So Saturday morning my boss phones me and gives me an address. Tells me it's a 20 ton Carrier RTU new account.
I said "cool " easy money.
This is what I find.
It's a 1985 Carrier 20 ton package unit. Actually they're not difficult to trouble shoot but good luck getting those relays on a Saturday....or any day. I quit carrying spares 10 years ago.
Luckily there was a "derelict" twin right next to it that I borrowed a couple of parts off of to get this heap back online.
