I have checked around and can't get an HVAC company to "only commission" a unit. They only want the whole job---at 2.5-3x the unit cost. hahahahaha
Example: Your unit installed here=$4700=no way in haydezzz
Question(s): Did the tech have a company backing, or is just a tech with EPA docs ok?
Did you buy from King_____s, and did they have any issues?
What happened to you is EXACTLY what is holding me up, ie nothing to do with the install/commis. Heck, I'm wanting to hack the thing someday, but it's their spooky "new" compressor/pcboard/etc. that I don't trust. I would hate to eat a $2000 bill over a bad part.
For now I just want to install as built. I want to see how/if it works for my app. If it proves itself,and needs it, I'll move to hacking/or a GS/Solar/?? assist method to improve its performance.
