Common Causes of Air Conditioning Repair

Although there are potentially hundreds of reasons for air conditioning repair, there are a few reasons that are quite common. The real and number one reason for some homes is the improper operation of the machine.

Common problems with existing air conditioners result from faulty installation, poor service procedures, and inadequate maintenance. Knowledge on what air conditioning is and how air conditioning works may help you understand what a technician is referring to when you need to discuss the options for the correcting a problem. Improper installation of an air conditioning system can result in leaky ducts and low airflow. Many times, the refrigerant charge does not match the manufacturer’s specifications. If proper refrigerant charging is not performed during installation, the performance and efficiency of the unit is impaired. Let’s take problems one by one.

  • Low refrigerant. Refrigerant is the chemical that cools the air. Low refrigerant may indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that means there is a leak. Remember that the performance and efficiency of your air conditioner is greatest when it has ample refrigerant. That is why in air conditioning repair, knowing when the refrigerant charge exactly matches the manufacturer’s specification, and is neither undercharged nor overcharged.
  • Frozen coil. A frozen coil indicates a problem with the airflow, such as restrictions caused by dirty air filters or blocked return air ductwork. When it’s humid outside, check the condensate drain to make sure it isn’t clogged and is draining properly. Room air conditioners may not drain properly if not mounted level.
  • Electric control failure. Air conditioning repair is common for this case when the compressor and fan controls can wear out, especially when the air conditioner turns on and off frequently. This commonly happens when a system is oversized. Due to the corrosion of wire and terminals, electrical and contacts can be a problem and may need to be checked and repaired. Another problem related to this is the outside fan. The outside fan is responsible for transferring the heat from your home to the outside air. If the fan on the outside unit doesn’t run, proper heat transfer is not taking place and the air conditioning compressor may overheat and trip the safety overload. When the compressor gets damaged, then expensive air conditioning repair is expected.

Air conditioning repairs can be lessened or avoided when you are knowledgeable of your air conditioning parts and that of the sensitive areas. To know more about air conditioning repair, call our professionals at Brown Heating, Cooling and Plumbing today.
