So it sounds like:

1. Not go with the company who has 1 installer that does all the
installation, including the high voltage line.
2. Still consider the Sears.ca SEER 10 unit as I will only run the unit
for 3.5 months out of the year and it may not be worthwhile to fo rthe
the pricier Trane 15 Seer Unit.

Does this sound right?
