I have received dozens of calls from Sears offering to inspect my furnace (sometimes saying that they'd be working in my neighbourhood, then later asking where I live).  I've always told them to put me on the Do Not Call list and they say they will but I still keep getting calls.  The calls come from a local Sears so I suspect they don't even realize there are telemarketing rules.  Now I just add their number to call blocking.

Please delete my name from your call list.  Your telephone manners are rude to say the least

This is Sears offering a free heating system inspection.
