Air Conditioner Issues

Refrigerant Leaks

If the central air conditioner is activated and your household feels hot or humid, this is a an indicator of a problem with the refrigerant lines. Once the refrigerant supply becomes too low, the air conditioning system will be unable to extract heat from the air. Although a leak is able to be easily fixed by refilling the refrigerant, this is only a temporary fix. The only way to fix a refrigerant leak is to hire a licensed plumber to find and fix the crack in your refrigerant lines. 

To ensure you are able to detect issues with your air conditioning system, it’s important to be familiar with ordinary signs of a refrigerant leak. If you have a crack or hole in your refrigerant lines, you may notice condensation or ice on your evaporator coils. Once the amount of refrigerant in the evaporator coils becomes too low, the coils will not be able to effectively extract heat energy from the air in your home. This air conditioner problem may cause the evaporator coils to become frozen.

6 Ordinary Air Conditioner Problems & How to FixWater Leaks

Your central air conditioner is engineered to remove heat and moisture from the air in your house. Once the moisture is collected by your system, it is flushed through a drain pipe to prevent mold growth and water damage in your household. If you notice wet flooring or walls in your home, this is a sign of a blockage in your condensation drain. To fix this type of air conditioner problem, attach a wet or dry vacuum to the end of the drain pipe. This will help loosen and eliminate the blockage in your central air conditioner.

Tips & Insights: Why Is My Central Air Conditioning System Leaking Water?

Faulty Wiring

Central air conditioning systems are designed to operate in 15 to 20 minute cycles three times per hour. If your air conditioner is deactivating too quickly, this is an indicator of a tripped circuit breaker. To fix this air conditioner problem, navigate to the electrical panel in your household. Next, flip the switch to the off position and then to the on position. Although it may be normal for the circuit breaker to trip a couple of times throughout the summer months, this issue should not happen on a monthly basis.

If your circuit breaker shuts down once or twice a month, this issue may be caused by faulty wiring or malfunctioning electrical components. For example, an electrical short will cause your breaker to deactivate when your central air conditioner is turned on. To prevent damage to your compressor or a house fire, we recommend calling a certified plumber to fix the wiring in your air conditioning system.

Broken Capacitors

Are you unable to activate the fan in your central air conditioner? An ordinary cause of this problem is broken capacitors. The capacitors in an air conditioning system are engineered to provide the electricity necessary to activate the motor. If you notice a clicking noise at the beginning of the cooling cycle, this is a signal of a malfunctioning capacitor. To avoid costly motor problems, we recommend hiring a plumber to replace or repair the capacitors on your air conditioning system.

6 Ordinary Air Conditioner Problems & How to FixDamaged Compressor

The compressor in a central air conditioner is designed to distribute the refrigerant to the condenser and evaporator coils. In addition, this component is required to regulate the pressure in your air conditioning system. As your air conditioner reaches the middle of its life cycle, Issues such as refrigerant leaks, contaminated evaporator coils, and faulty capacitors can easily cause damage to the compressor. If your air conditioner is distributing warm air in your house, this is a sign of a damaged compressor. To fix this problem, you will need specialized tools, equipment, and training. To avoid injury or damage, you should consider hiring a licensed technician to repair or replace your compressor.
