PTAC or Packaged Terminal Air Conditioner units are commonly used in commercial buildings. They offer an efficient solution for heating and cooling spaces without the need for a central HVAC system. However, just like any other mechanical device, regular maintenance of PTAC units is critical to ensure they operate at peak efficiency and prolong their lifespan. In this blog, we will share eight maintenance tips for your PTAC unit to keep it running smoothly and efficiently.

Clean or Replace Air Filters
Dirty or clogged air filters restrict airflow and reduce your PTAC unit’s efficiency. You should clean or replace the air filters every 30 days or based on the manufacturer’s recommendation. If you operate a commercial building, consider investing in a maintenance contract with a reputable contractor.
Clean the Coil
The PTAC unit’s coil works to absorb heat from the room and expel it outside. The coil, however, collects dust, debris, and other particles over time, which can hinder performance. You can clean the coil by vacuuming, brushing, or using a coil cleaner that’s available in the market.
Check the Thermostat
Ensure that your PTAC unit’s thermostat is working correctly. If you notice that your unit is frequently on and off, or it’s blowing warm air instead of cold air, it could indicate a malfunctioning thermostat. You should replace the thermostat or call a professional technician to have a look.
Inspect for Refrigerant Leakage
Refrigerant leakage can cause your PTAC unit to operate inefficiently or stop working completely. If you see signs of refrigerant leakage, such as icing on the evaporator coil or hissing sounds near the unit, call a professional immediately.
Lubricate Fan Motor
Have your PTAC unit’s fan motor lubricated annually to keep it running smoothly and reduce wear and tear. You should consult the manufacturer’s guidelines for recommended lubrication intervals.
Tighten Electrical Connections
Over time, electrical connections in PTAC units can loosen, which can cause the unit to invalidate the warranty, damage the unit, or even cause a safety risk. Ensure that all electrical connections are tight and secure by periodically checking and tightening them.
Clean External Components
Clean the exterior components of your PTAC unit such as the grille, cabinet, and fins using mild soap and water. The cleaner the exterior components, the better the unit’s overall performance.
Regular Maintenance
Arrange for professional maintenance services for your PTAC unit at least once a year, depending on usage and manufacturer recommendations. Professional maintenance includes checking refrigerant levels, cleaning and tightening electrical connections, inspecting the thermostat and motor, and checking belts and bearings.
Conclusion
In conclusion, regular maintenance of your PTAC unit ensures it operates efficiently, conserves energy, and reduces your energy bills. With these eight PTAC maintenance tips, you can take care of your unit so that it consistently provides quality heating and cooling services to your commercial building. Maintenance also prolongs the unit’s lifespan, ensuring that you get the most value for your investment. If you require professional maintenance services, don’t hesitate to call certified and reputable HVAC contractors to ensure that you get quality services and peace of mind.
