TimLee is not that expensive, its just a cheap reversing valve. I used to this back in the '70s to window units.. yes I took AC in High School. I still think you guys should just buck up or move to Florida.
The expensive option would be an multistage heat pump system using CO2 as the freon, but it would be effective down to -30° C
