10 year old AC

Jul 01, 2004 4 Replies

My window unit quit one day. The next day it worked again. That night the motor started squeaking and the next morning the switch was still on but the motor wouldn't run.



I have already bought a replacement ac unit but I was wondering if the old one would be good for anything?



I am guessing that it would cost as much to repair as the new one cost.


Do you have a boat?

I'm *sure* you're correct. I had someone look at my thru-the-wall unit ten years ago, and declared the compressor shot (it would freeze up and kick the breaker). He wanted about $500 to replace the compressor, while a new unit was about $700. Repairing such things *rarely* makes economic sense.

...of course ten years later the unit is still working. I just don't let the fan cycle, so it clears any condensation from the coils.

Sounds like possibly a low refrigerant charge is making things worse.

Quite likely. However, it's going to run until it drops. Given it's age (17-18 years; the age of the house) it will have R12 refrigerant and thus it's not worth fixing. Every year it continues to run it is *saving* me money.

A newer Energy Star unit is going to have a lower cost of ownership. A new window A/C is going to be more energy efficient than a decade old unit.
