Heater Stopped Working in Galveston? Here's What to Do.

Galveston cold snaps don't happen often, but when they do, they catch people off guard. The Gulf Coast doesn't get the sustained deep freezes that North Texas or the Hill Country deal with, so many island homes have heating systems that haven't been tested in months — or heating that was never designed for a real cold event. When a norther blows through and the temperature drops into the 30s with 25 mph wind off the water, a 40-degree reading feels like it's in the low 20s. That's when phones start ringing. Coastal Eco Heating & Air provides 24/7 emergency heat repair across Galveston Island, Texas City, League City, Dickinson, La Marque, and Santa Fe.

Why Galveston Heating Emergencies Are Different

Most of the country expects winter. Galveston doesn't. That changes everything about how heating emergencies play out here. Homeowners go nine or ten months without touching their thermostat. When the first real cold front hits — usually late November or December — systems that sat idle through a humid, salt-air summer are expected to fire up instantly. Many don't.

The Gulf wind chill factor is the other piece. Galveston sits on a barrier island with nothing between your home and the open Gulf. A 40-degree night with 20 mph sustained wind puts the wind chill around 30 degrees. Older island homes with single-pane windows, pier-and-beam foundations, and minimal insulation lose heat fast. Pipes in crawl spaces and exterior walls are at risk of freezing — especially on the bay side where wind exposure is worst.

What to Do When Your Heater Stops Working

First, check the obvious: thermostat set to heat, breaker not tripped, filter not completely clogged. These three things account for about 30% of emergency calls. If the system is getting power and the thermostat is calling for heat but nothing happens — no fan, no warm air, no sounds at all — you're dealing with a component failure that needs a technician.

If your heat pump is running but only blowing cool air, it may be stuck in cooling mode (a reversing valve issue) or the auxiliary heat strips aren't engaging. Electric furnaces that blow room-temperature air usually have a failed sequencer or burned-out heating element.

Call Coastal Eco at (409) 599-1948. We respond same-night for emergency heating calls. Our trucks carry the most common coastal failure parts — corroded relays, sequencers, capacitors, and control boards — because we know exactly what salt air does to heating systems that sit idle for nine months.

Frozen Pipe Prevention During Cold Snaps

When temperatures drop below freezing, island homes with pier-and-beam construction are at highest risk. Exposed pipes under the house and in exterior walls can freeze in hours. If your heating system fails during a freeze event, open cabinet doors under sinks, let faucets drip, and use safe supplemental heat while waiting for repair. Do not use propane heaters, charcoal, or ovens for heat — Galveston fire departments respond to carbon monoxide calls every cold snap.

The Coastal Corrosion Factor

Emergency heating failures on the island almost always trace back to corrosion. Relays and contactors develop salt deposits on their contact points. Sequencers — the components that stage electric heating elements on in sequence — corrode internally and fail to close. Control boards develop micro-corrosion on circuit traces. These are the parts that fail when you need heat the most, because they've been quietly degrading in humid salt air all year.

Coastal Eco stocks corrosion-resistant replacement parts and uses marine-grade electrical connections on all repairs. When we fix your system during an emergency, we're also building it to resist the next nine months of coastal exposure.

Don't Wait for the Emergency

The best way to avoid a midnight heating call is a $129 tune-up (reg. $225) in November, before the first cold front. We'll catch corroded components, test every heating stage, and verify your system is ready. But when emergencies happen, we're here — 24/7, across Galveston County. Call (409) 599-1948.

Problems We Fix

Our experts can diagnose and resolve any issue

Corroded Relay and Contactor Points

Salt deposits build on electrical contact points during months of idle time, preventing relays and contactors from making a solid connection when the thermostat calls for heat. The system appears dead — no fan, no warm air, no response — even though it has power.

Failed Sequencers in Electric Furnaces

Sequencers stage heating elements on in sequence to avoid overloading the circuit. Salt corrosion causes them to stick open, meaning one or more elements never activate. The furnace blows air but it is lukewarm or cold — especially dangerous during a freeze event.

Heat Pump Stuck in Cooling Mode

The reversing valve switches a heat pump between heating and cooling. When it fails or sticks, the system blows cool air when it should be heating. This is one of the most common emergency calls during Galveston cold snaps — the system runs but provides no warmth.

Blown Capacitor

Capacitors store the electrical charge needed to start the compressor and fan motors. Gulf Coast heat and humidity degrade capacitors faster than dry climates. A failed capacitor means the outdoor unit hums but will not start, leaving you without heat pump heating capability.

Control Board Micro-Corrosion

Electronic control boards develop salt corrosion on circuit traces during humid Gulf Coast summers. The board may work intermittently — the system starts and stops randomly — or fail completely. This damage is often not visible without close inspection of the board surface.

Auxiliary Heat Strip Failure

Heat pumps use electric heat strips as backup during the coldest temperatures. If these strips fail from corrosion or burned-out elements, the heat pump alone cannot keep up when temperatures drop into the 30s with Gulf wind chill, leaving the home dangerously cold.

Coastal Failure Parts Stocked on Every Truck

Our trucks carry the components that fail most often in salt-air environments — corroded relays, sequencers, capacitors, contactors, and control boards. We know exactly what Galveston climate does to heating systems, so we stock for it. Most emergency repairs are completed on the first visit.

Marine-Grade Emergency Repairs

When we replace a failed component during an emergency, we use corrosion-resistant parts and marine-grade electrical connections. We are not just getting you through tonight — we are building the repair to resist the next nine months of coastal exposure so the same part does not fail again next winter.

Frozen Pipe Prevention Guidance

Galveston pier-and-beam homes with exposed pipes are at serious risk during freeze events. Beyond fixing your heat, we advise on immediate pipe protection steps and can recommend permanent solutions to prevent freeze damage in future cold snaps.

Frequently Asked Questions About Emergency Heat Repair

Get answers to common questions about our emergency heat repair services

Do you offer 24/7 emergency heating repair in Galveston?

Yes. Coastal Eco Heating and Air provides 24/7 emergency heat repair across Galveston Island, Texas City, League City, Dickinson, La Marque, and Santa Fe. We respond same-night for emergency heating calls during cold snaps. Call (409) 599-1948 any time your heat goes out.

What should I check before calling for emergency heat repair?

Check three things first: Is the thermostat set to heat mode and set above the current room temperature? Is the circuit breaker for the furnace or heat pump tripped? Is the air filter completely clogged? These account for about 30% of emergency calls and cost nothing to fix. If those check out and you still have no heat, call us.

Why do heating systems fail during the first cold snap in Galveston?

Your heating system sits idle for nine to ten months in Galveston climate. During that time, salt-laden humidity corrodes relays, contactors, sequencers, and control board circuits. Components that worked fine last winter quietly degrade all summer. When the first cold front hits and the system is asked to perform, these weakened parts fail. A pre-season tune-up in November catches these problems before they become emergencies.

What should I do about my pipes if my heater fails during a freeze?

Open cabinet doors under sinks to let warm air reach pipes, let faucets drip to prevent standing water from freezing, and use safe supplemental heat sources. Do not use propane heaters, charcoal, or ovens for heat — Galveston fire departments respond to carbon monoxide calls every cold snap. Island homes with pier-and-beam construction and exposed pipes are at highest risk.

How much does emergency heating repair cost?

Emergency repair costs depend on the failed component. Most common failures — corroded relays, sequencers, capacitors, and control boards — run $100 to $400 for parts and labor. Our trucks carry the components that fail most often in coastal environments, so most repairs are completed in a single visit without the markup of ordering parts after diagnosis.
