I went with the mini-split because the roof line was lower the weight
was lower the cost (on sale) was lower I thought the noise would be lower and I was building my FrankenScamp the way I wanted it.
It has worked out well for us.
While there are compromises in all things.
It almost seems that the unit is oversized since it is more efficient.
In the heating phase we crack the vent open for better operation.
Last night it was 38*F and we had it open about an inch.
I looked as the coffee maker and heat pump were both running and my power meter showed 12 amps of 120 .
If you have to get someone else to do the physical mounting it is probably not for you.
Our old Scamp
did not have the roof reinforcing so this fit the bill.
