The unit worked as expected. Took the chill off, but, would never be considered a replacement for the furnace.
I used the Coleman-Mach "kit" designed for my AC unit, as recommended by the Tech Rep at Coleman-Mach. I also had to change the thermostat to one that had the option for Elec. Heat. (I decided to go with the digital unit, since I was upgrading.) In order to install the whole system, I had to run an extra wire from the thermostat to the AC unit. That part took FAR longer than adding the heat kit or installing the new thermostat.
