AC Malfunctioned on a Windy Night in Galveston
The Problem
The homeowner noticed that their AC was not cooling the house despite running continuously.
What We Found
Adrian discovered that the AC's evaporator coil was frozen, likely due to restricted airflow or low refrigerant levels.
The Fix
Adrian carefully thawed the evaporator coil and checked the refrigerant levels. He also inspected the air filters and ductwork for any blockages that might have caused restricted airflow, ensuring everything was clear and functioning properly.
The Result
The AC system was restored to full functionality, providing cool air throughout the home once again.
Pro Tip
If your AC stops cooling and you notice ice on the unit, turn it off immediately to prevent damage. Check your air filter monthly — a clogged filter can cause freezing by restricting airflow.

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.

Why quality air conditioning 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.

Air Conditioning in Galveston: questions answered
Answered by our licensed technicians serving Galveston.
How does salt air affect my air conditioning system?
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.
How often should I service my AC living near the coast?
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.
What SEER rating do you recommend for coastal homes?
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.
Can you protect my existing AC from salt damage?
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.
