Winter Home Maintenance Checklist

Winter maintenance focuses on keeping your home warm, preventing costly damage from freezing temperatures, and ensuring your family's safety during harsh weather. This checklist will help you stay on top of critical winter tasks throughout the coldest months.

HVAC System Maintenance

Heating System

Monthly tasks:

• Replace or clean air filters (critical for efficiency and air quality)
• Check that heat is flowing from all vents
• Monitor your energy bills for unusual spikes
• Listen for unusual noises from the furnace or heat pump
• Test your thermostat regularly

Regular inspection:

• Check area around furnace for proper ventilation
• Ensure vents and registers are open and unobstructed
• Look for signs of soot or unusual odors
• Monitor carbon monoxide detectors (test monthly)
• Check that the system is maintaining set temperature

When to call a professional:

• Heating system isn't working or isn't heating effectively
• Unusual noises, odors, or frequent cycling

Ductwork

Check for issues:

• Inspect visible ductwork for leaks or damage
• Ensure all vents are open and clear
• Check insulation on ductwork in unconditioned spaces
• Feel for cold air coming from vents (may indicate a problem)

Thermostat Management

Optimize heating:

• Set thermostat to 68°F when home, lower when away or sleeping
• Use a programmable or smart thermostat for automatic adjustments
• Avoid setting the thermostat too high (it won't heat faster, just waste energy)
• Consider zone heating if you have a large home

Preventing Frozen Pipes

Outdoor Faucets

Protect exterior plumbing:

• Ensure all outdoor faucets are turned off and drained
• Disconnect and store garden hoses
• Install frost-free faucet covers
• Check that faucets aren't dripping (indicates they may not be fully closed)

Indoor Plumbing

Protect vulnerable pipes:

• Insulate pipes in unheated areas (attics, crawl spaces, garages, basements)
• Keep cabinet doors open under sinks to allow warm air to circulate
• Let faucets drip slightly during extreme cold (moving water freezes less easily)
• Know where your main water shutoff valve is located
• Keep garage doors closed if water lines run through the garage

During Extreme Cold

Emergency precautions:

• Open cabinet doors to allow warm air to reach pipes
• Let cold water drip from faucets served by exposed pipes
• Keep thermostat set to at least 55°F even when away
• If you're going to be away, consider shutting off water and draining the system
• Never turn off heat completely, even in vacant homes

If Pipes Freeze

What to do:

• Turn off water supply at the main valve immediately
• Open affected faucets
• Slowly thaw pipes with a hair dryer, heat lamp, or warm towels (never use open flame)
• Start thawing at the faucet end and work back toward the frozen area
• If pipes have burst, call a plumber immediately
• Document damage for insurance purposes

Energy Efficiency

Windows and Doors

Reduce heat loss:

• Check weatherstripping for gaps or damage
• Use draft stoppers at the bottom of doors
• Close curtains and blinds at night to retain heat
• Consider window insulation film for older, drafty windows
• Ensure doors seal properly when closed

Insulation and Sealing

Keep warm air in:

• Check attic insulation levels (heat rises, so attic is critical)
• Seal air leaks around windows, doors, and electrical outlets
• Inspect and repair ductwork insulation
• Check insulation around pipes in unconditioned spaces
• Ensure attic access door is properly insulated

Fireplace

If you have a fireplace:

• Keep damper closed when not in use (prevents heat loss)
• Consider installing glass doors to reduce heat loss
• Have chimney cleaned and inspected annually
• Use fireplace only for occasional use (they're not efficient primary heat sources)

Exterior Maintenance

Roof and Gutters

Monitor for winter damage:

• Check for ice dams (ridges of ice that form at roof edges)
• Remove snow from roof if accumulation is excessive (use a roof rake, be safe)
• Ensure gutters are clear (ice and snow can cause damage)
• Look for signs of leaks or water damage in attic
• Trim tree branches that could fall on roof during storms

Ice Dams

Prevent and address:

• Ensure proper attic insulation and ventilation
• Remove snow from roof edges with a roof rake (be extremely careful)
