Pro Tip
If your AC isn't cooling effectively, it might be a refrigerant issue. Regularly check for unusual noises or leaks around your unit to catch problems early, potentially saving on costly repairs.
Why quality evaporator coil services 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.

Evaporator Coil Services in Galveston: questions answered
Answered by our licensed technicians serving Galveston.
Why does my evaporator coil keep freezing in Galveston?
The three main causes are low refrigerant (from salt-corroded copper lines creating pinhole leaks), restricted airflow (clogged filter, collapsed duct sections, or failing blower motor), and a dirty coil surface acting as insulation. In Galveston's humidity, ice builds up much faster than in dry climates — a coil can freeze solid in 30-60 minutes.
Is a frozen evaporator coil dangerous in humid climates?
Yes. When the ice melts, the water volume in Galveston's humid air overwhelms drain pans and condensate lines. In dry climates you get a small puddle. On the Gulf Coast, a frozen coil thaw can flood ceilings, saturate insulation, and create mold-friendly conditions within hours.
What should I do if my evaporator coil is frozen right now?
Turn your thermostat to fan only — not off. This circulates room-temperature air to thaw the coil gradually. Place towels around the air handler base. Don't chip ice off — you'll damage fins and potentially puncture copper tubing. Let it thaw fully (1-3 hours), then call for service before turning cooling back on.
How often should evaporator coils be cleaned on the Gulf Coast?
At least annually as part of your tune-up. Our $129 coastal tune-up includes evaporator coil inspection and cleaning. We routinely see 10-15 degree improvements in temperature split after cleaning a neglected coastal coil — that translates directly to better cooling, lower humidity, and reduced energy bills.
How much does evaporator coil replacement cost?
Typically $800-$2,500 depending on coil size, refrigerant type, and accessibility. For coastal replacements, we recommend coils with factory-applied corrosion coatings when available, and we verify the air handler cabinet is properly sealed to minimize future salt infiltration.
