A San Leon homeowner reported that their mini split was not cooling.
Adrian found a bad outdoor fan motor, a bad indoor temperature sensor, and a bad indoor board, and the system was also low on refrigerant. He replaced the outdoor fan motor, the indoor board, and the temperature sensors. He then pulled the factory charge and recharged the system with the correct amount of refrigerant, adding 2 pounds.

Answered by our licensed technicians serving San Leon.
Salt air corrodes copper refrigerant lines, creating pinhole leaks that let refrigerant escape slowly over weeks or months. This is the most common AC repair issue on the Gulf Coast. Topping off refrigerant without finding and fixing the leak is temporary: the corrosion is ongoing and will create new leak points.
We provide same-day and 24/7 emergency AC repair across Galveston, Texas City, League City, Dickinson, La Marque, and Santa Fe. Our trucks carry the parts that fail most often in coastal systems (capacitors, contactors, and fan motors), so most repairs are completed in one visit.
In Galveston, the most likely cause is salt buildup on your condenser coils reducing heat transfer efficiency. Your system runs constantly but can't reject heat effectively. Heavy corrosion requires coil cleaning or replacement with a marine-grade coated unit. Low refrigerant from corroded lines is the second most common cause.
For coastal systems, we use a straightforward guideline: if the repair exceeds 40% of a new system's cost and the unit is over 8 years old, replacement usually makes more financial sense. An 8-year-old system in Galveston has the equivalent wear of a 12-year-old system in Dallas due to salt exposure and extended run times.
Power surges during tropical storms and thunderstorms commonly blow capacitors and can damage compressor windings. Check your breaker panel first: a tripped breaker is the simplest fix. If the breaker holds but the system won't start, a blown capacitor is the most likely culprit. We carry replacements on every truck.
