I'm about halfway through an addition project on my house (new master
bedroom) and extending the existing ductwork is just not a good option.
I'm strongly leaning toward installing a mini-split system to handle
the heating and cooling for this new room.
The addition is about 350 square feet and is on the second floor (the
space below and through one long ajoining wall is heated and cooled by
my current forced air system). I live in central lower Michigan, so it
will be cold this winter for sure - probably averaging low to mid 30's
in January and February and can easily hit zero or less on cold nights.
Forgive the lack of question marks below - my keyboard is messed up and
that key doesn't work...
Am I correct in assuming that a "normal" mini-split with no auxiliary
electric heating is a bad choice for me. I've seen some decent looking
mini-split deals on Ebay, but none that I've seen specifically mention
auxiliary or back-up heat. I could probably install a simple baseboard
heater as a back-up (wife would just love the extra ugliness, I'm sure)
- would the mini-split sit there and run incessantly trying to generate
heat when the exterior unit is too cold to function, or do these units
shut themselves down when the outside ambient temp is too cold to work.
Anyone know where to buy a decent mini-split with aux heat online.
I've talked to some local hvac guys, but all look at me like a man from
the moon when I mention mini-splits (this is forced air, woodstove, or
corn burner territory).
