How old? If it was me, anything close to 15 years old (when it requires major repair) and I replace it, 8 years old, repair, in between sliding scale (i.e. I am not paying for a new compressor on a 12 year old unit.)
I've had the house for 10 years, not how long it was dead before then and not sure when it was installed. besides the condensor coils bursting I don't know if there's anything else wrong with it, i suspect with the amount of sitting it's done it's scrap metal
there only a week per year where i think it would be nice to have.
That's why I will never get central air. Down here it's more than a week, but still.
Also walking out of an airconditioned house and adjusting your life around a/c is bull. Heating? Ya, I'm all over heat in winter.
