AC installation in Port Charlotte starts with a load calculation, not a guess from the old unit's label. Plenty of homes here got a 4-ton system decades ago because that is what was on the truck that day. Oversized equipment short-cycles. It cools the air fast and shuts off before it pulls the moisture out, and the house ends up cold and clammy.
We run a Manual J style calculation using your square footage, window area, insulation, orientation and ceiling height. A concrete-block ranch in a 1970s Port Charlotte neighborhood with original single-pane windows loads very differently than a newer home with impact glass and spray foam in the attic.
Florida requires permits for HVAC installs and change-outs, and Charlotte County inspects the work. We pull the permit. Outdoor equipment has to be anchored to the pad for wind load, and we set the condenser on a raised pad where flood exposure calls for it.
For efficiency, the federal minimum for new split air conditioners in the Southeast is 15 SEER2 for most residential sizes. We will show you how a variable-speed system compares on humidity control, which is where the difference shows up in our climate.
AC installation day includes a new line set or a flush of the old one, a new drain line with a float switch, a nitrogen pressure test, a deep vacuum checked with a micron gauge and a full start-up check. If your current system is on its last legs, see our AC replacement page.
