If that sounds like you, you’re not alone. In 2025, there are more opportunities than ever to save money while upgrading your home’s efficiency thanks to state and local rebates, federal tax incentives, and smarter remodeling options.

Why Energy-Efficient Remodeling Matters in Marathon County
Let’s face it: Wisconsin weather is no joke. From subzero temps in February to sweltering humidity in July, your home goes through a lot. And if your insulation, windows, or HVAC system isn’t up to par, you’re probably paying more than you should be just to stay comfortable.
Energy-efficient remodeling isn’t just about being environmentally responsible (though that’s a big plus). It’s about comfort, cost savings, and long-term value. Plus, thanks to updated state and federal programs in 2025, the financial return on energy upgrades is better than ever.

Most Impactful Energy-Efficient Remodeling Upgrades
Not all upgrades deliver the same value. Here’s where to focus first:
1. Insulation & Air Sealing
Proper insulation is the low-hanging fruit of energy efficiency. Many older homes in Marathon County lack adequate attic or wall insulation.
Proper attic insulation can reduce heating costs by up to 25%, making your home more energy-efficient and comfortable. Additionally, air sealing helps eliminate cold drafts and prevents heat loss around doors and windows, further enhancing your home’s warmth and reducing energy waste.
2. High-Efficiency Windows & Doors
Replacing single-pane or poorly insulated windows can dramatically improve comfort.
If you’re looking to upgrade your windows, consider choosing ENERGY STAR-rated models. Not only do these energy-efficient windows help reduce energy costs, but rebates may also be available for qualifying models, making them an even smarter investment for your home.
3. Heat Pumps (Ducted or Ductless)
Heat pumps work incredibly well in Wisconsin’s climate, even during freezing temperatures.
Rebates and tax credits will be available in 2025, offering significant savings for energy-efficient upgrades. Dual heating and cooling systems are a great option, as they help reduce overall energy consumption while keeping your home comfortable year-round.
4. Smart Thermostats
These little devices make a huge difference in energy savings and comfort.
Take control directly from your phone and let the system learn your habits to optimize usage for maximum efficiency.
5. Solar Panels (If You’re Ready to Go Big)
While not for everyone, solar can be a game-changer, especially if you plan to stay in your home long-term. Federal tax credits cover up to 30% of the cost.
Local Climate Considerations: Why Marathon County Homes Need Special Attention
Marathon County sits in Climate Zone 6, meaning:
When dealing with extreme cold, it’s essential to use materials and systems specifically rated for such conditions. Heating efficiency becomes a top priority, far outweighing the need for cooling. Additionally, moisture control is crucial to prevent issues like mold growth and structural damage, ensuring durability and long-term performance.
Any remodeling plan should account for these regional realities, especially if your home was built before 1980, when insulation standards were far lower than today.

Rebates are instant or mailed cash-back offers; tax credits reduce the amount you owe at tax time.
