Environmental Test Chamber Preventative Maintenance

Even minor system issues can snowball into major disruptions. Routine environmental test chamber maintenance helps identify and resolve small inefficiencies before they become critical problems. Common issues we help prevent include:

• Poor airflow and circulation

• Dust or debris buildup

• Mineral contamination in humidity systems

• Drainage failures

• Interior corrosion

• Compressor breakdowns

• Temperature control malfunctions

Avoid these setbacks by investing in routine performance checks and scheduled maintenance visits from AES-certified technicians.

During each scheduled visit, our expert team performs a comprehensive inspection of your chamber’s core systems. Depending on your chamber type, our preventative maintenance service can include up to 85 specific checks. These typically cover:

• Verifying chamber performance and functionality

• Checking refrigeration and humidity systems for proper operation

• Evaluating refrigerant charge, line pressures, and temperature ranges

• Assessing electrical components, voltage, and amperage levels

• Performing ISO/IEC 17025 accredited calibration (as needed)

• Identifying potential signs of wear, stress, or part failure

Our technicians will also provide maintenance documentation and recommendations for future service needs.

We offer flexible PM agreements to match your test schedules and compliance needs:

• Quarterly Maintenance Plans for high-use or critical test applications

• Annual Maintenance Plans for standard chamber upkeep

• Custom plans available for multi-chamber facilities or remote labs

AES supports test chambers of all types and from all manufacturers—not just our own.

What is the recommended timeline for preventative maintenance? 

It’s best practice to receive quarterly preventive maintenance services and calibrations every six months to a year. For critical applications, though, or mandated regulatory standards, you may need to get your chamber serviced more frequently, such as quarterly. To keep your test chamber running smoothly, you should stay on schedule with your test chamber services. 

Do I need to turn off the test chamber during maintenance fully? 

To ensure safety and the best results, you should always shut your chamber completely off during maintenance. 

What signs indicate my test chamber needs service?

If your test chamber is beginning to show signs of imminent repair, there may be water leaks, rust, corrosion, pooling, or condensation—just to name a few issues. It’s important to get help right away. 

Does AES have any resources on doing a preventative maintenance checks on my own time?
