Mini-splits are the most efficient way to heat or cool a room without ductwork. Perfect for additions, garages, sunrooms, or older homes — United National HVAC installs and services all major mini-split brands.
Ductless mini-split installation in Mckinney, TX is the cleanest solution for additions, garages, sunrooms, and older homes without existing ductwork. United National HVAC installs and services single-zone and multi-zone mini-split systems throughout Collin County.
Many homes in Stonebridge Ranch, Craig Ranch, and Historic Downtown and across Mckinney (75069/75070/75071/75072) have bonus rooms, converted garages, or additions that were never connected to the main duct system. A mini-split handles these spaces efficiently without major renovation — and it provides both heating and cooling year-round.
We install major mini-split brands including Mitsubishi, Daikin, LG, and Carrier. Installation typically takes 4–8 hours for a single zone with minimal wall penetration required. Financing from $49/mo is available and systems typically qualify for federal energy efficiency tax credits.
