One additional thought about A/C. Some people when building and planning on A/C, desire massive amounts of airflow where the quantity is more important than the temperature, hence the double blower “Aussie” option.
Personally, I prefer the softer blow with colder air and here’s why.
Even with the single blower on high, the force of the air is high enough to break squelch on your intercom and create white noise in your headset by blowing on the headset mic, especially with four headset users in the airplane. It does get annoying after a bit requiring turning the fan down to mitigate. I have the Aerosport overhead with the Boeing style vents from Stein. Bill’s original overhead with the large minivan vents would be different.

I have the Flightline system and modified it quite a bit in partnership with John Strain with Kelly Aerospace to move the intake and exhaust for the condenser to the side skins. Without turning this into a "which is better," there are advantages to either system. I agree that A/C is a standard option for the 10. It makes flying so much more comfortable (I have it in the DA-40 I fly now) and a lot of non-flyers are more willing to go on an adventure being cool and comfortable.

Check out my build log for some of the modifications that I made. To Myron's point, either system you go with, there are limitations and requirements for any system to work efficiently. Airflow across the condenser and evaporator are key to success. It doesn't have to be crazy velocity, more about volume. I used 3" vents from Summit Racing that will provide plenty of flow while still providing some direction and are able to be closed off.

Default air conditioning

I had the original evaporator Bill sold and it didn't put out enough cooling air for me. I installed the larger evaporator and now get plenty of cooling air. I have two 4" flood vents on the back bulkhead which fills the cabin with cool air. I also supply air to the overhead duct with a 3" hose from the evaporator.

Something you might want to consider when wiring the evaporator, Bill uses 16-18 gauge wire to the evaporator fan. I used 22 gauge wire to 3 relays mounted on the evaporator shelf from the fan switch. I ran a fused wire directly from the battery to the relays for the evaporator fan. I have a 4th relay that runs a 3" axial duct fan to help push the air thru the overhead duct. This fan comes on when the fan switch is selected to high.
