Here is a checklist of services performed during general
service calls:

• clean or replace filters
• clean blower assembly
• oil motors
• clean burners
• clean heat exchanger & inspect for cracks
• clean pilot & flame sensor assemblies
• check fan-limit safety operation
• sequence thermostat, check anticipator, & make sure stat is level
• check compressor, electric elements, & all motors for proper amp draw
• check all power supplies for proper voltage
• inspect for loose, burnt, or broken wires & connections
• inspect all flue pipes & connectors
• inspect all gas piping & connections
• inspect & clean dirty refrigerant coils
• check refrigerant levels
• clean miscellaneous debris from equipment
• check compressor windings
• check all belts & pulleys
• check all condensate drains & pumps
• clean outside cabinets of equipment
• check all accessories (e.g., humidifier, air cleaners, zone controls, & dampers)

Dirty coils & blowers, or units low on refrigerant will not operate efficiently & will deliver less air.

Clean equipment operates more efficiently & with fewer break downs, while offering you lower utility bills & delivering cleaner, healthier air.
