I don't even know how to talk HVAC but how many square feet can this thing heat and cool? A "tiny house" is only about 300 sq ft. So $1760 plus solar panels seems a bit pricey for that application. I have a 720 sq foot frame house and am considering options for heat. I use a large window A/C which is working fine for the times when it's over 80 at night.
Use $4000 completely installed with 4 panels for an example
subtract 30% federal tax incentive ($1200) $2800 total
SEER +72 efficiency daytime and 22 night
Running on pennies or for free
Designed after PR Hurricane to run independent of grid for safety
VS
$2350 for SEER 16 junk
no tax cred
doesnt work if the grids off
So, Yes the value is way there for an extra few hundred bucks for sure
