Air Conditioning Myth #1

Air Conditioning Myth #1
All the technician has to do is stick his gauges on the unit to tell if it is low on refrigerant.

There is no gauge that measures the level of refrigerant (Freon) in a unit. The gauge set that a technician uses is only one of several tools used in a procedure that if followed correctly will let a technician know if a system is low or over charged.

• Refrigerant gauges measure the refrigerant pressure inside the air conditioning unit. That pressure fluctuates with temperature changes inside and outside of the home as air is circulated thru the indoor coil and the outdoor coil.

• The amount of air flowing thru the coils will dramatically change the temperature and pressure of the refrigerant. A coil that is only slightly dirty may reduce air flow by 10% to 20% and change the pressures significantly. Other issues that may cause temperature/pressure changes are; dirty filters, dirty blower wheels, weak motors, duct restrictions, etc…

• Therefore it is critical that a technician check and correct airflow problems BEFORE adjusting refrigerant levels. Poor airflow can lead a technician to overcharging a unit. This will cause serious damage to an air conditioning unit and may not be detected for several months or even years.

• When a technician does not follow the correct procedure he is guessing. This means you are paying someone to damage your unit. Studies have found more than 70% of systems are being installed with the wrong amount of refrigerant. This is due to little to no training of the installers and technicians in the field.

At B&J we know our success depends on having great technicians in the field. We are very selective in our hiring process. We believe we must hire great people and make them better. We train our people to follow the correct procedures and communicate well with our customers. We don’t guess. Give us a try; you will be glad you did.
