RTU changeouts
Removing old units and setting new ones on existing curbs.
Swapping a rooftop unit? A crane can take the old unit off and set the new one in a single visit. Describe the lift and we'll pass it to providers that handle HVAC picks in the Killeen area.
Get a Free Crane QuoteA typical rooftop unit (RTU) changeout goes like this: the mechanical contractor disconnects and prepares the old unit; the crane lifts it off the roof curb and sets it on a truck or the ground; then the new unit — sometimes with a curb adapter — is lifted and set onto the curb. With good planning, several units on the same building can be swapped in one session.
Central Texas summers are hard on HVAC equipment, and many businesses can't be without cooling for long. Coordinating the crane, the mechanical crew and the building's schedule is the most important part of the job. Many lifts are done early in the morning or on weekends when parking lots and buildings are empty.
The operating weight of each unit (from the equipment submittal or nameplate), plus the weight of the old unit if it's coming off. The distance from where the crane can set up to the farthest unit, and the building height. Whether the crane can set up in a parking lot, drive lane or street, and whether that area can be cleared and closed off.
Rigging matters too: many RTUs have designated lifting points and require spreader bars so the slings don't crush the cabinet. If the building is occupied, the provider may need to plan the load path so it doesn't pass over people.

The more detail you include, the faster a provider can tell you which crane fits and what it will cost. Fields marked * are required.
General information to help you plan. Your crane provider has the final word on equipment, safety and pricing for your specific lift.
Pricing is set by each provider and depends on crane size, time on site, travel, number of units, rigging and whether it's after hours. Listing all units and their weights in one request usually gets the most useful quote.
Often, yes. Grouping the lifts into one visit saves setup and travel time. The crane has to be sized for the heaviest unit at the farthest reach, so tell the provider about all of them.
Usually part of it. The crane, outriggers and the area under the load path should be kept clear of people and vehicles during the lift. If you need to use a public street, check with the city about permits.
It varies. Some crane providers rig and set; others expect the mechanical crew to handle rigging and connections. Clarify it when you get your quote.
