Understand the Common Air Conditioning Issues

Improper operation

When the AC is on, make sure that all the windows and doors are closed. Isolate the room from other rooms of your home to enjoy perfect cooling.

Faulty installation

Improper central AC installation can cause the ducts to leak, which can decrease airflow.

Faulty wiring

Uncertified or chaotic AC wiring is hazardous and can possibly cause fire. Fortunately, bad wiring can trip down the circuit breaker and prevent the unit from getting powered.

Refrigerant issues

Refrigerant is responsible to cool the air inside the AC system.

Refrigerant issues

  • Low level

Reduced refrigerant level means there is a leak, which needs to be found and repaired, before recharging.

  • Not as per manufacturers specification

The refrigerant charge performed, during installation doesn’t match manufacturers specification, which impairs the efficiency and performance of the unit.

  • Unqualified service technician

They often fail to locate refrigerant charging issue. In addition, worsen the existing issue by filling in refrigerant to an already full system.

External fan stops working

External fan exhausts the heat from inside the house and throws it outside. If this fan does not perform well then the interiors do not get cooled properly. In addition, the compressor gets overheated and trip due to overload for safety. It can even cause internal compressor damage, which is expensive.

Compressor does not function

If the external unit does not respond, it means lack of power or contact issues or faulty thermostat.

Compressor does not function

Frozen coil

It indicates that there is an airflow issue like filthy air filter hindrances or obstruction due to return air ductwork. Low level of refrigerant can also cause frozen indoor coils.

Inadequate maintenance

In case, the AC coils and filters become dirty then the unit will not perform properly. Fans or compressor can possibly fail, ahead of time.

Failure of electric control

The fan and compressor control wears out, if the AC switches on and off frequently. This happens, when the system is oversized. In many systems wire and terminal corrosion is an issue. Therefore, during professional service have the electric contacts and connections checked.

Sensor issues

A thermostat sensor is fixed at the rear side of control panel. It measures the air temperature that enters the evaporative coil. The position of the sensor is near the coil and not touching it. If it gets knocked out from its position then the AC will start behaving erratically.

Drainage issues

When the outdoor atmosphere is humid then checks the condensate drain for clogs or else the drains will not work properly.

Low refrigerant, air flow issues, and bad wiring can be detected during regular maintenance tune-ups. However, for participating in preventive maintenance program visit http://georgiamechanical.com/
