Professional Boiler Services in League City, TX

Boilers are uncommon in Galveston — but they aren't unheard of. A handful of older island homes still run hot water boiler systems that predate the shift to forced-air heating, and some newer builds and renovations have brought in hydronic radiant floor setups that rely on boiler units. If you have one, you already know: finding someone who actually works on boilers in Galveston County isn't easy. Coastal Eco Heating & Air services, repairs, and installs boiler systems across the island and into Texas City, League City, Dickinson, La Marque, and Santa Fe.

Why Boilers Take Extra Abuse on the Gulf Coast

Salt air is the single biggest threat to any mechanical system on Galveston Island. Boiler components — heat exchangers, circulator pumps, expansion tanks, zone valves — all contain metal parts that corrode faster in a coastal environment. Inland, a well-maintained boiler might last 20 to 30 years. On the island, without corrosion-resistant components and regular maintenance, you can lose five to ten years off that lifespan.

The other factor is idle time. Galveston's heating season runs roughly December through February, with a few cold snaps sneaking into November and March. That means your boiler sits unused for roughly nine months of the year. During those nine months, salt-laden humidity works its way into every connection, fitting, and electrical component. When you fire it up on the first cold night, you find out what corroded while you weren't looking.

Boiler Maintenance for Coastal Homes

Our $129 tune-up (reg. $225) applies to boiler systems just like it does to any heating equipment. For boilers specifically, that inspection covers the heat exchanger for cracks or corrosion, circulator pump operation, expansion tank pressure, thermostat calibration, and a full check of all zone valves and piping connections. We also inspect the flue and venting system, test safety controls, and check water pressure and temperature settings.

For coastal installs, we go further. We inspect electrical connections and relay contacts for salt corrosion, check for signs of moisture intrusion around the unit, and recommend protective coatings or replacements where corrosion has started to compromise components.

Boiler Repair on the Island

The most common boiler problems we see in Galveston are corroded circulator pumps, failed zone valves, leaking expansion tanks, and thermostat or control board failures tied to moisture and salt damage. When a boiler stops producing heat or starts making banging and knocking sounds — kettling — the cause is almost always tied to sediment buildup, a failing pump, or a waterlogged expansion tank.

We carry common boiler parts and can diagnose most issues on the first visit. For older systems where parts are harder to source, we'll give you honest options: repair if it makes sense, replace if it doesn't.

Should You Install a Boiler in Galveston?

If you're building new or doing a major renovation and considering radiant floor heating, a boiler is the way to power it. Modern condensing boilers are efficient — 95%+ AFUE — and pair perfectly with hydronic radiant systems. The key in Galveston is using corrosion-resistant materials from the start: stainless steel heat exchangers, marine-grade electrical connections, and properly sealed venting.

For whole-home heating, a heat pump is usually the more practical choice for the Gulf Coast climate. But for targeted radiant installs — master bathrooms, kitchens, sunrooms — a small boiler setup can be a smart addition to a home. We provide free estimates on all new boiler installations, and every coastal install uses corrosion-rated components designed for the salt air environment.
