Air conditioning systems are essential for comfort during the hot months, but like any mechanical system, they’re prone to certain issues. Being able to recognize the common problems and their symptoms can help homeowners address issues quickly, potentially avoiding costly repairs. Absolute P&M Services would like to share some of the most common problems that plague air conditioners and what might be going wrong and how to identify the signs.

Refrigerant Leaks

The refrigerant is the lifeblood of your air conditioning system, essential for cooling your home. If your system is low on refrigerant, either from a leak or because it was undercharged at installation, your system will not perform effectively. Some of the common signs of a refrigerant leak are:
• Poor cooling
• Hissing noises from the air conditioner units
• Ice buildup on the refrigerant lines
• Increasing energy bills

Dirty or Clogged Air Filters

One of the simplest air conditioner problems to fix is a dirty or clogged air filter. However, if left unattended, it can lead to more serious issues. Airflow restrictions can strain your system, decrease efficiency, and worsen indoor air quality. Signs of clogged or dirty filter are:
• Reduced airflow through vents
• Ice on the evaporator coils inside the unit
• The system struggles to cool or cycles frequently
• Increased dust levels in your home

AC Drainage Issues

The condensate drain can become clogged with algae, dirt, or debris, causing water to back up and potentially cause damage to your system or your home. Some of the common signs of drainage problems are:
• Water leaks around the indoor unit
• Musty smells or high humidity levels inside
• Water damage near the air handler

Faulty AC Compressor

The compressor is responsible for moving the refrigerant between the evaporator and condenser coils, cooling your home. If the compressor is malfunctioning, the entire system will fail to cool your space. Signs of a faulty or failing compressor may be:
• Air Conditioner not cooling
• Compressor not starting or making noises
• System trips the circuit breaker
• Hot air being expelled from the outdoor unit

Frozen Evaporator Coils

Evaporator coils need warm air circulating around them to operate correctly. When something goes wrong with the airflow and the coils get too cold, a layer of ice can build up on the outside. Signs of frozen evaporator coils can include:
• Ice buildup on the outside of the indoor unit
• Humming sound from the frozen coil
• Minimal air coming out of your air conditioner vents

Worn Out AC Fan Motors

The fan motors are essential for the proper movement of air through your system. If they are faulty, it can lead to poor airflow and overheating, which could damage the compressor. Signs of a worn fan motor are:
• Air conditioner runs but little to no air comes out of the vents
• Overheating air conditioner unit
• Loud, rattling noises from the unit when the fan is running
