Insulation Upgrades
Proper insulation and air sealing in a home improves comfort, reduces energy waste, and helps heating and cooling upgrades perform better.

But the reality is that it's far more common for Minneapolis & St. Paul homes to be underinsulated, creating high utility bills, indoor drafts, ice dams, and uneven indoor temperatures.
That's why, at Green Spirit Home Performance, insulation and air sealing are an essential part of our services. When you need a partner for improving your Twin Cities home and navigating whole-home upgrades, call Green Spirit!
Why Insulation Matters in a Whole-Home Plan
Without high performing insulation and air sealing, even the best new HVAC system can underperform.
At Green Spirit, we:
- Assess insulation levels and air leakage as part of your home assessment
- Recommend insulation upgrades that complement your heating and cooling system
- Consider how insulation will impact heat pump sizing, equipment efficiency, and future energy bills
- Help you prioritize improvements that provide comfort, savings, and value
Many homeowners take the opportunity to upgrade their insulation alongside new HVAC installation, because the two systems work better when planned together.
Expert Work in Older Homes
Upgrading the insulation in older homes, like the Victorians and early 20th-century houses common to the Twin Cities, isn't always easy. These homes weren't built with modern insulation in mind, and many HVAC contractors simply don't understand building science well enough to understand the impact of insulation on a heating and cooling system.
But Green Spirit specializes in older Twin Cities homes. We know how to:
- Upgrade insulation without compromising character
- Navigate hidden air leaks, plaster walls, and irregular framing
- Improve comfort and reduce drafts in ways that make a noticeable difference
A Home Is a System (And We Plan It That Way!)
At Green Spirit, we look at your entire home, not just one part of it. That's what makes our approach different.
We understand how one upgrade affects another. For example:
- Better insulation and air sealing makes your home tighter
- A tighter home may need improved ventilation
- HVAC sizing may need to be adjusted, especially if you're upgrading to a heat pump
Because we offer both insulation and HVAC services, we can balance and optimize these systems as part of a single plan. You won't need to coordinate between multiple contractors. We handle it all, often working with multiple skilled local partners while providing you with one point of contact and clear communication.
Our Insulation Services Can Include:
- Old Insulation Removal
- Attic Insulation
- Wall Insulation (including hard-to-reach spaces)
- Basement & Crawlspace Insulation
- Air Sealing (doors, windows, penetrations, rim joists)
Every project is designed with your home's age, layout, energy use, and future goals in mind.
Rebates, Incentives & Financing
Insulation and air sealing upgrades often qualify for significant rebates and incentives, including:
- Xcel Energy and CenterPoint Energy rebates
- Forthcoming Home Energy Rebates
Green Spirit will help you identify what's available, time your project to maximize benefits, and explore financing options when needed.
