Question 1

How long does a home energy audit take?

Accepted Answer

Enerly's virtual home energy audit takes 5–10 minutes. You answer questions about your home's heating, cooling, insulation, water heater, lighting, and appliances. No contractor visit or physical inspection is required.

Question 2

Is Enerly really free?

Accepted Answer

Yes. The full 7-step home energy audit, your efficiency score, and your top upgrade recommendations are completely free. Enerly Premium ($5 one-time) unlocks your complete ranked list, full rebate matches, and peer comparison data.

Question 3

What is a good home energy efficiency score?

Accepted Answer

Enerly scores homes from 0 to 100. Scores of 75 or above indicate a well-performing home with modern systems and good insulation. Scores of 40–74 are average — most U.S. homes built before 2000 fall in this range. Scores below 40 indicate significant efficiency opportunities, typically older HVAC systems, poor insulation, or single-pane windows.

Question 4

What is the most impactful home energy upgrade?

Accepted Answer

For most homes built before 2000, attic insulation plus air sealing is the single highest-ROI upgrade, typically paying back in 3–5 years and reducing heating and cooling costs by 15–25%. For homes with older gas furnaces, switching to a heat pump can save $400–$1,200 per year and qualifies for up to $8,000 in HEEHRA rebates plus the federal home improvement tax credit.

Question 5

What rebates are available for home energy upgrades?

Accepted Answer

Federal incentives include the federal home improvement tax credit (30% back on heat pumps, insulation, and windows for all income levels) and HEEHRA rebates (up to $8,000 for heat pumps for income-qualifying households). Most states and utilities offer additional programs. Enerly matches you to all available incentives by ZIP code.

Question 6

Do I need a contractor to complete Enerly?

Accepted Answer

No. Enerly is a virtual audit you complete yourself in 5–10 minutes. You answer questions about your existing home systems — no measurements, no equipment, no contractor needed. Our recommendations tell you exactly what to discuss with a contractor if you decide to move forward.
