 Your predicate isn't true, so your conclusion doesn't follow.
 

2. In any case, since heat pumps run on electricity, the A/C is not
"free" at all.

However, the compressor required for air conditioning comes with
all heat pump furnaces, so the user doesn't need to purchase a
separate compressor.  That's the 'free' part.

Given Seattle's climate it's more than likely that the electricity used running the heat pump year-around will cost less than what the oil costs for heating alone.

and suggests that the push to heat pumps is a bit ... dishonest.

 Not at all.

Less dishonest than most marketing.
