Packaged System Preventative Maintenance

Packaged systems, also known as all-in-one systems are becoming increasingly popular in regions where construction techniques favor a single cabinet design over split systems comprised of both an outdoor and indoor unit.

While packaged systems are typically installed outdoors at ground level, technicians may also install an all-in-one unit in a crawl space or even on the roof for horizontal or down-flow designs. This can make performing preventative maintenance difficult, and in which case should always be performed by a Trane Comfort Specialist.

Packaged System Preventative Maintenance Tips

While most packaged system preventative maintenance should be performed by a certified dealer, there are a few basic maintenance tasks you can perform without the help of a certified technician – assuming of course your unit is installed at ground level.

  • Clean or change your filters once a month or as needed.
  • Maintain the system according to your Trane manual.
  • Clean outdoor coils whenever they appear dirty.
  • Remove foliage and clutter from around the outdoor unit.
  • Clean the supply and return registers in your home and straighten their fins if bent.

Packaged System Preventative Maintenance Checklist

You should have a Trane Comfort Specialist examine your packaged system at least once a year. A certified comfort specialist will follow a packaged system preventative maintenance checklist to insure the health of your unit. Your Trane technician will inspect the following:

  • Ducts, filters, blower, and outdoor coil for dirt and other obstructions.
  • Duct leakage.
  • Adequate airflow.
  • Correct refrigerant charge.
  • Refrigerant leaks.
  • Electric terminals, and, if necessary, clean and tighten connections, and apply nonconductive coating.
  • Lubricate motors, and inspect belts for tightness and wear.
  • Correct electric control, making sure that heating is locked out when the thermostat calls for cooling and vice versa.
  • Correct thermostat operation.
