Brandon & Gamaliel
June 2026
A Dickinson homeowner reported that the unit was not cooling.
Brandon and Gamaliel found that both the 2nd floor unit and the 3rd floor unit were low on charge. They added 3 lbs of 410a refrigerant to the 2nd floor unit and 2.5 lbs of 410a to the 3rd floor unit, and checked the capacitor and contactor on each system.
The air delta on the 2nd floor unit went from 10° to 18°, and the 3rd floor unit went from 16 to 19.

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.
