Oil bills have climbed every year.

Maine heating oil climbed from $2.65/gal in 2010 to $4.10+/gal by 2025. Weatherization cuts your fuel usage by 25-35% on day one, so your bill drops by that much before the next price hike lands.

06 · Questions Homeowners Ask

The honest FAQ.

Actual questions that come up in the first installer conversation, answered for a typical Maine homeowner in 2026.

Should I do weatherization before or after heat pump?

Before. A well-insulated home needs a smaller heat pump, which runs more efficiently, dehumidifies better, and lasts longer. The right-sizing benefit alone is often the biggest comfort win on the project, and your Score sequences the order for you.

Is the home energy assessment free?

For income-qualified households: yes. Market-rate customers may have a small assessment fee that gets rebated upon completing qualifying work.
