Essential Winter HVAC Preparation Checklist
🍂 October: Early Preparation (4-6 weeks before cold weather)
1. Schedule Professional Maintenance
What's Included in Professional Service:
- • Complete system safety inspection
- • Heat exchanger and flue examination
- • Burner cleaning and adjustment
- • Thermostat calibration
- • Electrical connection tightening
- • Gas pressure and leak testing
- • Efficiency testing and optimization
- • Filter replacement
- • Ductwork inspection

💡 Pro Tip: Schedule early October for best availability and pricing. Many companies offer fall tune-up specials.
2. Test Your Heating System
Complete System Test Procedure:
- 1. Set thermostat to heat mode, temperature 5°F above current
- 2. Listen for system startup (should begin within 1-2 minutes)
- 3. Check all vents for warm air within 5-10 minutes
- 4. Verify even heating throughout the home
- 5. Note any unusual sounds, smells, or performance issues
- 6. Test emergency shut-off switches and procedures
⚠️ Call immediately if you notice: Gas odors, strange sounds, no heat after 15 minutes, or yellow/orange flame color (should be blue).
3. Inspect and Replace Air Filters
Filter Inspection Steps:
- • Remove filter and inspect for dirt/damage
- • Hold up to light - should see through clean filter
- • Check filter size and MERV rating
- • Note installation direction arrows
- • Stock up on winter supply (3-4 filters)
Winter Filter Schedule:
- • October: Install fresh filter
- • December: Check and likely replace
- • February: Mid-winter replacement
- • March: End-of-season inspection
❄️ November: Final Preparations (2-3 weeks before cold weather)
4. Seal Air Leaks and Improve Insulation
Priority Sealing Areas:
- • Windows and doors (weatherstripping)
- • Electrical outlets on exterior walls
- • Baseboards and crown molding gaps
- • Attic access hatches
- • Basement and crawlspace access
- • Ductwork connections and joints

- • Chimney and flue connections
- • Garage door seals
- • Window AC unit removals
💰 Savings: Proper air sealing can reduce heating costs by 10-20% and significantly improve comfort.
5. Clean and Inspect Vents and Ductwork
Comprehensive Vent Maintenance:
- 1. Remove all vent covers and wash with soap and water
- 2. Vacuum inside ducts as far as you can reach
- 3. Check for obstructions (furniture, curtains, rugs)
- 4. Inspect for damage, rust, or loose connections
- 5. Ensure all vents open and close properly
- 6. Balance airflow by adjusting dampers if needed
⚠️ Professional duct cleaning may be needed if you notice excessive dust, mold, or haven't cleaned ducts in 3-5 years.
6. Outdoor Unit Preparation
For Heat Pumps:
- • Clear debris from around unit (3-foot clearance)
- • Trim vegetation and remove leaves
- • Clean coils if visibly dirty
- • Check refrigerant lines for damage
- • Ensure unit is level and secure
- • DO NOT cover completely!
For AC-Only Units:
- • Turn off power at disconnect
- • Cover with breathable cover
- • Secure cover against wind
- • Check for pest intrusion
- • Drain any standing water
- • Remove window AC units if possible
🏠 Ongoing Winter Maintenance (December - March)
7. Monthly Filter Checks and Replacement
Winter Filter Schedule:
Check Monthly:
- • Visual inspection for dirt buildup
- • Airflow test at vents
- • System runtime monitoring
- • Energy bill comparison
Replace When:
- • Filter looks dirty or clogged
- • Airflow seems reduced
- • System runs longer cycles
- • Every 30-90 days maximum
8. Snow and Ice Management
Winter Weather Protection:
Heat Pump Care:
- • Gently remove snow from top and sides
- • Keep coils clear of ice buildup
- • Don't use sharp tools that could damage coils
- • Ensure drainage isn't blocked by ice
- • Check for excessive frosting
Exhaust Vents:
- • Keep furnace exhaust vents clear
- • Remove snow from intake vents
- • Check for ice dams blocking vents
- • Ensure carbon monoxide can exit safely
- • Maintain 3-foot clearance around vents
9. Monitor System Performance
Weekly Monitoring Checklist:
Performance Indicators:
- • Consistent temperatures in all rooms
- • Normal startup and shutdown cycles
- • Quiet operation without unusual sounds
- • Steady energy usage patterns
Warning Signs:
- • Frequent cycling on and off
- • Uneven heating between rooms
- • Unusual sounds or odors
- • Sudden energy bill increases
🌡️ Temperature Tip: Set your thermostat to 68-70°F when home and 65-68°F when away. Every degree lower saves 6-8% on heating costs.
