I'm doing a through the wall AC installation with an older Admiral unit. My question is regarding the condensate drainage. This has a heavy steel tray, and I've looked in vain for a drain hole. There was almost an inch of wet guck in the tray when I got it. Are some AC's set up to just let the condensation drip into and evaporate in the tray?
Yes, actually. It is more efficient, the water splashes on the condenser coils to aid in cooling them. The A/C unit I bought last year said that if the noise is bothersome (it isn't) I could drill a hole in the bottom to let the water drain out.
