Salt on three sides
San Leon homes face salt-laden air from three directions. There's nowhere to hide. Standard equipment fails fast. We default to the same coastal-rated coils we run on Galveston West End: factory coatings, stainless hardware, marine-grade housings. The install cost adds 15 to 20 percent. The replacement cycle drops from 6 years to 12 plus.
Top repairs we run in San Leon
Outdoor coil corrosion is the dominant diagnostic finding. The peninsula geometry means salt deposits accumulate from multiple wind directions, so even a unit that's tucked behind the house gets exposure. Salt-pitted contactors run a close second, they fail at the contact points where the silver coating has worn through. Capacitors fail at roughly twice the inland rate ($180 to $320 each). Refrigerant work at weathered fittings runs $350 to $650 for diagnosis and R-410A recharge. Indoor coil corrosion comes up regularly on systems where the cabinet wasn't sealed against the salt air leaking in through the suction line entry.
Fishing cottages to modern raised builds
San Leon has every kind of bay home: 1950s fishing cottages with original window units, 1980s bayfront ranch with original air handlers, raised post-Ike rebuilds with modern equipment. We work them all. When a system reaches a decision point, we quote both repair and replacement with the trade-offs in writing and the customer chooses.
