I wonder how many thermostats are purchased every year that did NOT need to
be purchased?

Why is is that everyone thinks "My furnace isn't working! My thermostat must
be broke!" That's
almost like having a light bulb burn out and then going out and buying a new
switch for the wall.

In looking at the subject line, a better question would be:

"Why is that so many customers wait until the coldest night to
request/demand service on their
furnace when they were told at the end of the LAST heating season that the
furnace was running
on borrowed time yet they expect us to 'COME OUT tHERE RIGHT NOW! I HAVE
BEEN
A CUSTOMER FOR 100 YEARS AND I AM GOING TO TAKE MY BUSINESS ELSEWHERE
IF I HAVE TO WAIT MORE THAN 10 MINUTES!!!!!' Which they WILL call every 10
or 15
minutes....."

Then again, I don't think that will fit on a subject line, but you get my
drift...
