In a previous column, I pointed out that making your home more energy efficient can save you money immediately if you finance the improvements, because the monthly payments could be less than your monthly savings. The recently enacted Inflation Reduction Act has some very generous tax credits and rebates that make such improvements even more practical and affordable. My intention this week is to give you a “roadmap” for doing so.
The logical starting point is to hire a professional to do an energy audit of your home — to identify the “low-hanging fruit,” meaning the quickest and easiest changes you can make or improvements you can install that will give you the most “bang for your buck.”
That low-hanging fruit is typically better insulation, and the energy auditor normally begins by performing a blower door test of your home. That involves installing a computer-calibrated fan in a doorway which sucks air out of your house. By depressurizing your home in this manner while all your other windows and doors are closed, the auditor can identify all the leaks which allow cold air into your home in the winter. That way you know where to caulk to make your home less “leaky.”
When it’s cold outside, the auditor can use an infrared camera pointed at your walls and ceilings to assess where you could improve your in-wall and in-ceiling insulation.
You’ll get a written report from you energy auditor with suggestions of things to do and how much benefit you will get from making those changes, whether it’s blowing insulation into your attic and walls, replacing your old gas furnaces and gas water heaters with heat pump versions, or installing better windows. Most recommended improvements will earn you a 30% tax credit under the Inflation Reduction Act.
There are more “roadmap” items, but you will learn about most of them by attending the Oct. 1 tour of green homes. See the blog post.
If you or someone your know is an energy auditor, let me know. We expect big demand for your services!
