and water damage — especially during Rochester’s freezing temperatures.
3. Reduced Energy Efficiency
Even partial blockages can cause your HVAC system to work harder, leading to higher energy bills and long-term damage to your equipment.

How to Prevent HVAC Vent Blockages
If you live in your home year-round or visit frequently, here are a few winter maintenance tips to protect your property:
-
After each snowstorm, check your HVAC intake and exhaust pipes and clear away any snow or ice.
-
Keep a clear radius of at least 3 feet around vent openings.
-
Consider installing protective covers or hoods (check with a licensed HVAC technician for safety).
-
Test all carbon monoxide detectors monthly and replace batteries twice a year.
