Professional Emergency AC Repair in Galveston, TX

When your AC stops working in Galveston during summer, it's not an inconvenience — it's a safety issue. Heat index on the island regularly exceeds 110 degrees from June through September. Indoor temperatures without air conditioning climb into the 90s within hours. Elderly residents, young children, and anyone with respiratory conditions face immediate health risks. This isn't a situation where you can "tough it out" until Monday morning or wait three days for a scheduled appointment.

Before You Call: Quick Checks That Might Save a Service Call

Before picking up the phone, run through these quick troubleshooting steps. About 15% of our emergency calls turn out to be something the homeowner could have fixed in five minutes.

Check your thermostat. Make sure it's set to "cool" and the temperature is set below the current room temperature. Check the batteries if it's a battery-powered model. A dead thermostat battery is one of the most common "my AC stopped working" calls we get.

Check your breaker panel. Look for a tripped breaker in your electrical panel. Power surges — common during tropical storms and summer thunderstorms — trip breakers protecting your AC system. If the breaker is tripped, flip it fully to "off" and then back to "on." If it trips again immediately, leave it off and call us — you likely have an electrical fault that needs professional diagnosis.

Check your air filter. A completely clogged filter can restrict airflow enough to freeze the evaporator coil, which triggers a safety shutdown. If your filter is solid gray or you can't see light through it, replace it and give the system 2-3 hours with the fan running (but cooling off) to thaw.

Check the condensate drain pan. If your air handler has a secondary drain pan with a float switch, a clogged condensate drain will trigger the switch and shut the system down to prevent water damage. You might see standing water in the drain pan. This is a safety feature, not a malfunction — but the drain needs clearing before the system will run again.

Common Emergency Failures in Coastal Systems

If those checks don't solve it, here's what our technicians most commonly find on emergency calls in Galveston:

Blown capacitors from power surges. Tropical storms and summer thunderstorms cause power fluctuations that destroy capacitors. You might hear a humming or clicking from the outdoor unit, or the fan might spin but the compressor won't engage. This is the most frequent emergency repair during storm season — and the most straightforward to fix. We carry common capacitor sizes on every truck.

Compressor failure from salt corrosion. Years of salt exposure corrode condenser coils, forcing the compressor to work progressively harder. Eventually it overheats and fails. A locked or grounded compressor is typically the most expensive emergency repair. If the system is over 8 years old and the compressor fails, we'll give you an honest comparison of repair cost versus replacement cost before proceeding.

Refrigerant loss from corroded lines. Salt-pitted copper refrigerant lines develop leaks that can go from "slowly losing charge" to "completely empty" during a single hot stretch. The system blows warm air, ices up, or shuts down on high-pressure protection. We locate the leak, assess whether a spot repair or full line replacement makes sense, and recharge the system.

Flooded condensate drain. In Galveston's humidity, your AC pulls out gallons of water per day. That water drains through a PVC line that algae, mold, and debris can clog rapidly in our climate. A clogged drain backs water into the system and triggers a safety shutdown — or worse, overflows and causes water damage to ceilings and walls below.

Contactor failure. The contactor is the relay that sends power to the compressor and fan motor. Salt air corrodes contactor points, causing them to pit, weld shut, or fail to make contact. A pitted contactor can cause the outdoor unit to run continuously (even when the thermostat isn't calling for cooling) or not start at all.

What to Expect When You Call

We answer emergency calls 24/7 — nights, weekends, and holidays. Our dispatcher will walk you through the quick checks above if you haven't already tried them. If you need a technician, we provide an estimated arrival window. Our trucks are stocked with the parts that fail most commonly in coastal systems, so the majority of emergency repairs are completed in a single visit.

Protecting Your Family While You Wait

If your AC is down and help is on the way, take these steps to stay safe in Gulf Coast heat: close blinds and curtains on sun-facing windows, use fans to circulate air, move to the lowest level of your home (heat rises), drink water continuously, and check on elderly neighbors — many older Galveston Island residents live alone and may not recognize heat exhaustion symptoms.

If anyone shows signs of heat stroke — hot red skin, confusion, rapid pulse, or loss of consciousness — call 911 immediately. This is a medical emergency that Galveston's heat makes all too real.
