Commercial Service & Installation

HVAC Solutions for Businesses and Property Managers

Commercial HVAC systems must meet performance, reliability, and code requirements to keep employees productive and occupants comfortable. Maci Mechanical offers design, installation, and maintenance services for commercial properties in Tinley Park and the surrounding region. From rooftop units to packaged systems, we provide professional solutions tailored to building type, occupancy, and energy goals.

Design & Engineering for Commercial Projects

Commercial projects require careful planning and coordination with general contractors, architects, and building owners. Our approach includes:

HVAC system in a small room with a water heater and a floor opening. Gray and white interior.

Load calculations and system selection based on building use and occupancy schedules

Recommended equipment types: packaged rooftop units, multi-zone systems, VRF/mini-split for certain applications, and dedicated ventilation systems

Integration with control systems and building automation (scheduling, remote monitoring)

Energy efficiency planning: variable frequency drives (VFDs), economizers, and demand-based ventilation

Coordination of mechanical, electrical, and structural needs for rooftop units and duct routing

The Maci Mechanical Installation Process

We attend design meetings, review drawings, and develop installation plans that comply with codes, structural limitations, and project timelines.

Pre-Construction & Planning

equipment procurement

As an authorized dealer for recognized equipment lines, we source reliable units and coordinate delivery times. We select robust systems suited for high duty cycles.

professional installation

Our crews install equipment per manufacturer and code requirements, including rooftop curbs, structural supports, proper refrigeration piping, electrical hook-ups, duct transitions, and start-up procedures.

commissioning & verification

We commission systems to verify airflow, controls, temperature performance, and safety interlocks. This stage ensures systems perform as designed and meet the building’s needs.

aftercare maintenance

We offer preventative maintenance tailored to commercial demands: routine filter changes, coil cleanings, compressor checks, and monitoring to prevent costly downtime.

Cleanup & Documentation

We remove old equipment (disposal in accordance with local regulations), clean the work area, and provide documentation including manufacturer warranty registration and recommended maintenance schedule.

Energy Management & Savings

Commercial HVAC energy management can produce large operational savings. We implement strategies like:

  • Economizers and demand-controlled ventilation
  • Building automation with scheduling and remote monitoring
  • Variable speed drives to match load demands
  • Zoning strategies to condition occupied areas efficiently
  • Recommend equipment upgrades (higher EER/SEER or more efficient boilers and chillers)

Compliance & Indoor Air Quality Standards

Commercial facilities face regulations for ventilation and indoor air quality. We design systems to meet local code and ASHRAE guidelines:

  • Adequate outdoor air ventilation per occupancy
  • Filtration upgrades to improve particle removal
  • ERV/HRV solutions to recover energy while providing fresh air
  • Testing and balancing to ensure proper distribution of conditioned air
