Quick Answers: HVAC in North Texas
How do you size a mini-split for a Texas garage or bonus room?
We size by the load, not by square footage. A West-facing North Texas garage with an uninsulated overhead door and a hot attic above pulls far more heat than a shaded interior room of the same size, so we run a room-by-room load calculation that accounts for orientation, insulation, glass, and ceiling height. Get the BTU sizing wrong and an oversized inverter short-cycles (poor humidity control) while an undersized one runs flat-out and never catches up. Typical garages and bonus rooms here land on a 9,000-18,000 BTU single zone.
Single-zone or multi-zone mini-split - which do I need?
If you are conditioning one space - a converted garage, a sunroom, a new addition - a single-zone system with one outdoor condenser and one indoor head is simpler, cheaper, and slightly more efficient. Choose a multi-zone (one outdoor unit feeding several indoor heads) when you want independent temperature control in multiple rooms, such as a primary suite plus a home office plus a bonus room. Multi-zone keeps the outdoor footprint and refrigerant runs to a minimum, which matters on HOA-governed lots.
Can a mini-split fix a room my central AC never cools?
Usually, yes - that is one of the best uses for ductless in North Texas. Rooms over a garage, far additions, and finished attics are common dead spots because the central system cannot push enough air that far. A dedicated mini-split with no ductwork removes the duct-loss problem entirely and lets that room hold its own setpoint without overcooling the rest of the house.
No Ductwork? No Problem.
When you add a room, finish a garage, or convert a bonus space, extending the central system rarely works - the existing trunk and air handler were not sized for the extra load, and snaking new flex into a hot attic just spreads the comfort problems around. A ductless mini-split is a self-contained inverter heat pump: one outdoor condenser, a small refrigerant line set, and a wall, ceiling-cassette, or floor head that conditions the space directly. No new ducts, no duct losses, and precise zone control down to a single room. If the rest of the house has uneven temperatures too, ask about a zoned HVAC setup or a proper duct redesign.
