US Electric - states that this is a "public service" promotion to determine if your home qualifies for an energy credit
HA

They also called me from this number but the call could not b returned. Sounds like a scam to me.

Claimed to be with USA Electric (which I could not find online anywhere).  Said they wanted to do free inspection to save us up to 50% on energy costs and get $3800 from federal gov't.  When they got to the question about credit and I told them ours was poor, suddenly he was unable to schedule an appt at any time over the next 3 weeks. Bet I won't get another call from them!  Number is not reachable when tried to call back. Sounds like they are up to no good.

Definitely a scam.  They called twice and when I asked for credentials they hung up.
