Commercial HVAC: A Different Scale

Commercial HVAC systems serve offices, retail spaces, restaurants, warehouses, and light industrial buildings. Unlike residential systems, commercial installs involve higher-capacity equipment, multi-zone controls, dedicated ventilation systems, and commercial-grade mechanical permits.

Our network includes commercial HVAC contractors who handle the full scope — from rooftop unit swaps to multi-zone VRF installations — with the licensing and insurance required for commercial work.

Commercial Systems We Install

  • Rooftop units (RTUs) — packaged heating and cooling for flat-roof buildings
  • VRF / VRV multi-zone systems — zoned comfort for offices and mixed-use spaces
  • Chillers and fan coil units — large commercial and light industrial applications
  • Commercial split systems — for smaller retail and restaurant applications
  • Commercial heat pumps — energy-efficient heating and cooling for modern buildings
  • Dedicated outdoor air systems (DOAS) — ventilation-focused commercial HVAC

FAQ

Commercial HVAC FAQ

What types of commercial HVAC systems do you cover?
Our network contractors install and replace rooftop units (RTUs), packaged systems, split systems, VRF/VRV multi-zone systems, chillers, fan coil units, and commercial heat pumps for offices, retail spaces, restaurants, warehouses, and light industrial buildings.
How is commercial HVAC sized differently from residential?
Commercial systems are sized using ASHRAE Manual N (for retail/commercial) rather than residential Manual J. Sizing accounts for occupancy loads, equipment heat gain, ventilation requirements, and zoning needs. Oversizing or undersizing commercial systems leads to poor humidity control and excessive energy costs.
How long does commercial HVAC installation take?
Timeline varies significantly by system type and building size. A rooftop unit replacement can take 1–2 days. A new multi-zone VRF system for a mid-size office may take 1–3 weeks. Your contractor will provide a project schedule after the site survey.
Do commercial HVAC installations require permits?
Yes. Commercial HVAC work requires mechanical permits in virtually all jurisdictions, and often requires licensed mechanical contractors (not just HVAC technicians). Our network contractors are qualified for commercial permitting.
What is a rooftop unit (RTU) and when is it the right choice?
An RTU is a self-contained packaged system installed on the roof — it handles heating, cooling, and ventilation in one cabinet connected to rooftop ductwork. RTUs are the most common commercial HVAC system for single-story retail, restaurants, and office buildings.
