Commercial buildings have heating and cooling demands that differ significantly from residential properties. Higher occupancy, larger floor plans, specialized ventilation requirements, and varying usage patterns all influence the type of HVAC system a building needs. QC Mechanical designs, installs, and services a full range of commercial equipment.
Rooftop package units (RTUs) are among the most common systems for small to mid-size commercial buildings. These self-contained units sit on the roof and deliver conditioned air through ductwork to the occupied space below. They are efficient, accessible for maintenance, and do not take up valuable interior square footage. For larger or more complex buildings, variable refrigerant flow (VRF) systems offer precise zone control and energy efficiency by routing refrigerant to multiple indoor units from a single outdoor compressor.
- Rooftop package units (RTUs) for offices, retail, and restaurants
- Variable refrigerant flow (VRF) systems for multi-zone buildings
- Split systems and ductless mini-splits for supplemental comfort
- Make-up air units and kitchen ventilation for food service
- Packaged terminal units for hotels and multi-family properties
- Building automation system integration
