This is where bad air conditioners go when they misbehave. Ran across this one this morning.
The old Lennox on the right is disco'd. Apparently, when it died they just set the Carrier next to it and ducted it in.
As if it didnt have enough of a challenge to begin with. Amazingly, the original compressor still runs. Didnt check pressures to see if it actually pumps though.
AC unit didnt have heat. No problem, there's an easy solution. No need for dampers, it'll work just fine.
The front unit isnt much better.
Atleast the neighbors were smart enough to ditch the attic equipment.
