Cut heating costs by up to 70%
Works to -22°F
Federal & state rebates available
Wisconsin winters are changing.
More wild temperature swings. More expensive utility bills. If you’re using baseboard electric heat, propane, or an aging furnace, you’re probably paying $200-300+ per month to stay warm—and that’s before we talk about cooling costs in our increasingly hot summers.
Heat pumps offer a better way—cutting energy costs by 50-70% while providing both heating and cooling from one efficient system.
At Ethos Green Power, we’ve been helping our neighbors across southwest Wisconsin make smart energy decisions since 2013. As a worker-owned cooperative based in Viroqua, we combine deep local expertise with honest pricing and a commitment to empowering our community through electrification. This guide explains everything you need to know about heat pumps in Wisconsin—how they work, what they cost, and whether they’re right for your home.
What Is a Heat Pump and How Does It Work?
Think of your refrigerator. It doesn’t “create cold”—it moves heat from inside the fridge to outside, which is why the back of your refrigerator feels warm. A heat pump works on the same principle, but it can reverse direction.
In winter, a heat pump extracts heat from outdoor air (yes, even cold air contains heat energy) and moves it inside your home. In summer, it reverses and removes heat from your home, acting like an air conditioner.
One system handles both heating and cooling.
Why this matters for Wisconsin:
Modern cold-climate heat pumps are specifically engineered for northern climates. Unlike older models that struggled below 30°F, today’s cold-climate units maintain full heating capacity down to around 5°F and continue operating (with reduced efficiency) down to -22°F or lower. This makes them viable for La Crosse, Vernon, Crawford, Richland, and Grant counties, where winter lows regularly hit single digits but rarely stay below -10°F for extended periods.
The efficiency advantage comes from the fact that moving heat requires far less energy than generating it. Electric baseboard heaters convert electricity to heat at roughly 100% efficiency—that sounds good until you realize heat pumps can deliver 200-300% efficiency by moving existing heat rather than creating it from scratch.
Types of Heat Pumps for Wisconsin Homes
Mini-Split (Ductless) Heat Pumps
A popular choice for Wisconsin homes. These systems don’t require ductwork—each indoor unit mounts on a wall and connects to an outdoor compressor via a small line set.
Best for:
- Homes without existing ductwork
- Additions, three-season rooms, converted garages
- Zone heating (heating only rooms you use)
- Replacing baseboard electric or propane
- Typical costs: $6,000-10,000 for single-zone; $10,000-18,000 for multi-zone systems.
Ducted Heat Pumps
If your home already has ductwork from a forced-air furnace, a ducted heat pump replaces your existing HVAC system.
Best for:
- Homes with existing ductwork in good condition
- Whole-home heating and cooling replacement
- New construction or major renovations
- Typical costs: $12,000-20,000+ depending on home size and system capacity.
Ground-Source (Geothermal) Heat Pumps
Geothermal systems extract heat from the ground rather than the air. Incredibly efficient but require significant upfront investment for underground loops.
Best for:
- New construction with suitable land
- Properties with acreage for horizontal loops
- Long-term homeowners seeking maximum efficiency
- Typical costs: $20,000-40,000+ installed. Higher upfront costs but lowest operating costs.
Ethos Recommendation
For most southwest Wisconsin homeowners, mini-split heat pumps offer the best balance of performance, cost, and installation simplicity. They’re particularly effective for homes currently using baseboard electric, propane, or homes adding conditioned space.
Heat Pumps vs. Traditional Wisconsin Heating Systems
How do heat pumps compare to what you’re probably using now? Here’s the real-world breakdown based on our installation experience across southwest Wisconsin:
| Heating System | Typical Annual Cost (1,500 sq ft) | Monthly Winter Average |
|---|---|---|
| Baseboard Electric | $2,800–3,500 | $280–350 |
| Propane (at $2.50/gal) | $2,200–2,800 | $225–275 |
| Natural Gas Furnace | $1,200–1,600 | $120–150 |
| Wood/Pellet Stove | $800–1,400 | $80–140 (plus labor) |
| Cold-Climate Heat Pump | $1,000–1,500 | $100–150 |
Note: Costs based on Xcel Energy rates (~$0.15/kWh, 2026 approved rate) and typical southwest Wisconsin heating loads. Your actual costs will vary based on home size, insulation, and temperature preferences.
The Biggest Winners
Baseboard Electric Replacement
If you’re currently heating with baseboard electric, a heat pump can cut your heating costs by 60-70%. We regularly see customers go from $280-350/month winter electric bills to $100-150/month with a properly sized heat pump system.
Three-Season Rooms and Additions
Many Wisconsin homes have three-season porches, converted garages, or additions that are expensive to heat. Running baseboard heat or trying to extend ductwork to these spaces often costs more than it’s worth. A single mini-split head can make these spaces comfortable year-round for less than $7,000 installed.
Cabins and Second Homes
Heat pumps are ideal for cabins and weekend properties because they can maintain a lower temperature efficiently when you’re away, then quickly bring spaces to comfort when you arrive. The cooling function also addresses increasingly common summer heat, and modern models can be controlled remotely via smartphone apps.
Cold-Climate Performance: Will It Work in a Wisconsin Winter?
This is the question we hear most often, and it deserves a clear answer: Yes, modern cold-climate heat pumps work in Wisconsin winters.
Cold-climate heat pumps use advanced compressor technology and enhanced refrigerants that allow them to extract heat from outdoor air even when temperatures drop well below freezing. Here’s what you need to know:
Performance at Different Temperatures
- 40°F to 20°F: Heat pumps operate at peak efficiency, delivering 250-350% efficiency (meaning every 1 kWh of electricity moves 2.5-3.5 kWh of heat).
- 20°F to 5°F: Performance remains strong, typically 200-250% efficiency. This covers the majority of Wisconsin winter days.
- 5°F to -5°F: Efficiency decreases but remains cost-effective compared to electric resistance heat, usually 150-200% efficiency.
- -5°F to -15°F: Heat pumps continue operating but may need supplemental heat during extended cold snaps.
- Below -15°F: Most systems remain operational but at reduced capacity. Backup heat may be necessary.
Southwest Wisconsin reality check: According to NOAA climate data, SW Wisconsin averages about 21 days per winter below 0°F, and extended periods below -10°F are rare. This means heat pumps operate efficiently for 95%+ of the heating season.
The Backup Heat Question
Many customers ask if they need backup heat. The answer depends on your existing system and comfort preferences:
If you have an existing propane or natural gas furnace: Keep it as backup. The heat pump will handle 90-95% of your heating, with the furnace only running during extreme cold or if the heat pump needs service.
If you’re replacing baseboard heat: Most homes can rely solely on heat pumps, but some customers choose to keep one or two baseboard units in rarely used rooms as emergency backup.
If you’re off-grid or concerned about power outages: A wood stove or propane heater makes sense as emergency backup regardless of your primary heating system.
Ethos installs Fujitsu cold-climate heat pumps— specifically engineered for northern climates and backed by strong warranties. We can size systems based on your home’s actual heat loss calculations, not generic estimates, ensuring reliable comfort even in the coldest weather.
Heat Pump Rebates and Incentives in Wisconsin
Heat pumpsWisconsin offers two distinct rebate pathways for heat pump installations, and understanding which you qualify for can mean the difference between modest savings and covering most of your installation cost.
Path 1: Focus on Energy Standard Rebates (All Customers)
Focus on Energy is Wisconsin’s statewide energy efficiency program, offering instant discounts for qualifying heat pump installations. These rebates are available to all residential customers regardless of income.
Important: Rebates are per system (based on outdoor unit efficiency), not per indoor head. A multi-zone mini-split with four indoor units receives the same rebate as a single-zone system at the same efficiency tier.
| Efficiency Tier | Requirements | Standard Rebate | Income-Qualified Bonus |
|---|---|---|---|
| Tier 1 | SEER2 ≥15.2, HSPF2 ≥8.1 | $400 | +$200 ($600 total) |
| Tier 2 | SEER2 ≥15.2, HSPF2 ≥8.5 | $500 | +$200 ($700 total) |
| Tier 3 | SEER2 ≥16.0, HSPF2 ≥9.0 | $600 | +$200 ($800 total) |
| Tier 4 | SEER2 ≥16.0, HSPF2 ≥10.0 | $700 | +$200 ($900 total) |
Propane Replacement Bonus: If you’re replacing a propane heating system, add $100-$150 (standard) or $300-$350 (income-qualified).
How instant discounts work: Unlike traditional mail-in rebates, Focus on Energy discounts appear directly on your contractor’s invoice. No application forms, no waiting—the reduced price shows immediately on your final invoice.
Path 2: HEAR Program (Income-Qualified) — The Big Opportunity
The Home Electrification and Appliance Rebate (HEAR) program offers dramatically larger benefits—but only for households earning less than 150% of Area Median Income (AMI).
This is the headline opportunity most people don’t know about.
| Household Income | Project Cost Coverage | Heat Pump Rebate | Electrical Upgrades | Total Maximum |
|---|---|---|---|---|
| Below 80% AMI | 100% of costs | Up to $8,000 | Up to $6,500 | $14,000/household |
| 80-150% AMI | 50% of costs | Up to $8,000 | Up to $6,500 | $14,000/household |
| Above 150% AMI | Not eligible | — | — | — |
What does this mean in real dollars? A family of four in Vernon County earning $75,000 (approximately 80% AMI) could qualify for 100% coverage of their heat pump installation up to $8,000—potentially paying almost nothing out of pocket for a system that typically costs $10,000-12,000.
Wisconsin received $74.5 million in federal Inflation Reduction Act funding for this program. It continues until funds are exhausted—first come, first served.
Critical: HEAR rebates are NOT retroactive. You must complete income qualification before purchasing equipment. Use the Focus on Energy income qualification tool at focusonenergy.com/ira-hear to check eligibility.

Common Questions About Heat Pumps in Wisconsin
How long do heat pumps last?
Quality heat pumps typically last 15-20 years with proper maintenance. Outdoor units are designed to withstand harsh weather, and indoor mini-split heads often last even longer since they have fewer mechanical components. Regular filter cleaning and annual professional maintenance maximizes lifespan.
Are heat pumps noisy?
Modern heat pumps are remarkably quiet. Indoor mini-split units operate at 19-30 decibels—quieter than a whisper. Outdoor units generate 50-60 decibels when running, similar to a normal conversation. Proper installation and quality equipment minimize operational noise.
What maintenance do heat pumps require?
Monthly: Clean or rinse indoor unit air filters (takes 5 minutes)
Annually: Professional inspection including refrigerant check, electrical connections, outdoor coil cleaning, and condensate drain verification
As needed: Clear snow, ice, or debris from outdoor unit (rare but important during heavy snow)
Annual professional maintenance typically costs $150-250 and is essential for warranty compliance and optimal efficiency.
Can I install a heat pump myself?
Heat pump installation requires EPA Section 608 certification for refrigerant handling, electrical licensing for circuit installation, and specialized equipment for vacuum and charging procedures. DIY installation voids manufacturer warranties and may violate local codes. Professional installation ensures proper sizing, safe electrical work, and warranty protection.
Will my electrical service support a heat pump?
Most modern Wisconsin homes have sufficient electrical service (200 amp) for heat pump installation. Older homes with 100 amp service may need evaluation—sometimes a load management panel allows heat pump installation without full service upgrades. We assess electrical capacity during the home evaluation and discuss any needed upgrades upfront.
Do heat pumps work with solar panels?
Yes, and they’re an excellent combination. Heat pumps use electricity efficiently, making them ideal partners for solar systems. A typical 6 kW solar array can offset most or all of a heat pump’s annual electricity consumption. As a solar and heat pump installer, Ethos can design integrated systems that maximize energy independence.
Can I combine Focus on Energy and HEAR rebates?
Yes. You can receive both Focus on Energy instant discounts and HEAR program rebates for the same equipment. Local utility rebates can also be stacked with both programs.
How is my income calculated for qualifying for rebates?
If you’re close to the 150% AMI threshold, income is calculated based on household size—larger households have higher thresholds
Some deductions may apply to gross income calculations
Contact Focus on Energy at 800-762-7077 to clarify how income is calculated for your situation
What if incentive programs change or end?
Focus on Energy: Ongoing utility-funded program; amounts may change annually but program expected to continue
HEAR program: Continues until Wisconsin’s $74.5 million allocation is exhausted—first-come, first-served
We recommend installing sooner rather than later to lock in current incentive levels. The HEAR program represents a one-time funding opportunity that won’t be repeated once funds are depleted.
