Installation
Precision installs, from air handlers to full plants.
A commercial installation is mostly decided before any equipment arrives. Sizing against the actual load rather than the nameplate of the unit being removed, checking that the existing curb, electrical service, and duct can carry the new equipment, and planning the rigging are what separate an install that runs quietly for fifteen years from one that generates service calls in year two.
We handle equipment replacement and new installation for rooftop package units, split systems, air handlers, condensers, and hydronic equipment. Scope includes load review and right-sizing, curb adapters or new curbs, electrical and control tie-in, crane and rigging coordination, permitting where required, and start-up and commissioning with documented readings.
Where a building has changed, the replacement is a chance to correct the original mistake instead of repeating it. Tenant improvements, added server rooms, and changed occupancy frequently mean the outgoing unit was the wrong size for years, and matching the new equipment to today's load is where the operating savings actually come from.
What this service covers
- Load review and equipment right-sizing
- Rooftop package unit replacement and new installation
- Split system, air handler, and condenser installation
- Curb adapters, new curbs, and roof penetration detailing
- Electrical service and control tie-in
- Crane and rigging coordination
- Permitting and code-compliant installation
- Start-up, commissioning, and documented performance readings
It is time to price a replacement when
- Repair cost is approaching a meaningful share of replacement cost
- The unit is past its service life and parts are getting hard to source
- The building load changed and the equipment no longer matches it
- Efficiency has dropped far enough that operating cost justifies the capital
- You are planning a tenant improvement and the mechanical scope needs to be priced with it
Installation questions
How long does a commercial rooftop unit replacement take?
A straightforward like-for-like rooftop changeout is often a single day once the equipment is on site and the crane is scheduled. Lead time on the equipment itself is usually the longer part of the timeline, and we tell you that up front.
Do you handle the crane, permits, and inspection?
Yes. We coordinate rigging and crane scheduling and handle permitting where the jurisdiction requires it, so the replacement is one scope rather than several vendors you have to sequence yourself.
How do you decide what size unit to install?
We size against the building's actual load, not the nameplate of the unit coming out. If the space has changed since the original install, the outgoing unit is frequently the wrong size, and repeating that mistake costs you every month it runs.
