During winter storms, snow and ice can create hidden dangers around your home, especially when it comes to dryer vent exhausts and the PVC intake and exhaust pipes connected to your HVAC system and water heater. At Advanced Air Duct Cleaning, we want to help homeowners stay safe, warm, and energy‑efficient all winter long.
Why Snow Build‑Up Is a Serious Concern
Many modern dryers, high‑efficiency furnaces, boilers, and water heaters vent to the outside through low‑level exhaust pipes. When snow accumulates or drifts against these vents, it can cause serious problems including:
- Carbon monoxide buildup inside the home
- Dryer overheating and fire risk
- System shutdowns or equipment damage
- Reduced efficiency and higher energy bills
- Moisture and ice damage to vents and siding
Blocked Dryer Vent Exhausts
Your dryer vent releases hot, moist air to the outside. If snow or ice blocks this exhaust:
- Lint and heat can back up inside the dryer
- Clothes may take much longer to dry
- The dryer can overheat, increasing fire risk
- Moisture may be forced back into the home
What to do:
- Regularly check the exterior dryer vent during and after snowstorms
- Keep at least 12–18 inches of clearance around the vent
- Remove snow, ice, and debris carefully—do not use sharp tools
- Make sure the vent flap opens freely
Blocked HVAC & Water Heater PVC Pipes
High‑efficiency furnaces and water heaters use PVC pipes for air intake and exhaust. These pipes are often located close to the ground and are especially vulnerable to snow blockage.
If these pipes are blocked:
- Carbon monoxide may not vent properly
- Safety sensors can shut the system down
- The system may repeatedly fail to start
- Dangerous gases could leak into living spaces
Warning signs include:
- Furnace or water heater turning off unexpectedly
- Error codes on the system
- Unusual smells or poor indoor air quality
- Carbon monoxide detector alarms
Winter Safety Tips for Homeowners
- After every snowfall, inspect all exterior vents and pipes
- Clear snow away immediately, especially after plowing or drifting
- Keep pathways open to vents so they are easy to access
- Never cover vents to “protect” them from snow
- Ensure carbon monoxide detectors are installed and working properly

If your system shuts down, your dryer isn’t venting properly, or you’re unsure whether a vent is blocked, do not ignore it. Blocked exhaust systems can be dangerous.
