rooftop A/C
#4

I’m chasing down a problem with my #4 AC unit. The problem is no cold air… 
Cleaned up the condenser and evaporator… the process reminded me what a mess these units are!
I’ve heard the same that you can’t go out and buy a new unit right now… Out of Stock… quick search shows this. 
I’ll get old #4 running again with a new capacitor but there is still a on going problem… When all four of these things are running we can’t hear ourselves think! 
I’d love to find a unit that is a step in the right direction using newer motor and fan technology and much quieter. 
If anyone can provide a recommendation I’d appreciate the info. 
I also wonder if four units that are AC/heat pumps are necessary. Does anyone run with only two? One in front and one in back? AquaHot works great so I’m assuming the heat pump is just a backup… educate me. 
The current unit I’m working on is a Duo-Therm 630516.321    15,000btu  single motor turning two vibrating squirrel cage fans… 
I’m hoping Newell has figured out a better mouse trap since my 05 was built. I was parked between two new Newells last weekend and could barely hear their AC units running. I’ve never been inside a new one when it’s 90* OAT.. 
Thanks! JK
