Energy Efficiency Tips: Lowering Your HVAC Bills in Wisconsin

The Wisconsin Energy Challenge

Wisconsin homeowners face some of the highest heating costs in the nation. With winter temperatures regularly dropping below zero and summers increasingly hot and humid, your HVAC system works hard year-round. The average Wisconsin household spends over $2,000 annually on heating and cooling. These energy efficiency strategies can reduce that burden significantly.

Heating Efficiency Strategies

Optimize Your Thermostat

Smart thermostat use saves money without sacrificing comfort:

• Set it and forget it: 68 degrees while home, 60-62 degrees while sleeping or away
• Each degree matters: Lowering temperature 1 degree saves approximately 3% on heating costs
• Avoid constant adjustments: Let the system maintain steady temperatures
• Consider a smart thermostat: Learns your patterns and adjusts automatically, saves 10-15% on average

Seal Air Leaks

Air infiltration wastes enormous energy. Common leak locations:

• Around windows and doors
• Electrical outlets and switches on exterior walls
• Where plumbing and wiring penetrate walls
• Attic access hatches
• Recessed lighting fixtures
• Fireplace dampers

Sealing these leaks with caulk, weatherstripping, and spray foam can reduce heating costs by 10-20%.

Insulation Matters

Proper insulation keeps heat where you want it:

• Attic: R-49 minimum recommended for Wisconsin (many older homes have far less)
• Walls: R-13 to R-21 depending on wall type
• Basement/crawlspace: Insulate rim joists and walls

Adding attic insulation often pays for itself within 2-3 years through energy savings.

Furnace Maintenance

A well-maintained furnace runs more efficiently:

• Replace filters monthly: Dirty filters make the system work harder
• Annual tune-up: Professional maintenance improves efficiency 5-15%
• Keep vents clear: Do not block registers with furniture or rugs
• Seal ductwork: Leaky ducts lose 20-30% of heated air

Cooling Efficiency Strategies

Use Your AC Wisely

Air conditioning costs add up quickly:

• Set thermostat higher: 78 degrees when home, higher when away
• Use fans: Ceiling fans allow you to raise AC setting 4 degrees with no comfort loss
• Close blinds: Block direct sun, especially on south and west windows
• Avoid heat generation: Use grill instead of oven, dry clothes at night

Reduce Cooling Load

Less heat entering your home means less cooling needed:

• Window treatments: Reflective or insulating window films and shades
• Landscaping: Shade trees on south and west sides reduce cooling loads significantly
• Roof color: Light-colored or reflective roofing stays cooler
• Attic ventilation: Proper ventilation prevents heat buildup

AC Maintenance

Keep your cooling system efficient:

• Clean or replace filters monthly: Essential for efficiency and air quality
• Clear debris: Keep outdoor unit free of leaves, grass, and obstructions
• Annual service: Professional tune-up before cooling season
• Check refrigerant: Low levels reduce efficiency dramatically

Year-Round Efficiency Habits

Manage Humidity

Humidity affects perceived temperature:

• Winter: 30-40% humidity feels warmer, allowing lower thermostat settings
• Summer: Dehumidification makes higher temperatures comfortable

Use Exhaust Fans Wisely

• Run bathroom fans during and briefly after showers
• Use kitchen exhaust when cooking
• Do not leave fans running—they push conditioned air outside

Take Advantage of Natural Conditions

• Open windows when outdoor temperatures are pleasant
• Use window fans to bring in cool night air in summer
• Let sunlight warm south-facing rooms in winter

Upgrade Considerations

Sometimes efficiency requires investment:

High-Efficiency HVAC Equipment

• Furnace: 95%+ AFUE models save 15-25% versus older units
• Air conditioner: 16+ SEER models significantly more efficient than minimum
• Heat pump: Modern cold-climate models work efficiently even below zero

Smart Thermostats

Investment: $150-300. Typical savings: $150+ annually. Features:

• Learning capabilities
• Remote control via smartphone
• Energy usage reports
• Integration with other smart home devices

Duct Sealing and Insulation

Leaky, uninsulated ducts waste 20-30% of heating and cooling. Professional sealing typically costs $1,000-2,000 and pays back within 2-3 years.

Wisconsin Energy Incentives

Take advantage of available programs:

Focus on Energy

Wisconsin's statewide energy efficiency program offers:

• Rebates on high-efficiency furnaces and AC units
• Rebates on insulation and air sealing
• Free home energy assessments
• Rebates on smart thermostats

Utility Programs

Many Wisconsin utilities offer additional incentives:

• We Energies
• Madison Gas and Electric
• Alliant Energy
• Xcel Energy

Check your utility's website for current offers—rebates can offset 10-20% of upgrade costs.

Federal Tax Credits

The Inflation Reduction Act provides tax credits for:

• Heat pump installation
• High-efficiency furnaces
• Insulation and air sealing
• Energy-efficient windows and doors

Measuring Your Progress

Track efficiency improvements:

• Compare utility bills year over year (adjust for weather differences)
• Monitor smart thermostat energy reports
• Schedule professional energy audit for comprehensive assessment

Professional Energy Assessment

A professional energy audit identifies your home's biggest efficiency opportunities:

• Blower door test for air leakage
• Infrared imaging for insulation gaps
• Duct leakage testing
• Equipment efficiency evaluation
• Prioritized recommendations

Many utilities subsidize audits, reducing cost to $100-200 for comprehensive assessment.
