Regular PTAC maintenance can maximize energy savings and extend the life of your HVAC equipment.
To avoid the risk of property damage, electrical shock, or personal injury, turn off and unplug the PTAC unit before conducting
any routine maintenance or services.
Three Monthly PTAC Cleaning Tasks:
- Air Filter
- Remove the
PTAC air filter slowly to prevent dirt from falling back into the unit. For some units, the front grille must be
removed to access the filter.
- Clean the filter with a vacuum or running water.
- Replace any damaged filters.
- Vent Screen
If the PTAC unit is operated with the vent door closed, the vent screen does not need to be cleaned.
- Remove the front grille.

- Reinstall the front grille.
- Inspect the
control panel door and plug. Replace both if needed.
Three Yearly PTAC Maintenance Tasks:
- Wall Sleeve
- Check the
caulking around the PTAC wall sleeve to make sure all air and water openings are properly sealed.
- Check the wall sleeve's level. It should be tilted to the outside (1/4 bubble tilt) from right to left; if the unit
has an internal drain system, the sleeve should be leveled so that condensate water drains into connected drain line/kit
location. This can be tested by pouring a cup of water into the wall sleeve.
- Check the drain hole locations at rear of sleeve and bottom of sleeve; remove any blockage.
- Base Pan and Condenser Coil
Cover the entire control panel area and fan motor with plastic to prevent damage while cleaning is in progress.
- Clearance Check
- Check clearance around the HVAC unit to ensure that the intake air and discharge air paths are not blocked or restricted.
Leave a minimum of eight inches from the unit to furniture, beds, or other objects for proper operation.
