Takes about a minute. No obligation.
Sizing and refrigerant charge have to be right before a contractor closes up the installation, because there is no shoulder season to hide a marginal setup. Homes in Van Buren County, AR run cooling about four months a year, from June through September. The compressor starts and stops through that entire stretch, and a unit that was installed with sloppy line sets or an imprecise charge runs harder than it should on every one of those cycles. A licensed contractor checks the load calculation against the actual floor area and envelope before specifying the head units, not after.
Electrical service panels in houses built for earlier generations of equipment are the variable a contractor has to settle before anything else on a mini-split job. Half the homes in Van Buren County, Arkansas were built in 1986 or earlier (2020-2024 ACS 5-year). A house wired under the assumptions of that era was sized for a different load profile than a modern inverter-driven unit draws, and the panel is where a contractor finds out whether the quoted system can actually run as specified. The ductwork question does not apply to a ductless install, but the electrical does, and in stock of this vintage it is where jobs stall or change scope.
The Mini-split Components a Contractor Sizes and Places
The indoor air handler mounts high on a wall inside the room and delivers conditioned air directly into that space. The outdoor unit sits on the ground or a bracket outside the house and holds the compressor and condenser coil. Together, those two pieces are what a contractor accounts for when planning a mini-split installation.
A refrigerant line set runs through a small hole in the wall to connect the indoor and outdoor units, and a condensate drain line carries moisture away from the air handler to the outside. A control board inside the outdoor unit manages the system, and the indoor unit takes a signal from a handheld remote or a wall-mounted thermostat.
The drawing shows a typical layout, and a licensed contractor determines exactly where each component goes and how the line set routes through your specific home.
