Our research standard

We show the source, the date, and what still needs checking.

Programs change. Service areas overlap. We avoid false certainty and make it easy to reach the official source.

Start with official sources

We prefer utility, city, state, and program documents.

Record the check date

A clear date helps you judge whether information may be stale.

Separate facts from estimates

Verified facts, possible matches, and calculator estimates use different labels.

What we record

The details that change a decision

For each program, we look for status, eligible customers, covered equipment, pre-approval, deadlines, funding limits, and official contact information.
