Buds can instal but I had it installed by my mechanic. I think the complete unit is $2100 not labor to instal. Took my guy close to 2 full days to instal.
Look at their website.
Also they can refurbish you current unit with all new modern parts. A friend in Roanoke is doing the refurbish now, his old A/C just wasn’t cold enough on hot days. He drives his Pagoda every day to work.
