Rooftop Units (RTUs) — Commercial & Industrial Installation, Replacement, and Service

Packaged comfort on the roof, reliable performance inside. Rooftop units cool (and often heat) your space from a single, self-contained unit mounted on the roof—ideal for offices, retail, restaurants, warehouses, and light industrial spaces.

When to consider an RTU upgrade

  • 12–15+ years old, frequent breakdowns, or rising energy bills
  • Hot/cold spots, poor airflow, or noisy operation
  • Older refrigerant models that are hard to service
  • Expanding or reconfiguring your space and need more capacity

How installation/replacement works

  1. Site survey: We verify tonnage needs, check electrical/gas, curb size, duct connections, and crane access.
  2. Options & clear quote: Right-sized equipment with choices like economizers (bring in cool outdoor air to save energy), high-efficiency fans, and smart controls.
  3. Permits & scheduling: We handle permits, safety plan, and coordinate an off-hours crane lift to minimize downtime.
  4. Lift, set & start-up: We fit a curb adapter (so the new unit matches your existing roof opening), reconnect power/gas/controls, commission the unit, and balance airflow.
  5. Inspection & handoff: Final checks, controls walk-through for your team, and a maintenance plan to keep it running right.

Service & maintenance (all brands)

  • Seasonal care: filters and belts, coil cleaning, drain service, electrical checks, refrigerant verification, economizer testing.
  • Repairs: compressors, fans, contactors, gas heat sections, sensors, control boards.
  • Upgrades: demand-control ventilation, VFD fan retrofits, smart thermostats/BAS integration, improved filtration for better air quality.

Why businesses choose RTUs

  • Fast, clean rooftop swap with minimal disruption
  • Scalable—from single 3–25 ton units to multi-unit setups
  • Easy access for service; less equipment on the floor
