Also got a call re free HVAC inspection and air ducks.  Did not sound at all professional.  I'd be very suspicious.

Similar to the other posts, I also received a call offering free HVAC estimates. Coincidently, I have been looking for a new HVAC system (through what I thought were reputable companies) and am wondering if perhaps that's how my number was passed along to these people. I believe the caller identified himself as being from a company called "Clean Air".

the call sounded very suspicious, asking for Mr......., and I told that person is not here now and just said: i will call another time. and hang up.didn't give any time to ask what was about, I tryed to call and nobody answers, and when answer they hang up inmediatly.   Sounds like a scam.

Called to sell a free inspection of HVAC and air ducts. Didn't sound very professional and there was a loud, annoying buzzing in the background. Or maybe that was the salesperson.
