Burbank Commercial AHU Repair for Lennox Systems

What we repair on Lennox commercial AHUs

From small air handlers to large multi‑zone Lennox commercial systems, our engineers bring a deep, methodical approach to every repair. We service both split and packaged air handler configurations and resolve performance problems that cause comfort drift, poor IAQ, and high energy use.

• Fan assemblies: blower wheels, housings, shaft alignment, bearings, and vibration correction
• Motors and drives: ECM and induction motors, starters, soft‑starts, and VFD troubleshooting or replacement
• Coils and heat exchange: chilled water coils, DX coils, hot water coils, fin cleaning, leak checks, and freeze protection
• Airflow path: filters, MERV upgrades, belt tensioning, pulleys, seals, and plenum integrity
• Dampers and economizers: linkages, actuators, blade seals, and outdoor air calibration
• Controls and BAS: sensors (temp, RH, CO2), safeties, sequence logic, and integration with building automation
• Drainage and casing: pans, traps, microbial growth remediation, access doors, and insulation repair

Engineer‑led diagnostics that fix root causes

We do more than swap parts—we locate the root cause and validate results with data.

Our diagnostic workflow:
• Verify design intent and Lennox AHU model data
• Measure static pressure, airflow, and temperature split
• Test drives, motors, capacitors, and electrical health under load
• Assess coil condition, refrigerant circuit (if DX), and valve operation
• Calibrate sensors and check sequences in your BAS
• Balance outdoor/return/exhaust for code‑aligned ventilation

Deliverables you can trust: a clear fault report, photos, and a step‑by‑step repair plan with options for uptime, efficiency, and IAQ.

Upgrades and IAQ improvements for Lennox AHUs

As part of repair or planned retrofit, we can modernize your Lennox air handler to extend life and improve indoor environmental quality.

• MERV filtration upgrades with static pressure verification and fan re‑profiling
• UV‑C coil irradiation and coil deep‑clean programs to control biofilm
• VFD retrofits for demand‑based airflow and energy savings
• Economizer tuning and fault detection to reduce mechanical cooling hours
• CO2‑based demand control ventilation to meet ASHRAE 62.1 intent
• Sensor upgrades (temperature, humidity, CO2) and BAS optimization

Outcome: cleaner air, steadier temperatures, quieter operation, and lower operating cost—without compromising capacity.
