A cooling system is only as good as the install. Equipment that is oversized short-cycles, pulls less humidity out of the air, and wears out early — and oversizing is the single most common mistake we find when we open up somebody else's work. We size from a load calculation, not from what was there before.

The install includes the parts people cut corners on: a properly brazed and evacuated line set, a verified charge weighed in rather than guessed at, a correctly pitched condensate path, and a return that can actually move the air the equipment is rated for. We go over the options and the operating cost differences before anything is ordered.

What this covers

  • Manual J-style load calculation, not rule of thumb
  • Straight-cool, heat pump and dual-fuel options
  • Line set evacuation and weighed-in charge
  • Duct and return modifications where airflow requires it
  • Old equipment and refrigerant removed and handled properly
  • Manufacturer warranty registration
