How we research

We show the source, the date, and what still needs a check.

Programs change. Service areas can cross. We do not guess when we are not sure. We make it easy to find the official source.

Start with official sources

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

Record the check date

A clear date helps you see if the facts may be old.

Keep facts and estimates apart

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

What we record

The facts that can change your choice

For each program, we check its status, who can apply, covered equipment, needed approval, due dates, money limits, and contact details.
