Maintenance is important for PTAC units, the better they are maintained the less likely they are to break down or need new parts. See below for more information.

• Join our Maitenance protection plan
  
• Receive yearly check ups
• Any repairs needed after the initial warranty is 20% off

• Filters should be checked weekly and cleaned monthly. Cleaning may be required more often if new carpet has been installed or the property is new.
• Dirty filters may decrease operating efficiency by as much as 20%. When filters are clogged air will try to bypass the filters at every opening. This lint/debris will attach itself to the indoor coil and restrict airflow. If this material becomes hard, it becomes difficult to remove and professional cleaning may be required.
• A good procedure is to have an extra supply of replacement filters and use them to replace the dirty filters on a routine basis. The dirty filters could be cleaned and used for the next scheduled change out depending on your brand. If 25% of the rooms were done weekly, the entire facility could be completed monthly.

• Always disconnect power before removing Room Front.
• About every 6 months, the Room Cabinet should be removed and all loose lint/debris on the inside should be vacuumed off. This includes the Control Box area. A soft bristled attachment brush or crevice tool can be used to remove all loose material. This will reduce the chance this material could get on the indoor coils.
• The exterior of the Room Cabinet should be cleaned with mild soap and water. Chemical cleaners should not be used because they may cause the plastic material to become brittle and easily broken.

• 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.

• Always disconnect power before cleaning.
• Outdoor coils should be checked regularly for build-up of dirt/debris. The dirt/debris will be on the inside of the coil because of the airflow direction. If the Zoneline is exposed to construction sites, flowering trees/shrubs, or other local pollutants, the units should be checked and cleaned more frequently to avoid premature compressor failure. Sealed system warranty could be affected if outdoor coils are blocked due to dirt/debris. Lower floors tend to get dirty more quickly than upper floors and should be monitored accordingly.
• Outdoor coils may be cleaned with a mild coil cleaner or materials such as oxygenated cleaners or Simple Green. Avoid Hydroxide or Acid based cleaners. Since the debris may be hard due to the elevated coil temperatures and constant airflow, it may take more than one application to soften and remove the dirt.
• 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. Repeat as necessary. 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.
