The Empty Wall
This wall is opposite the space he uses for exercise. It's the perfect location because the air will blow across the garage towards his gym area. His car will also be more comfortable when he gets into it in the morning.
Installed indoor unit
Here's the finished product inside. It looks great up there! You can see the wireless remote control mounted on the wall. What you can't see is the tubing and wiring that go thru the wall in back of this unit to the heat pump outside.
Outside Before the Installation
No, that's not the new heat pump! That's a 12-year old mini-split air conditioner that cools the art studio on the second floor above the garage.
New Outdoor heat Pump
There's the new one! The brown enclosure hides the piping and wiring that connect the outdoor unit to the indoor unit on the wall. You can also see the conduit and wiring in the small galvanized pipe. This carries power from the circuit breaker panel on the opposite side of the garage.
