Takes about a minute. No obligation.
A contractor quoting a mini-split install in Armstrong County has to size the system around what the climate actually demands, and that means working from local load figures rather than catalog defaults. 162 severe weather events were recorded in Armstrong County, Texas between 2015 and 2024. At that rate of severe weather, an undersized unit runs harder and longer to hold temperature during stress events, and the strain shows up sooner in the compressor and refrigerant lines than it would in a calmer area. A contractor who ignores that record and pulls a standard size for a house of similar square footage is leaving the homeowner with a system built for conditions this county does not have.
Electrical service is what a contractor has to settle before anything else moves forward on a mini-split job here. Half the homes in Armstrong County, Texas were built in 1965 or earlier (2020-2024 ACS 5-year). Homes built by that point were wired for the loads of their time, and a modern mini-split draws differently than what those circuits were sized for. The ductwork question is simpler with mini-splits than with central systems, but the panel still has to be opened and read before a contractor can tell a homeowner what the full job costs.
The Parts of a Mini-Split System and What HVAC Installation Covers
The indoor air handler mounts high on an interior wall in the room being conditioned. It draws room air across its coil and pushes conditioned air back into the space. The outdoor condenser unit sits outside the house, typically on a pad or bracket along an exterior wall, and houses the compressor and the coil that faces the open air.
A refrigerant line set runs through a small penetration in the wall to connect the indoor and outdoor units, carrying refrigerant between the two. A condensate drain line runs from the indoor head to carry away moisture, and a control wire ties the two units together so they operate as one system.
The drawing shows the general layout of a mini-split system, and a licensed contractor determines exactly how each piece applies to your house.
