Preventative Maintenance
Commercial HVAC Preventative Maintenance Programs by Nexklima Inc.
Unplanned mechanical failures disrupt operations, impact tenant satisfaction, and create budget-draining emergency repair bills. Nexklima Inc. designs and executes structured commercial HVAC preventative maintenance programs tailored to your facility’s exact equipment footprint, operating hours, and thermal loads.
By replacing reactive repairs with routine, scheduled maintenance, we keep your commercial chillers, boilers, rooftop units, and air handlers running at peak thermodynamic efficiency.
Comprehensive Inspection & Service Protocols
1. Air Handling & Packaged Unit Servicing
Rooftop units (RTUs), make-up air units (MAUs), and split systems require regular care to maintain airflow and indoor air quality.
- Filter & Airway Maintenance: High-efficiency MERV filter replacements, intake screen cleaning, and duct static pressure checks.
- Drive & Blower Care: Belt tensioning, sheave alignment, bearing lubrication, and motor amperage verification.
- Coil Hygiene: High-pressure chemical washing of evaporator and condenser coils to remove debris, restore heat transfer, and prevent compressor strain.
2. Central Plant & Hydronic Maintenance
Chillers, boilers, and circulating pumps form the thermal spine of large commercial properties.
- Refrigerant & Pressure Diagnostics: Operating pressure verification, superheat/subcooling checks, and electronic leak detection.
- Burner & Combustion Calibration: Flue-gas analysis, burner profile adjustments, and safety interlock testing on commercial boilers.
- Water Loop Audits: Expansion tank pressure checks, strainer cleaning, and pump seal inspections.
3. Electrical & Safety Control Calibration
Preventable electrical failures cause a majority of major mechanical breakdowns.
- Thermal imaging scans of electrical disconnects and contactors
- Tightening loose line-voltage and control-wiring terminations
- Testing crankcase heaters, high/low pressure cutouts, and freeze-stat safeties
Technical Inspection Checklist Matrix
| Frequency | Equipment Focus | Primary Maintenance Objectives |
|---|---|---|
| Monthly | Chillers, Boilers, Cleanrooms | Critical operating log audits, fluid leak checks, safety switch verification |
| Quarterly | RTUs, Air Handlers, Exhaust Fans | Air filter replacements, belt adjustments, condensate drain line flushing |
| Semi-Annually | VRF, Heat Pumps, Controls | Seasonal switchover checks, sensor recalibrations, electrical terminal tightening |
| Annually | Entire Central Plant | Chemical coil washing, compressor oil analysis, heat exchanger eddy-current testing |
Frequently Asked Questions
How often should a commercial building schedule HVAC preventative maintenance?
Commercial facilities require quarterly maintenance at minimum (4 times per year) to address seasonal shifts. High-demand assets like central chiller plants and boilers should undergo monthly operational checks.
Does regular preventative maintenance lower utility bills?
Yes. Dirty coils, slipping belts, low refrigerant levels, and clogged filters force equipment to work harder, increasing energy consumption by 15% to 30%. Routine care restores optimal performance.
