U.S. homeowners spent $139.1 billion on energy-related home improvements in one year 💡 A new Harvard Joint Center for Housing Studies paper breaks down where that money went.
✔️ 16.9 million homeowners (19.5%) did at least one energy-related project in 2023
✔️ Roofing led: $45.8 billion, averaging $11,040 per owner who did the work
✔️ HVAC was next: $40.4 billion, averaging $8,400
✔️ Windows and doors: $22.1 billion, averaging $5,610. Insulation: $3.5 billion, averaging $2,260
✔️ Older homes carry the most catch-up: 34.5% of owner-occupied homes built before 1960 still have single-pane windows, vs. 16.3% of homes built in 2000 or later
What this means for you: roofs and furnaces are the big-ticket items, so budget for them before they fail instead of after. If your house is older, windows, drafts and insulation are worth a look at the same time.
Which one is next on your list: roof, HVAC or windows? 👇
