6 Common Causes of Commercial AC Breakdowns

Maintaining a comfortable indoor environment is crucial for any business. A breakdown during peak operation can not only disrupt business operations but also significantly impact customer and employee comfort. Understanding the common causes of commercial AC breakdowns is the first step toward preventing them. This blog post delves into the various factors that lead to AC failures, providing valuable insights for business owners.

1. Failure to Perform Regular Maintenance

One of the most overlooked aspects of AC maintenance is the regular servicing of the system. An AC unit, much like any mechanical system, requires attention and periodic checks to function optimally. In busy cities where environmental factors such as dust and urban pollution can affect the system, neglecting maintenance tasks such as filter replacement or system checks can lead to reduced airflow, an overworked unit, and eventual breakdown.

2. Refrigerant Leaks 

The refrigerant is the backbone of any AC system, facilitating the transfer of heat from inside to outside. A leak in the system not only reduces the cooling efficiency but can also cause significant damage to the compressor—one of the most critical and expensive components of the system. Early signs of a refrigerant leak include a noticeable decrease in cooling performance and the presence of hissing sounds. Timely detection and repair of leaks are vital to maintaining optimal cooling performance.

3. Electrical Failures and Wiring Issues 

Electrical problems are a leading cause of commercial AC breakdowns. Faulty wiring, corroded contacts, or tripped circuit breakers can halt the operation of an AC unit. In a commercial setting, where systems are larger and more complex, these issues can quickly escalate, leading to system failure. Regular inspections by qualified technicians can prevent electrical failures, ensuring the smooth operation of the unit.

4. Dirty Coils

Both the condenser and evaporator coils play crucial roles in the heat exchange process within the AC system. Over time, these coils can accumulate dirt and debris, which insulate the coils and hinder their ability to transfer heat. In a city environment, pollutants and particulate matter can exacerbate this issue. Cleaning these coils regularly can significantly improve the efficiency and longevity of the air conditioning system.

5. Frozen Evaporator Coils

Another common issue leading to commercial AC breakdowns is the freezing of evaporator coils. Factors contributing to this include low refrigerant levels and obstructed airflow from dirty filters or blocked vents. Ensuring adequate airflow and regular maintenance can prevent the occurrence of frozen coils, ensuring the system’s efficiency.

6. Compressor Failures

The compressor acts as the heart of the AC system, circulating refrigerant and maintaining the cycle of heat exchange. Issues with the compressor, from electrical faults to mechanical failures, can result in a total system shutdown. Regular maintenance and prompt repairs are essential in preventing compressor-related failures.
