Packaged Rooftop Unit Replacement. Replacing rooftop HVAC equipment with new modern equivalent per industry standards.


This is a standard “like-for-like” rooftop package unit (RTU) swap wherein, we remove old equipment, replace with the modern equivalent and connect to existing wiring, drain systems, turn on and test. There are no enhancements to the duct work, new wiring installations or configurations to existing plumbing systems.

Step 1: Perform required lockout/tag out safety protocol as per NFPA70E of all high-voltage electrical circuits prior to beginning work on the existing unit.

Step 2: Remove and dispose of existing rooftop package unit in compliance with EPA regulations.

Step 3: Furnish and install new down-flow or side discharge package unit within existing unit footprint with matching specifications.

Step 4: Furnish and install provisions for electric heat kit or gas pack connections as required.

Step 5: Furnish and install new custom sheet metal curb as/if required to accommodate new unit on existing opening.

Step 6: Connect existing electrical power wiring and low voltage thermostat wiring to new unit.

Step 7: Connect existing drain line and route to nearest approved condensate disposal location. Unless specifically noted in the quote, this does not include connecting to internal plumbing systems inside the building.

Step 8: Provide crane, rigging and pro-lift equipment in order to facilitate removal and replacement of the rooftop package unit.
