A Galveston homeowner in the 77550 area reported that their coil needed to be cleaned.
Adrian found a dirty coil. He pulled the evaporator coil and cleaned it to the best of his ability.

A Galveston homeowner in the 77551 area asked the team to look for a leak in their air conditioning system.
Adrian and Gamaliel performed an electronic leak search and found many extremely small leaks in the evaporator coil. They replaced the evaporator coil under warranty and replaced the filter dryer using a pump down. They then completed a vacuum and recharge, adding R-410A refrigerant, and restored the system.
The system was restored to operation with the new evaporator coil and filter dryer in place.

August 2026
A Galveston homeowner in the 77550 area repeatedly reported that the AC was not cooling, the upstairs was not cooling, and the house was not cooling below 75 at night. Other visits noted the motor not running, the unit making noise, and the outdoor unit not coming on.
Over 16 summer visits, Adrian, Gamaliel, Brandon, Matthew, Gabriel, Aaron, and Christian found an outdoor unit with 700psi head pressure that tripped the breaker, backed-up drain lines with a tripped float switch, a bad blower motor, a restricted metering device and filter drier, a blown fuse, and a leak on the filter dryer inside the condenser. The team installed a new 5 ton R410A Luxaire condenser, pulled and chem washed the evaporator coil, pulled the system down to 500 microns, and added 6 pounds of R410A. On later visits they replaced the blower motor, flushed drain lines, replaced the drain pan and added a float switch, hung and re-attached ductwork, replaced the metering device and filter drier, built a new return plenum, added a new blower capacitor, replaced a blown fuse, and repaired the filter dryer leak before vacuuming and recharging the system.
After the condenser replacement the system reached a 20-degree delta-T with 15 sub-cooling, and later checks showed splits of 18 to 23 degrees with the unit working properly.
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.
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.
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.
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.

Answered by our licensed technicians serving 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.
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.
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.
At least annually as part of your tune-up. Our $225 AC 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.
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.
