Common Air Conditioner Problems

Common Air Conditioner Problems
2
Refrigerant leak

•  Refrigerant leaks can happen with vibration of
  the unit while it is operating.
• If the leak is found the technician can remove
  what is left and charge the unit levels back to
  their correct amount

3
Thermostat

•  If the thermostat requires calibration, contact
  a service professional.
• Before calling an HVAC company, make sure the
  thermostat is on.  Many times the thermostat is
  accidentally turned off or is on the wrong
  setting.

4
Compressor

• If the unit is undercharged with refrigerant, the
  compressor will run hot and will eventually
  seize. 
• If the unit is overcharged, your liquid
  refrigerant will get back to the compressor and
  cause liquid slugging. 

5
Frozen Units

• Frozen coils are easily recognizable because
  the pipes and unit will usually be frozen solid
  in a block of ice. This causes circulation
  problems.

6
Dirty A/C Units

• One of the most common causes of A/C failure is
  that the grills are blocked.
• Dirty A/C units wont operate at peak efficiency,
  and simple cleaning like this can help restore a
  unit back to like new status.

7
Blown Fuses

•  Fuses protect the unit's motor or compressor
  against overheating, and is found in the
  evaporator coil.
• When a motor is suspected of going bad, the
  breaker is one of the first things the technician
  checks.

8
Dirty Filters

• One possible reason that HVAC systems blow
  warm air is dirty filters.
• The system is producing cold air but it cannot
  flow through the ductwork. Clean air filters
  protect your equipment and help it perform
  properly. 

9
Fan Belt

• Occasionally, air conditioners will start to make
  loud (sometimes deafening) banging or wailing
  noises. If this happens, most of the time it is
  the result of a dislodged fan belt.
• This fix is not difficult, but because this is
  high powered electrical equipment, you will need
  a licensed professional to fix it. You should not
  switch on the air conditioner until its been
  fixed doing so could cause far more damage.
