Clean and check condenser coil:

Dirty condenser coils raise refrigerant pressure higher than needed, increasing your electric bill.

Check operating pressures:

This ensures your equipment is running at peak efficiency.

Check starting capabilities:

This is to ensure your motors and compressor is operating correctly.

Check safety controls:  

This ensures the motors and compressors are starting properly to prevent costly repairs.

Check, clean or replace filters (if needed):  

A clogged filter causes the air conditioning unit to run continuously and very poor air flow which may cause the coil to freeze, shortening the unit's life.

Check and adjust blower components:

Dirty blower wheels reduce airflow, causing increased operating time and increased cost. Inadequate airflow is another major cause of compressor failure.

Visually check for correct airflow:

This ensures ducts are properly sealed.

Check condensate drain:

A clogged drain caused by algae can cause water damage and unpleasant smells.

Check all electrical connections:

This ensures no terminals are loose, which can cause excessive heat.

Lubricate all moving parts where necessary:

This will keep bearings from wearing out.

Check thermostat calibration:

This is to ensure the system is cycling on and off properly.

Check for proper temperature difference:  

This is necessary to ensure the whole system is operating effectively.

 Check Amperage:  

This is necessary to ensure the equipment is drawing proper current.
