I was sitting on my couch yesterday watching a little Columbo when all of the sudden plumes of the most foul smelling smoke started pouring into the apartment from my AC. (Not unlike the smoke monster from Lost) I unplugged it, taped a plastic bag over the cover to prevent more foul air from coming in the living room and am now trying to decide what to do.
The unit is a Friedrich RS16 QuietMaster Deluxe, 230v 16300BTU wall mounted air conditioner. They don't make this model anymore so I'm wondering if it's even worth getting repaired. New comparable models of Friedrich's are around $1,100!
This is my main question: Do I have to replace the old unit with one of the exact same dimensions?
I live in a co-op with brick exterior walls. The appliance salesman seemed to think my best bet was going with a slightly larger unit, Friedrich CP18F30 ($550) and paying them $300 to deliver the new unit, widen the hole and provide a lentil to support the brick, and remove the old unit.
Does this sound like the way to go or is a salesman trying to do what salesman do? Do people generally replace large, more inefficient units with smaller ones? How do you fill the hole?
If anyone has some insight I'd love for you to share it!
