What are the common causes of air conditioner failure?

If you reside in Georgia, the summers can be quite intense. Working or living in a place without adequate air conditioning is far from ideal. Due to increased usage, AC systems go through wear and tear, especially if they are older than 10 years old. It is necessary to have your air conditioner inspected, maintained or repaired to prevent issues from arising.

Common Causes of Air Conditioner Failure

Below Are Some Common Causes of Air Conditioner Failure.


  • Low Refrigerator

Refrigerant helps remove the heat and humidity from the air in your house or place of business. You might need to add more refrigerant to adequately cool the air if your system develops leaks in the refrigerant lines.

Finding the leaks and fixing the holes in the lines involves the assistance of our HVAC repair specialist, which can occasionally but your air conditioner will work properly.

  • Evaporator Coils are Frozen

Packed with refrigerant, the evaporator coil in your air conditioner is in charge of soaking up heat from the air like a sponge. Although it may seem counterintuitive, these coils need warm air to move around and function effectively.

A thin layer of ice can be collected outside if the airflow is disrupted and the evaporator coil becomes too cold. When that occurs, the air flowing from your air conditioning supply registers will be heated or won’t come.

  • Unclean Condenser Coils

Condenser coils in your unit’s exterior unit exhaust the heat that has been taken from the air outside the structure. The condenser coil won’t function properly when coated in dirt and filth. When heat transfer is inhibited, your unit must work harder to do its task, which increases part wear and may result in system failure.

  • Fan Issues

Air is blown over your unit’s evaporator coil to chill the air in the room, and the atmosphere is blown over the outdoor unit’s condenser to expel heat into the outside air. If any of those fans aren’t functioning properly, you have inadequate airflow and issues with your air conditioner.

Fan issues can be caused by a defective motor, a lack of oil, worn belts, or too much dirt and debris. If you ignore the issue, compressor failure could result, which is frequently the end of your air conditioner.

  • Leaky Ducts

The cooled air from the air conditioner disturbs your area through the ductwork that runs through your walls and ceilings. However, that pricey chilled air can end up inside your walls, where it is useless if there are holes or cracks in the ducts (which can be caused by mice or negligent workers). Of course, your air conditioner has to work harder in this situation, which increases your energy costs.

  • Problems with Thermostat

Your old thermostats, especially, may need to be calibrated appropriately, which can help prevent your air conditioner from receiving the proper commands from the control system. Your thermostats can be easily replaced or recalibrated to solve this issue.

It can be challenging to program new programmable thermostats, which might be set incorrectly. If you still have one, verify the directions in your thermostat’s manual to ensure the settings are proper.

  • Drainage

Your air conditioner disposes of all the moisture it takes from the air. It is intended to be eliminated from the area via a drain line, a pan, and a drain. The water might come back and harm your system if the line, drain, or pan becomes full. In addition, you can experience water leaks that harm your furnishings, ceilings, and walls. It will gradually spread if you overlook mold development.
