the HVAC tech checked it today and said the compressor is dead.

here's what's happened in the last week...

The outside unit has been making loud noises and vibrates when in defrost mode for about two months or so...

I called a service repair company that I have never used before but is on the HVAC manufactures list of recommended service companies...

the unit was checked last Friday and the tech stated the unit was significantly over charged... some Freon was removed...

the unit seemed Okay until Sunday (but now my son says our lights dimmed more than usual on Saturady)... on Sunday morning I noticed the lights were dimming about every ten minutes...

I called the service company to come back out today (Monday)
------------------------

it seems very possible the compressor has been so stressed that it finally died... the unit is 14 years old

but, i'd like to take the unit out another 5 years...

Questiom:
are refurbished compressors an option?

are refurbished compressors a big risk?

could the unit just be out of Freon? I don't think the tech today hooked up the meter... but I'm not sure.

if a new unit is the only/best option, I'm considering a Carrier Infinity or Trane similar system... any thoughts or recommendations...

Thanks,
