Reinstalled Heat Pump Would Not Turn Back On in Galveston

What the customer reported

A Galveston homeowner reported that the unit would not come back on after it was reinstalled by another company, and that company could not figure out how to get it running.

What we found and did

Brandon and Gabriel found the unit off on a low pressure code, with leaks on both flare connections, multiple kinks in the newly added lineset, control wiring wired improperly (disabling the heat pump functionality), loose high voltage connections, improper flexible conduit connections, no ground wiring in the disconnect feeding the outdoor unit, and signs that the unit had been disassembled and improperly reassembled, allowing water to get to the electrical components. They repaired the refrigerant leaks, pressure tested the system, and vacuumed it down to 416 microns isolated. They then measured the lineset length and weighed in refrigerant based on lineset length plus factory charge. Finally, they rewired the communication wiring inside and outside and set the dipswitch settings back to the original configuration from the initial install.

Result

The unit fired up and runs as expected.

Leaking, Noisy AC Stopped Working in Galveston

What the customer reported

A Galveston homeowner in the 77554 area reported the unit leaking, the unit not working, and the unit making noise.

What we found and did

Across three visits, Brandon and Merrik found drain lines improperly configured, causing standing water in the air handler's internal drain pan and frequent backups leading to water damage, along with a melted common wire on the contactor outside and a bad fan motor. They chemically flushed the existing drain lines, vacuumed and flushed the internal drain pan, removed the improperly installed p traps, and installed a new smooth p trap with a ball valve and a float switch on the secondary drain to shut the system down if a backup occurs. They also replaced the heavily corroded contactor, repaired the common wire to restore operation, and replaced the fan motor.

Result

The capacitor and refrigerant charge both checked out within spec, and the system performs as expected.

AC Unit Freezing Up in Spring in Galveston

What the customer reported

A Galveston homeowner in the 77550 area reported that their unit was freezing up.

What we found and did

Merrik found that the condenser was low on refrigerant and the capacitor was bad. He put more 410-A refrigerant in the system and changed out the dual run capacitor.

Local conditions

Why quality furnace repair matters in Galveston

Salt Air Corrosion

Galveston Island's direct ocean exposure means HVAC outdoor units face constant salt spray that corrodes condenser coils, electrical connections, and cabinet panels far faster than inland locations. Coastal-rated equipment and frequent cleaning are essential.

Extreme Humidity

Galveston's humidity regularly exceeds 80%, forcing AC systems to handle heavy moisture removal alongside cooling. Without proper dehumidification, homes experience clammy air, mold growth, and premature equipment wear.

Hurricane & Storm Exposure

Galveston's island location makes HVAC systems vulnerable to hurricane-force winds, storm surge, and power surges. Proper equipment anchoring, surge protection, and post-storm inspections are critical for system longevity.

Year-Round Cooling Demand

Galveston's mild winters and long, hot summers mean AC systems run 8-9 months per year — significantly more than inland areas. This extended runtime accelerates wear on compressors, fans, and electrical components, making proactive maintenance essential.

FAQ

Furnace Repair in Galveston: questions answered

Answered by our licensed technicians serving Galveston.

Why is my furnace blowing cold air?

The most common causes in Galveston are a failed sequencer (electric furnaces) or a failed igniter or flame sensor (gas furnaces). In electric furnaces, sequencers stage heating elements on in sequence. If the first-stage sequencer fails from salt corrosion, no elements activate and the blower pushes unheated air. In gas furnaces, a cracked igniter or corroded flame sensor prevents the burner from lighting or staying lit.

Is a burning smell when I first turn on my furnace normal?

Usually, yes. After sitting idle for nine months in Galveston humidity, dust settles on heating elements. The first time they heat up, that dust burns off and produces a brief burning smell. It should clear within 30 minutes to an hour. If the smell persists, smells like melting plastic or rubber, or is accompanied by visible smoke, turn the system off and call for service. Those indicate an electrical or component problem.

Should I repair or replace my furnace?

If the furnace is under 15 years old and needs a single component replaced, repair usually makes sense. Common repairs run $100-$600 depending on the part. If the furnace is over 15-20 years old, has multiple failed components, or shows significant corrosion damage, replacement is usually the better investment. A new electric furnace runs $1,500-$3,500, and you should also consider a heat pump conversion for Galveston mild climate.

How long does a furnace repair take?

Most furnace repairs are completed in a single visit, typically within one to two hours. Our trucks carry the components that fail most often in coastal environments: sequencers, heating elements, capacitors, igniters, flame sensors, and control boards. For less common parts, we may need to order and return for a second visit, but we will give you a clear timeline upfront.

Why does my furnace keep shutting off after running for a few seconds?

For gas furnaces, this is almost always a corroded flame sensor. The sensor cannot detect the flame properly due to salt-air oxidation, so the gas valve shuts down as a safety measure. For electric furnaces, a clogged filter or failed blower motor can cause the high-limit safety switch to trip, shutting the system down to prevent overheating. Both are common and repairable issues.
