I got a creepily similar call just a moment ago.
They said that same thing about an environmental survey but asked about energy efficiency instead of air quality. "Call Somebody Inc" showed up on my caller id, along with a local phone number. They wanted to know things about the size of our home, gas or electric, if our power bill was average, etc. The young woman on the other end of the line was actually nice, so I was compliant. She also mentioned something about calling me back about a gift. That's what tipped me off to something seeming fishy. But the strange thing here is that I got this call in Birmingham, AL. There's something odd about it all...

these people have called me 14 times in the last 2 days

23 calls in two days from this outfit.

Kind of strange - but this number called us 3 times yesterday (answered it the first time and we identified them as a telemarketer, but husband couldn't remember the company's name).  We hung up on them mid-way through.  They called back at least twice after that within a few hours.  Today, they called 2 or 3 times again.
