How Often Should My Commercial AC Be Serviced?

To maintain a comfortable facility and keep overhead predictable, we recommend a professional service at least twice per year, typically once in the spring before the cooling season begins and once in the fall. However, for high-demand commercial facilities where systems run 24/7 or are exposed to heavy dust and debris, quarterly maintenance is the industry standard for peak performance. Regular servicing is the only way to catch minor wear before it turns into a midnight emergency.

Even with a solid service schedule, commercial systems can experience unexpected stress. Keeping an eye out for these early warning signs can be the difference between a simple part replacement and a total system failure.

Here are some key signs that your AC needs professional attention:

• Sudden spikes in utility costs - If your energy bills are climbing without a change in usage or rates, your system is likely working harder than it should to maintain temperatures.
• Unusual noises or vibrations - Grinding, squealing, or persistent rattling often indicate a failing belt, a motor issue, or loose internal components that require immediate calibration.
• Short cycling - If your unit is turning on and off rapidly throughout the hour, it may be struggling with a faulty sensor, an oversized unit, or a failing compressor.
• Inconsistent temperatures - When certain zones in your facility stay warm while others are freezing, it points to a potential ductwork leak or a malfunctioning zone damper.
• Poor airflow or humidity issues - Weak airflow from vents or a noticeable increase in indoor humidity can signal a clogged filter, a blocked coil, or a blower motor nearing its end of life.
• Visible leaks - Any moisture around your indoor units or persistent puddling near the drain lines indicates a clog or a cracked condensate pan that can lead to structural damage.
