Common AC Problems in Summer

Whether you have a central cooling system or a window unit, the air conditioner enables you to sustain a pleasant indoor temperature despite the scorching external heat. But what occurs when your reliable AC unit malfunctions? Discover the typical issues air conditioners encounter in the summer and the solutions to resolve them.

The Refrigerant Charge Is Low

Low refrigerant charge in an air conditioning system occurs when an insufficient amount of refrigerant is present. This situation arises when the level of refrigerant in the system drops below the recommended or required level.

A low refrigerant charge can result from leaks or improper initial installation. The consequence of this condition is a reduced cooling capacity of the AC system, as refrigerant is responsible for absorbing heat from the air. 

Inadequate refrigerant charge leads to decreased efficiency, increased energy consumption, and inadequate cooling performance. The refrigerant levels need to be checked and adjusted to meet the specified guidelines, ensuring optimal AC operation and cooling efficiency.

The Air Filters Are Clogged 

Clogged air filters in an air conditioning (AC) system occur when dust, debris, and other particles accumulate and obstruct the airflow. As the AC unit draws in air, these contaminants gradually amass within the filters. 

This accumulation restricts air passage, hindering the AC's ability to cool the environment efficiently. In turn, the clogged air filters negatively impact the overall performance of the AC system, potentially leading to reduced airflow, increased energy consumption, and diminished cooling capacity. 

Regular maintenance and timely filter replacement are crucial to prevent contaminant buildup and maintain the optimal functioning of the AC unit.

The AC Won't Turn On

A faulty thermostat might be unable to send the necessary signals to the cooling system. Secondly, a tripped circuit breaker or blown fuse could disrupt the power supply. Additionally, a malfunctioning compressor or motor may hinder the AC unit's functionality. Insufficient refrigerant levels might also impede cooling.

Moreover, a clogged air filter can restrict airflow, preventing the AC from operating effectively. Lastly, damaged electrical connections or wiring issues might disrupt the overall functioning of the system.

The Run Capacitor Fails

Excessive voltage stress can cause the dielectric material inside the capacitor to break down, resulting in a loss of capacitance. Additionally, prolonged exposure to high temperatures can lead to the deterioration of the dielectric, reducing the capacitor's effectiveness.

Mechanical stress or vibration can also weaken the internal connections and lead to failure. Furthermore, the accumulation of moisture or contaminants within the capacitor can cause corrosion or short circuits, disrupting its functionality. Finally, electrical surges or overloads can overwhelm the capacitor, causing it to fail.

The Coils Are Dirty

Dirty AC coils in an air conditioning system occur when dust, dirt, and debris accumulate on the coils. These foreign substances hinder the coils' ability to transfer heat efficiently. As a result, the cooling process becomes less effective, leading to decreased performance and increased energy consumption. 

Dirt on the coils can be attributed to various factors, such as improper filtration, poor maintenance, or environmental conditions. Regular cleaning and maintenance are crucial to prevent dirt buildup on the coils and ensure optimal performance of the air conditioning system.

The AC Blows Hot Air

This situation occurs when the air conditioner fails to cool the air as it should. Various factors can contribute to this issue, such as a malfunctioning compressor, refrigerant leak, or clogged air filter. When these problems arise, the AC unit becomes unable to extract heat effectively from the air, resulting in warm air circulating instead.
