Stack Savings with Federal Tax Credits + Affordable Financing
By combining Maine energy rebates, federal tax credits, and affordable financing, homeowners from Portland to Rockland can save thousands on home efficiency upgrades. You may also qualify for federal tax credits up to $1,200 per year for insulation and air sealing upgrades.
And if you need help covering the remainder, Evergreen can connect you with financing through:
- Efficiency Maine’s Green Bank
- National Energy Improvement Fund (NEIF)
With monthly payments as low as $50, upgrading your home with Evergreen is more affordable than ever.
Thinking About a Heat Pump?
You may have heard about Efficiency Maine rebates available for installing ductless mini splits and ducted heat pumps, too.
While Evergreen doesn’t install heat pumps, we do something just as important: We prepare your home to get the most from a new heat pump by sealing air leaks and adding insulation. So if you’re considering heat pump installation for your Maine home, Evergreen is your guide to creating a house that’s truly heat pump-ready.
