6 Common Causes of Commercial AC Breakdowns

A functioning commercial air conditioning system isn’t just a luxury; it’s a necessity. However, like any complex mechanical system, commercial AC units can and do break down, often at the most inopportune times. Understanding the common causes of these breakdowns can help local business owners and facility managers prevent them, ensuring their operations remain cool and comfortable, even in the peak of summer. Here’s a closer look at some of the most prevalent reasons behind commercial AC failures.

1. A Lack of Maintenance. One of the primary culprits of commercial AC breakdowns is the lack of regular maintenance. This includes tasks as simple as cleaning and replacing air filters to prevent reduced airflow and overworked systems. In a dusty environment, filters can quickly become clogged, exacerbating the problem. Scheduling annual check-ups with a reputable HVAC company like EZ Air Conditioning Inc. can catch minor issues before they escalate into major, costly repairs.
2. Refrigerant Leaks. Refrigerant is the lifeblood of your AC system, absorbing indoor heat and releasing it outdoors. A leak not only diminishes cooling efficiency but can also cause significant damage to the compressor, an essential and expensive component of your AC system. Signs a possible refrigerant leak is present include frozen coils and hissing sounds.
3. Electrical Failure. Faulty wiring, worn-out capacitors, and tripped circuit breakers are common electrical issues that can cause an AC system to malfunction or shut down entirely. Given the potential for fire hazards, professional inspection of commercial HVAC units is imperative.
4. Dirty or Blocked Coils. Over time, condenser and evaporator coils can accumulate dirt, dust, and debris. In a bustling city where the air carries contaminants from both urban activities and natural sources, this is a frequent issue. Dirty coils hamper efficient heat transfer and lead to decreased system performance and higher energy consumption. Regular coil cleaning is an effective prevention strategy.
5. Frozen Coils. The issue of frozen evaporator coils often ties back to airflow problems, commonly due to dirty air filters or obstructions near the unit. This can be especially problematic in spaces with high foot traffic or those that generate a lot of dust and debris, common in commercial environments. Regularly changing air filters and ensuring clear airflow can mitigate this risk.
6. Compressor Issues. The compressor, often deemed the heart of the AC system, pushes refrigerant through the cooling circuit. Electrical failures, motor problems, or excessive pressure can lead to compressor malfunctions, resulting in warm air or a complete shutdown. Regular maintenance is your best defense against such costly failures.
