Regular Service Maintenance
Cooling and Heating Season
Basic Maintenance – For All Packaged Systems
To keep your unit operating safely and efficiently, a qualified
service technician should check the entire system seasonally,
and any other time that you feel a check is needed. Your service
technician may examine these areas of the unit:
1. Filters(forpossiblecleaning)
2. Motors(condenserandevaporatormotorsare
permanentlylubricated)
3. Gaskets(forpossiblereplacement)
4. Refrigerantcoils(forpossiblecleaning)
5. Safetycontrols(formechanicalcleaning)
6. Electricalcomponentsandwiring(forpossible
replacementandconnectiontightness)
7. Condensatedrain(forpossiblecleaning)
8. Inspecttheunitductconnectionstoseethattheyare

Heating Season Additional Maintenance – For
Gas/Electric and Dual Fuel Packaged Systems
At the beginning of each heating season arrange for a qualified
service technician to complete the unit inspections and service
routines described in this section.
These steps should be performed ONLY by a qualified service
technician.
1. Inspectthecontrolpanelwiringandheatingcontrolstomake

IMPORTANT: Some of these products have been designed
and manufactured to meet ENERGY STAR criteria for energy
efficiency. However, proper refrigerant charge and proper
air flow are critical to achieve rated capacity and efficiency.
Installation of this product should follow the manufacturer’s
refrigerant charging and air flow instructions. Failure to confirm
proper charge and airflow may reduce energy efficiency and
shorten equipment life.
