What Homeowners Must Know During Winter Storms and Heavy Snowfall
Winter storms in New England bring more than inconvenience — they can create serious safety risks when snow and ice block exterior vents around a home. Many homeowners don’t realize that furnace vents, boiler exhausts, dryer vents, and intake pipes must remain clear at all times, especially during heavy snowfall.
At HKF Construction, we frequently respond to winter-related emergencies caused by blocked vents. Understanding what each vent does and why snow removal is critical can help prevent equipment failure, carbon monoxide risks, and costly repairs.
We proudly serve Medford, Somerville, Cambridge, Arlington, Belmont, Watertown, and Greater Boston.
Why Snow Around Vents Is Dangerous
When snow piles up around exterior vents, it can:
- Block exhaust gases
- Restrict fresh air intake
- Cause heating systems to shut down
- Trigger carbon monoxide buildup
- Damage mechanical equipment
- Create emergency situations during storms
These issues often happen silently and escalate quickly.
Common Exterior Vents You Must Keep Clear
Furnace and Boiler Exhaust Vents
These vents expel combustion gases from gas or oil heating systems. If blocked by snow:
- Exhaust gases can back up into the home
- Carbon monoxide levels can rise
- The system may shut down for safety
These vents are usually PVC or metal pipes exiting the side of the house.
Combustion Air Intake Vents
Many modern systems use a separate intake vent to bring fresh air into the unit. If intake vents are buried:
- The system cannot operate properly
- Efficiency drops
- Equipment may shut off
Both intake and exhaust vents must remain fully exposed.
Dryer Vents
Snow-blocked dryer vents can:
- Trap moisture inside the duct
- Reduce dryer efficiency
- Increase fire risk
- Cause lint buildup
These vents are often overlooked during storms.
Bathroom and Kitchen Exhaust Vents
Blocked exhaust vents can lead to:
- Moisture buildup
- Mold risk
- Reduced ventilation
- Ice formation inside ducts
Snowstorms and Emergency Situations in New England
During heavy snow or nor’easters:
- Snow can drift several feet high
- Ice can seal vents overnight
- Melting snow can refreeze around openings
Homeowners should check vents multiple times during extended storms, especially after plowing or snow removal.
Best Practices for Winter Vent Safety
- Clear snow at least 12–24 inches around each vent
- Avoid piling snow near sidewall exhausts
- Never cover vents intentionally
- Check vents after every major snowfall
- Install carbon monoxide detectors on every level of the home
