Heat Pumps & Ductless Mini Splits in the Fox Valley
Heat pumps finally make sense in Wisconsin, if they are the right heat pump, sized honestly, with a real plan for the coldest nights. We install cold-climate systems and ductless mini splits, and we will tell you plainly when your house is not a good candidate.
Common Signs You Need Heat Pumps & Ductless Mini Splits
⚠️ A room the system never reaches
Bonus room over the garage, finished attic, three-season porch. A ductless head fixes what duct surgery cannot.
⚠️ Boiler home that wants AC
Radiator heat and no ducts used to mean window units. Mini splits ended that.
⚠️ Electric baseboard bills
Baseboard resistance heat is the most expensive heat you can buy. A mini split delivers the same warmth for a fraction of the energy.
⚠️ Replacing AC anyway
If the condenser is due, a cold-climate heat pump can replace it and carry most of the heating season too.
⚠️ Interest in dual fuel
Heat pump for the bulk of the season, gas furnace for the brutal nights. The setup that fits Wisconsin best.
⚠️ Shop, office, or addition
Spaces the main system was never designed for, conditioned independently with their own control.
When It Is Urgent
Heat pump projects are planned work. The urgency is seasonal: systems ordered and installed in shoulder season are ready before the July heat or the January cold, and rebate windows favor the planners. An existing heat pump that has lost heating in winter gets treated like any no-heat call, with full urgency.
The honest version of the heat pump conversation
Modern cold-climate heat pumps hold useful capacity well below zero, which covers most Fox Valley winter days. But design temperature here is around 11 below, and a system needs a plan for those nights: either a dual-fuel setup that hands off to a gas furnace, or electric backup sized for the worst week of January. Anyone selling you a heat pump without that conversation is selling, not engineering.
Where mini splits shine
Ductless systems are the right answer more often than people think: the bonus room over the garage that never matches the rest of the house, three-season rooms being pushed to four, older boiler-heated homes that want air conditioning without duct surgery, and shop or office spaces. One outdoor unit can feed multiple rooms, each with its own control.
Installation quality shows up in February
Cold-climate performance depends on details: mounting the outdoor unit above snow depth, proper defrost drainage so it does not build an ice pedestal, line sets sized and insulated correctly, and controls configured for the changeover strategy your house needs. These are the things we sweat so the system just works when the temperature drops.
How We Diagnose
- 1Assess whether your house is a good candidate at all, and say so plainly if it is not
- 2Model the heating load against real cold-climate capacity curves, not brochure numbers
- 3Design the cold-night plan: dual fuel handoff or properly sized backup
- 4Plan outdoor unit mounting above snow depth with real defrost drainage
- 5Size line sets and configure controls for the changeover strategy your house needs
Our Process
- 1Honest candidacy assessment and a written quote with the cold-night plan spelled out
- 2Mount the outdoor unit above snow depth, on brackets or a proper stand
- 3Run line sets sized and insulated correctly, penetrations sealed
- 4Commission with measured refrigerant charge and verified heating performance
- 5Configure controls and walk you through how the system behaves in deep cold
💰 Pricing Guide
- •Single zone versus multi-zone, and how many heads
- •Cold-climate equipment tier, which determines low-temperature capacity
- •Dual-fuel integration with an existing furnace where that is the right design
- •Mounting, line set routing, and electrical work
- •Utility and Focus on Energy incentives on qualifying systems
We publish the factors, not made-up averages. You get a written number before work starts, and the number on the estimate is the number on the invoice.
📋 From the Field
- The room we get asked about most:
- The bonus room over the garage that is an icebox in February and an oven in July, no matter what the thermostat says.
- Why it happens:
- Long duct runs, garage-exposed floors, and a system sized for the rest of the house. More duct rarely fixes it.
- What we do:
- A single ductless head with its own control, mounted cleanly, condensate handled properly. The room joins the house year-round.
- The honest part:
- We also tell people when a mini split is not the answer, because a system that disappoints in February helps nobody.
Why Palisades for Heat Pumps & Ductless Mini Splits

- ✓Dual-fuel designs that hand off to gas exactly when the math says to
- ✓Mounting details that survive Wisconsin: snow height, defrost drainage, no ice pedestals
- ✓Multi-zone design experience for whole-house ductless where the house suits it
- ✓Plain answers about candidacy before anyone spends money
📍 Local Perspective
Modern cold-climate heat pumps hold useful capacity well below zero, which covers most Fox Valley winter days. Design temperature here is around 11 below, though, and the systems that satisfy their owners are the ones installed with a real plan for those nights. That plan is the difference between engineering and selling.
Heat Pumps & Ductless Mini Splits FAQs
Do heat pumps really work in Wisconsin winters?›
Good cold-climate models, yes, down to well below zero with reduced capacity. The design question is what covers the handful of coldest nights. We set that up as dual-fuel or sized electric backup, per house.
What does a mini split cost to run?›
For the spaces they serve they are usually the cheapest heat and cooling per delivered BTU you can buy, especially versus electric baseboard or window units. Exact numbers depend on your rates and usage; we will walk the math with you.
Can a mini split heat a whole house?›
A multi-zone system can, in the right house. Tighter, smaller homes do well. Large or leaky homes usually want a hybrid approach. We will tell you which yours is before anyone spends money.
