Dealing with Commercial AC System Issues: A Practical Guide

Regular AC maintenance can help mitigate these issues before they become serious problems.

A commercial air conditioning unit proves its worth in the summer by keeping your facility cool and your employees, customers, or tenants happy. Regular maintenance is necessary for your commercial air conditioning unit to avoid breakdowns. If you’re experiencing issues with your HVAC unit, one of the following problems could be the cause.

Common Commercial AC Issues

Due to their size and complexity, commercial air conditioning systems can experience various issues. Here are some common problems:

  • Inadequate Cooling: The most common issue is that the system doesn’t cool as efficiently as it should. This could be due to various reasons, such as a refrigerant leak, dirty filters, or issues with the thermostat.
  • Refrigerant Leaks: If the refrigerant levels in your system are low, it’s usually due to a leak, as the refrigerant isn’t something that gets “used up.” Leaks not only reduce the efficiency of your system, but they’re also bad for the environment.
  • Poor Airflow: This can be due to dirty or clogged filters, obstructions in the ductwork, or a failing fan. Poor airflow means the system can’t effectively distribute cool air, leading to uneven cooling.
  • Sensor Issues: Commercial AC systems have thermostats and sensors to measure the air temperature. If these fail or start giving inaccurate readings, it can cause the system to cycle irregularly or not maintain the correct temperature.
  • Drainage Problems: Just like in a residential unit, the condensation your commercial AC creates needs to be drained out. If the drain becomes clogged, it can lead to water damage in the unit or the surrounding building structure.
  • Electric Control Failure: The compressor and fan controls can wear out, especially when the AC turns on and off frequently. Electrical connections and contacts can also become corroded over time, leading to poor operation.
  • Thermostat Issues: If the thermostat is not calibrated correctly, it can cause the system to cool unevenly or not turn on when needed.
  • Belt and Bearing Wear and Tear: Over time, the belts and bearings in the system can wear out, leading to decreased efficiency and potential system damage if not addressed quickly.

When it comes to managing a commercial building, maintaining an optimal indoor environment is crucial. At the heart of this is the air conditioning system, which maintains comfortable temperatures and plays a significant role in indoor air quality.
