Signs your AHU needs immediate attention

• Unstable temperatures, humidity swings, or persistent hot/cold zones
• Excessive noise, vibration, or belt dust
• Rising energy bills or frequent breaker trips
• Odors, visible dust, or complaints about air quality
• Frosting coils, condensate overflow, or water near the unit

Addressing these early prevents major failures and protects occupants’ health and productivity.

Indoor air quality (IAQ) matters

Our mission is healthy air for a healthy life. We tune AHUs to deliver the right mix of filtration, ventilation, and dehumidification. From MERV upgrades and coil hygiene to economizer optimization, we help you meet IAQ goals with measurable results.

Maintenance and prevention

After repairs, we can set proactive service intervals to protect motors, reduce coil fouling, maintain correct belt tension, and keep controls calibrated. This extends AHU life and stabilizes tenant comfort.
