Sizing a mini-split for a home in Lampasas County starts with what the house actually demands, not with assumptions about weather beating the equipment into early failure. 46 severe weather events were recorded in Lampasas County, Texas between 2015 and 2024. At that rate, severe weather is an occasional fact of life here rather than a standing condition, and a contractor quoting a new installation is not building in extra margin to compensate for relentless load. What drives the specification is the structure: orientation, insulation, square footage, and where the air handler sits. A system installed correctly for those variables will perform without weather being the variable that decides the outcome.
Older electrical service is the variable that sets the pace on a mini-split installation here, not the equipment selection itself. Half the homes in Lampasas County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). Homes built by that year were wired for the loads of that era, and a mini-split draws power in ways that wiring was never planned around. A contractor has to establish what the panel can actually deliver and whether the circuits serving the installation space meet current draw requirements before the job can move forward.
The Parts of a Mini-Split System and What Gets Assessed
The indoor air handler mounts high on a wall inside the room being served. It pulls in room air, conditions it, and pushes it back out. The outdoor condenser unit sits outside the home, usually along a side wall or at ground level on a pad, and carries the other half of the system.
A refrigerant line set runs between the two units through a small hole in the wall, carrying the connection that makes them work as one system. A condensate drain line runs from the indoor unit to an exit point, and a dedicated electrical circuit feeds the outdoor unit from the breaker panel.
The drawing here shows a typical layout, and a licensed contractor determines what applies to your specific home and setup.
