An AC unit in Galveston was not cooling properly during a particularly hot day.
Brandon Kerr identified that the issue was with the 2-ton single stage Luxaire condenser.
Brandon replaced the malfunctioning 2-ton single stage Luxaire condenser to restore the cooling function of the system. This involved removing the faulty unit and installing a new condenser, ensuring all connections were secure and the system was properly charged.
The AC system was restored to full functionality, providing the homeowner with reliable cooling once again.
A malfunctioning condenser can cause your AC to stop cooling effectively. If your AC isn't cooling, consider having a professional inspect the condenser to avoid more costly repairs down the line.

League City's rapid growth means thousands of homes have builder-installed HVAC systems. Here's what "builder grade" really means, why it may not be enough for Gulf Coast extremes, and when upgrading makes financial sense.
Read articleGalveston 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.

If repair cost exceeds 40% of a new system's price and the unit is over 8 years old, replacement usually makes more sense. Coastal systems age faster — an 8-year-old unit in Galveston has the equivalent wear of a 12-year-old system in Dallas due to salt exposure and extended run times.
Replacement costs range from $5,500 to $14,000 depending on system size, efficiency rating, and coastal protection level. Variable-speed systems cost more upfront but deliver significantly better humidity control and lower operating costs over our 9-10 month cooling season.
If your R-22 system needs refrigerant more than once per season, yes. R-22 is phased out and costs $150-$300 per pound. Coastal systems leak refrigerant more frequently due to salt-corroded copper lines. Two recharges can cost $1,500-$6,000 — money better spent toward a new system running R-410A.
Yes, if properly sized and configured. We recommend variable-speed or two-stage systems for the coast. They run longer at lower capacity, pulling far more moisture from the air than single-stage units. You'll feel comfortable at 76 instead of cranking to 72 and still feeling clammy.
Straightforward replacements complete in one day. Jobs requiring ductwork sealing, new line sets, or electrical upgrades take two days. We inspect and seal existing ductwork during every replacement — leaky ducts in Gulf Coast attics pull in hot, humid air that reduces efficiency by 15-25%.
