What Caused My Heat Pump to Stop Working in Galveston?
The Problem
A homeowner in Galveston was experiencing issues with their HVAC system, which was unable to maintain a comfortable temperature throughout their home.

Why quality ductless mini-split matters in Galveston
Salt Air Corrosion
Galveston Island's direct ocean exposure means HVAC outdoor units face constant salt spray that corrodes condenser coils, electrical connections, and cabinet panels far faster than inland locations. Coastal-rated equipment and frequent cleaning are essential.
Extreme Humidity
Galveston's humidity regularly exceeds 80%, forcing AC systems to handle heavy moisture removal alongside cooling. Without proper dehumidification, homes experience clammy air, mold growth, and premature equipment wear.
Hurricane & Storm Exposure
Galveston's island location makes HVAC systems vulnerable to hurricane-force winds, storm surge, and power surges. Proper equipment anchoring, surge protection, and post-storm inspections are critical for system longevity.
Year-Round Cooling Demand
Galveston's mild winters and long, hot summers mean AC systems run 8-9 months per year — significantly more than inland areas. This extended runtime accelerates wear on compressors, fans, and electrical components, making proactive maintenance essential.

Ductless Mini-Split in Galveston: questions answered
Answered by our licensed technicians serving Galveston.
Is a ductless mini-split a good option for older Galveston homes?
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 15-25% efficiency loss from pushing cooled air through a 150-degree attic.
How much does a ductless mini-split cost in Galveston?
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 last 2-3x longer in salt air.
Do mini-splits handle Galveston's humidity?
Modern inverter mini-splits handle it very well. They run continuously at variable speeds, pulling far more moisture from the air than systems that cycle on and off. Many models also include a dry mode that prioritizes dehumidification — ideal for Gulf Coast shoulder-season days that are 75 degrees but 90% humidity.
Will a standard mini-split outdoor unit survive the salt air?
Not for long. We've seen standard units with condenser coils corroded to half capacity after three years on Galveston Island. We install only units with Blue Fin or Gold Fin coil coatings, stainless hardware, and marine-grade cabinet finishes. For beachfront properties, we add wind baffles and elevated mounting.
How long does mini-split installation take?
Single-zone installations complete in 4-6 hours. 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 rated for hurricane-force wind-driven rain.
