September 2026
A Galveston homeowner in the 77550 area reported that their AC was not working.
Brandon found a backed up condensation line and a tripped float switch in the pan. He vacuumed the clog from the drain line and flushed it with water from the attic down to the vacuum outside, getting a ton of debris out. He then reset the float switch.
The drain was flowing freely and the system was running and cooling as normal.
Adrian
September 2026
A Galveston homeowner reported the system was not cooling well and thought it may just need a tune up.
Adrian found that everything seemed to be running really well, but the humidity was pretty high. He traced it to the fresh air damper, which was sticking open. Adrian left the fresh air damper closed so the unit can be replaced.

Aaron and Brandon are awesome and came to the rescue with our AC system thats not the normal brand type. They figured out the issue, very responsive and were generally just excellent. Will be joining their monthly plan as the AC systems really take a beating on the island, with the salty air and the multitude of power outages over the summer.

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.
Salt air accelerates corrosion on outdoor condenser units, refrigerant lines, and electrical connections. This can reduce system lifespan by 30-50% without proper coastal protection measures like marine-grade coatings and corrosion-resistant components.
We recommend twice-yearly maintenance for coastal homes: once before summer and once after. The salt air and humidity demand more frequent filter changes and coil cleanings compared to inland properties.
We typically recommend 16+ SEER2-rated systems for coastal properties. Higher efficiency units handle the constant humidity load better and save significantly on energy costs over their lifetime.
Yes. We offer retrofit corrosion protection packages including condenser coil coatings, weatherproof electrical connections, and marine-grade cabinet treatments that extend the life of your current system.
