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...

23 calls in two days from this outfit.

Got call for them, doing airquality survey, said i won a prize. I'm betting is vacuum cleaner people, going to show me how their vacuum cleans my air .....

Said he was from Sterling Solutions asked about air quality and proceeded to asked if anyone smoked in the house if anyone had asthma. He asked how long living in house and asked if anyone what type of work we worked in and if we worked fulltime and how long.Can't remember name. Said might win prize and confirm number he had called me at. Just seem to ask more questions were asked off topic of air quality. My guess is vaccum sales and checking if we can afford the overpriced Sh_t.

A indian person from this number called and asked if I could answer a few questions, it would only take a minute of my time. I answered the first five or so questions then he asked my what I did for a living as a said I was a Mom the he asked what my husband did for a living. I informed him that i was not married, he then started to drill me about having a child and not being married. I asked if this was a problem for him, he said YES it is a problem. I asked why.. thats when he hung up on me. I tried to call the number back and it was out of service.

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.
