What’s Included in Preventive Maintenance

System Evaluation

Technicians assess HVAC performance across all systems, including temperature consistency, airflow, and responsiveness. Early signs of wear or inefficiency are flagged for attention.

Filter and Vent Check

Air filters, ducts, and ventilation points are inspected and cleaned. This improves airflow, supports indoor air quality, and helps avoid strain on the system.

Electrical and Safety Inspection

Wiring, control panels, and thermostat settings are examined to ensure safe operation. Any faulty connections or misaligned controls are corrected.

Lubrication and Adjustments

All moving components receive lubrication as needed. Mechanical settings and tension points are adjusted to manufacturer guidelines to reduce wear and noise.

Seasonal Readiness Testing

Heating systems are tested before colder months, and cooling systems before warmer seasons. This confirms readiness and performance ahead of peak demand.
