Thats about it unless you want to pay a refrigeration service co. to recover the refrigerant, remove the condenser, clean the condenser, braze the condenser back in, evacuate the system, replace the dryer, recharge the system, and give you a big invoice. If you notice that commercial fridges have a complete condensing unit on top so it can be easily worked on without even moving the unit.

According to "what seemed to me" a "Knowledgeable former poster here, He claimed that some of the "Copper Problems" that SZ had with "Evaporators, not Condensers, as I recall, was due to the use of 2 metals, copper tubing with aluminum fins and yes moisture, particularly the kind near the sea shore, exacerbated the oxidation of the copper coils, but as I mentioned, as far as I had read, that was the evaporator coils not the condenser coils--- BUT-- as the other poster here said, "Check with SZ", better safe than sorry! Good luck with it! Gary

sorry for the bad typing - I was asking if the Honeywell F100 was the one you were recommending in your previous post to me. I currently have a central return with two 20 x 25 filters in my hallway (no whole house filter in the attic). My house is 3000 sq ft; I'm not experiencing any problems, so I probably won't get the ducts cleaned. I will check into the new refrigerant lines though, since I am going to a new refrigerant.

You mean the indoor coil? If AC only, that would be the evaporator coil. Condenser is outside. If indoor, why is this not enclosed with a suitable filter arrangement? Installing without filter is unconscionable.
