Selecting a contractor for your AC setup
After shortlisting potential companies, contact them for quotes. A professional contractor can assist with installation, offer maintenance tips, and address technical questions. They will also perform cooling load calculations to recommend the appropriate AC size for your space.

Once you decide to proceed with a central or split AC system, expect the following steps, though details may vary by contractor:

  • Verify if local permits are required for installation; reputable contractors often handle permit procurement
  • Disassemble your existing AC system if necessary
  • If applicable, repair or replace ductwork to match the new system requirements
  • Install a concrete pad or rooftop support for the outdoor unit
  • Connect the indoor and outdoor units with correctly sized refrigerant, drain, and electrical lines
  • Set up the thermostat, clean refrigerant lines, and conduct a test run
  • Perform a final inspection to ensure proper functioning of the system
