Hiring Professional Services for Air Conditioner Maintenance

When your air conditioner needs more than the regular maintenance described previously, hire a professional service technician. A well-trained technician will find and fix problems in your air conditioning system. However, not all service technicians are competent. Incompetent service technicians forsake proper diagnosis and perform only minimal stop-gap measures. Insist that the technician do the following:

• Check for correct amount of refrigerant

• Test for refrigerant leaks using a leak detector

• Capture any refrigerant that must be evacuated from the system, instead of illegally releasing it to the atmosphere

• Check for and seal duct leakage in central systems

• Measure air flow through the evaporator coil

• Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously

• Inspect electric terminals, clean and tighten connections, and apply a non-conductive coating if necessary

• Oil motors and check belts for tightness and wear

• Check the accuracy of the thermostat.
