Typical rooftop HVAC lifts
- Setting new package units or RTUs on curbs
- Change-outs, where the old unit comes down and the new one goes up in the same visit
- Condensers, air handlers and exhaust fans on commercial roofs
- Removing abandoned equipment before a re-roof
What to have ready
- The unit's weight from the manufacturer's spec sheet or submittal, plus the old unit's weight if it's coming down
- Building height, and how far the unit sits from where a crane could park. Reach (radius) often matters more than height.
- Where the crane can set up: parking lot, street, alley or dirt lot
- Overhead power lines, trees, canopies or anything else in the swing path
- Whether your mechanical crew, curb adapter and rigging will be ready when the crane arrives
Tips that make the lift go smoothly
Have the HVAC crew disconnect the old unit and prep the curb before the crane shows up, so crane time is spent lifting. If several units are going on the same roof, put them in one request. Doing them in one visit is usually more efficient than booking separate trips.
For businesses that can't close, ask about early-morning or weekend lifts when the lot is empty. For the Yuma-specific version of this page, see rooftop AC crane lifts in Yuma.
