HVAC and Rooftop Unit Lifts Guide: Colorado's Front Range

Overview

Rooftop HVAC units, generators and other equipment often require crane lifts. These lifts involve coordination with mechanical contractors, building owners and sometimes street permits.

Lift planning considers unit weight, rigging, radius to the roof location and setup space. Early morning lifts are common in busy areas.

Rigging points and curb adapters should be prepared before the lift.

The usual process

Confirming unit weights.
Planning crane position.
Permits and traffic control.
Rigging and lift.
Setting the unit.

Things worth considering

Street permits may be needed.
Weather.
Building access may be limited.
Coordination with HVAC contractors.
Weights should include rigging.

Local notes for Colorado's Front Range

Wind along the Front Range, especially near the foothills, can affect crane operations, and lifts are postponed when conditions exceed limits. Altitude does not change crane load charts, but weather windows and ground conditions after snowmelt matter.

We take inquiries from Fort Collins, Boulder, Denver, Colorado Springs, Pueblo.

What to have ready

Note the lift height, reach or pour distance needed, measured from where the equipment would set up.
Tell us who the on-site contact will be on the day of the work.
Share your preferred dates, working hours and how long you expect to need the equipment or service.
List the heaviest and largest items or loads, with approximate weights and dimensions, or share the equipment spec sheet.
Mention whether you need an operator, rigging, delivery, permits or traffic control, or plan to handle those yourself.
Note any site rules, such as general contractor requirements, safety orientation, insurance certificates or restricted hours.
Include photos of the site and the setup area if you can.

Signs to slow down

No questions about loads, ground conditions or site access before quoting.
No written quote that lists equipment, minimum charges, travel, overtime and cancellation terms.
Vague answers about equipment inspection and maintenance records.
No clear answer about who is responsible for permits, traffic control or site preparation.
Unwillingness to provide insurance certificates or operator qualifications when asked.
Quotes that change significantly on the day without a clear reason.
Pressure to proceed without a lift plan or site visit on a complex job.
