What air conditioning installation & replacement involves
A proper AC installation includes load calculation, matched coil and condenser, correct lineset and charge, duct and static pressure evaluation, a properly pitched condensate route with a safety switch, and commissioning readings at the end.
Central air replacement matched to your ductwork and your house, with a real load calculation behind it.
