4430 AC upgrade

[midTNDEERE]

Due to having to replace rebuilt compressors twice in the last 6-7 years, I'm looking into upgrading the AC on my 4430 and have a few questions that
I'm hoping some of you can answer. I'm considering changing the compressor from the original A6 Delco style to a Sanden compressor. Is there
anything I need to pay special attention to when doing this? Pulley diameter or anything else? I'm also wanting to upgrade the condenser to a high
efficiency condenser. Has anyone else done this? Is it worth the extra cost? I've been talking with an AP Air distributor and it appears they have
everything I need to change all lines, change compressor styles and upgrade condensor. Is AP Air a reputable business? How hard is it to change all
the lines? Any tips on changing the lines going up the cab? Do I need to change the evaporator too? It looks like the kit comes with a new expansion
valve and dryer. Any tips and shared experiences are greatly appreciated.

AP Air is a reputable business. My 4255 AC cools good in Texas heat with a Sanden compressor utilizing 134A refrigerant & original condenser & all original hoses except the 2 that attach to compressor. I'll try to remember to measure AC compressor pulley diameter.

I have used they're conversion compressor kits on my tractors work good as for the condenser if you're high side pressure is high and your not getting enough cooling in the cab need to change it. It just depends on the tractor. As for the corner post lines if you're tires are set in narrow have fun if you're a drinking man stock up.

I appreciate everyone's response. The high side has always run a little higher than what I'd like thus the reason for wanting to change the condenser. That's always been with a rebuilt A6 compressor from my local auto part stores. I've always been resistant to change the compressor to Sanden because the auto store has a lifetime warranty on the A6 compressor but now I'm tired of it going out right in the middle of hay season. The tires are set about mid-way out. Hopefully it'll be a six pack or less job.
