Repair planning guide

Energy efficiency upgrade planning

How to plan insulation, air sealing, HVAC, windows, appliances, and electrical-readiness upgrades, with links to official DOE/Energy.gov and ENERGY STAR guidance. No unsourced savings claims.

Overview

Energy upgrades are most effective when planned together: sealing air leaks and improving insulation before resizing heating and cooling equipment, for example. This guide outlines common upgrade categories and points to official U.S. Department of Energy (Energy.gov) and ENERGY STAR resources. It does not claim a specific dollar or percentage saving — those depend on your home, climate, and energy prices, and should come from a professional energy assessment.

Start with the envelope

Energy.gov's general guidance treats air sealing and insulation as foundational because they reduce the load that heating and cooling equipment must meet. A professional home energy assessment can prioritize these for your specific home.

  • Air sealing — reduce drafts and uncontrolled air leakage.
  • Insulation — attic, walls, and floors as appropriate to your climate.
  • HVAC — service, and size or upgrade equipment after the envelope is addressed.
  • Windows and doors — repair, weatherstrip, or upgrade where cost-effective.
  • Appliances — look for ENERGY STAR-certified models when replacing.
  • Electrical readiness — plan panel and circuit capacity if adding electric equipment.

Get an energy assessment

A professional home energy assessment (sometimes called an energy audit) identifies where your home loses energy and which measures matter most. It is a better basis for decisions than generic rules of thumb.

Savings claims need a source

This guide does not state how much you will save. Any savings figure should come from an official source or a professional assessment specific to your home. Where a local savings number would go, treat it as: Data not yet verified.

Planning checklist

  • Schedule a professional home energy assessment before major upgrades.
  • Prioritize air sealing and insulation before resizing HVAC.
  • Service heating and cooling equipment on a regular schedule.
  • Look for ENERGY STAR certification when replacing appliances or equipment.
  • Plan electrical capacity before adding electric heating, cooking, or EV charging.
  • Keep manufacturer documentation and assessment reports together.

What to verify locally

Local rules vary and change. Confirm these with the right local authority.

  • Available local, state, or utility efficiency programs and current eligibility.
  • Whether electrical or HVAC changes require permits and licensed trades.
  • Requirements vary by location. Verify with your local building department.

When to contact a licensed professional

  • Electrical panel or circuit upgrades.
  • HVAC sizing, replacement, or fuel-switching.
  • Insulation in spaces with moisture, knob-and-tube wiring, or combustion appliances.

Documentation to collect

  • Your home energy assessment report.
  • Current utility bills for baseline context.
  • Equipment model numbers and manufacturer documentation.
  • Any rebate or program paperwork.
