Ductless Mini-Split
July 2026 · La Marque · Adrian & Gamaliel
A La Marque homeowner reported that the mini split unit was not working.
The unit was not cooling, and the suction line manifold was still shut closed. Adrian and Gamaliel opened it and tested the unit. They also found the line set kinked and the filters dirty, so they unkinked the lines and cleaned the filters.
After the manifold was opened, the unit was tested and everything was operating well.

Answered by our licensed technicians serving La Marque.
It's often the best option. Many island homes (historic raised cottages, pier-and-beam Victorians, beach bungalows) either have no ductwork or have badly retrofitted ducts that leak at every joint. Mini-splits bypass ductwork entirely, avoiding the $3,000-$8,000 cost of new duct installation and the cooling lost when ducts run through a hot attic.
Single-zone installations with corrosion-rated equipment run $3,000-$5,500. Multi-zone systems (2-5 indoor units on one outdoor compressor) range from $8,000-$15,000. Corrosion-rated outdoor units cost $300-$800 more than standard models but hold up much better in salt air.
Modern inverter mini-splits handle it well. They run at variable speeds for long stretches, pulling more moisture from the air than systems that cycle on and off. Many models also include a dry mode that prioritizes dehumidification, ideal for mild but muggy Gulf Coast shoulder-season days.
Not for long close to the water. We install units with factory-applied coil coatings, stainless or coated hardware, and marine-grade cabinet finishes. For beachfront properties, we add elevated mounting and wind baffles.
Most single-zone installations complete in a day. Multi-zone systems take 1-2 days depending on the number of indoor units and routing complexity. The wall penetration is a 3-inch hole sealed with weatherproof compounds to keep out wind-driven rain.
