Professional Refrigerant Services in San Jacinto, Galveston

Standard air conditioning equipment takes a beating on the Gulf Coast. Salt air off the Gulf corrodes coils, contactors, and electrical connections three to five times faster than inland systems. Add 95-degree heat with 80-plus percent humidity from May through October, and your AC is working harder than almost any system in Texas. A system that ran fine in Houston or Dallas will quit years early out here — often on the hottest day of the year.

That's why Coastal Eco Heating & Air builds every service around what the coast actually demands. Our $129 tune-up (regularly $225) includes a full corrosion inspection — checking coil fins, drain lines, refrigerant connections, and electrical components for salt damage before it turns into a breakdown. That single visit is the difference between a system that survives Galveston summers and one that leaves you stranded. We run 24/7 emergency service because we know a dead AC in Galveston isn't an inconvenience. It's a health risk.

What Falls Under Air Conditioning Service

This category covers everything that keeps your home cool and dry. AC repair for any brand or system type. New installations using corrosion-resistant equipment rated for coastal environments. Seasonal tune-ups that catch salt damage early. Refrigerant checks and recharges. Thermostat diagnostics. Ductwork evaluation. Emergency service when your system fails at 2 AM in August.

We work on central air systems, ductless mini-splits, heat pumps running in cooling mode, and packaged units. If your home on Galveston Island has an older system with no ductwork, we have options for that too. If you're in League City or Dickinson with a two-story home that can't keep the upstairs cool, we can diagnose whether it's a capacity issue, duct problem, or something else entirely.

Why Coastal AC Service Is Different

Inland HVAC companies use standard parts and call it done. On the Gulf Coast, that approach cuts your system's life in half. We spec corrosion-resistant condenser coils, use marine-grade fasteners, and apply protective coatings on outdoor units exposed to salt-laden wind. Every installation accounts for hurricane season — elevated equipment where flooding risk exists, secure mounting to handle high winds from June through November, and surge protection for the power spikes that follow storms in the CenterPoint Energy service area.

Humidity control matters just as much as temperature out here. An AC system that cools but doesn't dehumidify properly leads to mold, musty air, and moisture damage inside walls. We size systems and configure settings specifically for the moisture loads that come with living near the water — whether you're on the Strand District, the seawall, or a few miles inland in La Marque or Santa Fe.

Serving Galveston County and the Surrounding Coast

We service homes and businesses across Galveston Island, Texas City, League City, Dickinson, La Marque, and Santa Fe. From historic Strand District buildings with unique cooling challenges to newer construction in League City subdivisions, we know the equipment and approaches that hold up in this climate. Our technicians live and work on the coast. They understand what salt air does to HVAC equipment because they see it every single day.

If your AC is running constantly, blowing warm air, cycling on and off, or just not keeping up with Gulf Coast humidity — call us. Same-day service is available, and emergency calls are answered around the clock.
