Zoneline Air Conditioners - Cleaning Indoor Coil
To properly clean & maintain the indoor coil on a GE Zoneline packaged terminal air conditioner or heat pump:
- Always disconnect power before cleaning.
- Indoor coils do not normally require frequent cleaning unless filters are not regularly cleaned.
- Indoor coils should be checked every 6 months for build-up of lint/debris, etc. If there is a build-up of lint/debris on the coil, it should be vacuumed using a soft bristle attachment.
- If the build-up cannot be removed with a vacuum, a mild coil cleaner or household cleaner may be used to remove it. Simple Green or oxygenated cleaners are acceptable choices. Avoid Hydroxide or Acid based cleaners. The PTAC should be taken to an area where water spray will not cause a problem. The cleaner may be sprayed on the coil and allowed to set for a few minutes and rinsed off with a low-pressure water hose. High-pressure spray equipment or steam cleaners should not be used because they are difficult to control and may damage electrical components, aluminum fins, and gasket materials. Controls should be covered to prevent water damage. Allow unit to dry thoroughly before reinstalling.
