Overview

A premium take on cambio de equipo / system change-outs

When an aging system costs more to keep running than it's worth, a change-out replaces the old equipment with a new, efficient system using your existing ductwork and connections wherever possible. We size the new equipment for your building rather than simply matching the old label, recover the old refrigerant properly, flush or replace line sets as needed, and set the new unit on a level pad. Every change-out finishes with a full startup test, so you know the system is performing the way it should.

This service is a good fit for homeowners and property managers who want a clean, professional result without juggling the details themselves. We handle the prep, the finish work, and the cleanup so the space is ready to enjoy when we're done.

Every project covers the essentials

  • AC, heat pump, and furnace replacements
  • Equipment sized to the building, not the old unit
  • Proper refrigerant recovery and disposal
  • Line set flush or replacement, new pad and disconnect
  • Thermostat setup and full startup test
  • Written price and install date before we begin
