Adrian
August 2026
An AC unit in a Galveston home was not cooling effectively, leading to discomfort on a warm day.
Adrian discovered that the issue was related to clogged filters and potentially blocked drainlines.
Adrian replaced the clogged filters and thoroughly checked the drainlines for any blockages. Ensuring both components were clear, he restored the unit's normal function.
The AC unit resumed proper cooling, providing the homeowner with much-needed relief from the heat.
Dirty filters can significantly reduce your AC's efficiency. Replace them every 1-3 months to maintain optimal airflow and prevent drainage issues.
Matthew
August 2026
The homeowner noticed that their attic was unusually warm, making the rest of the house uncomfortable.
Matthew discovered that the attic door was not properly insulated, allowing heat to seep into the living spaces.
Matthew installed an attic door tent to improve insulation and prevent heat from entering the home through the attic access. This simple yet effective solution helped maintain a more consistent temperature throughout the house.
The installation of the attic door tent resulted in a cooler and more comfortable home environment.
An attic door tent can significantly reduce heat transfer from your attic. If your home feels warmer than usual, especially in upper floors, consider installing one to improve energy efficiency.
Adrian
August 2026
A commercial property in Galveston was experiencing issues with their HVAC system, causing concern about potential water damage.
Adrian discovered that the secondary float switch was malfunctioning, which could lead to overflow and damage.
Adrian carefully inspected the secondary float switch and identified a blockage that was preventing it from functioning properly. He cleared the obstruction and tested the switch to ensure it was operational and could effectively prevent overflow.
With the float switch functioning correctly, the risk of water damage was mitigated, and the HVAC system was back to normal operation.
If your HVAC system has a secondary float switch, ensure the drain lines are clear of debris. A blocked line can prevent the switch from activating, risking overflow and potential water damage.
Merrik
June 2026
A homeowner in the 77554 area noticed their AC wasn't cooling efficiently during a routine check.
Merrik found that the system's filters were clogged with dust and debris, restricting airflow.
Merrik performed a thorough cleaning of the AC unit, including replacing the clogged filters and checking the refrigerant levels to ensure optimal performance. He also inspected the condenser coils and cleared any obstructions to improve efficiency.
The AC system was restored to full efficiency, providing consistent cooling throughout the home.
Clogged filters can significantly reduce your AC's efficiency. Replace filters every 1-3 months, especially during peak cooling seasons, to maintain optimal airflow and system performance.
Excellent communication on arrival time and condition of unit as well as planning for future maintenance needs of the unit! Excellent spring service tune up!!

Salt air, extreme humidity, and storm exposure shorten HVAC lifespans by 3-5 years on the Gulf Coast. Here's what Galveston homeowners can do to fight back.
Read articleGalveston 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.
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.
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.
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.

Answered by our licensed technicians serving Galveston.
In Galveston, we recommend twice-yearly maintenance: once in spring before AC season and once in fall before heating season. However, the salt air means condenser coil cleaning should happen quarterly for units within a mile of the beach to prevent corrosion buildup.
Coastal HVAC maintenance includes anti-corrosion coil treatment, salt residue cleaning, condensate drain flush (critical in our humidity), electrical connection inspection for salt damage, and hurricane preparedness checks. These steps can double the lifespan of your Galveston HVAC system.
Yes, our Coastal Protection Plan is designed specifically for island properties. It includes bi-annual tune-ups, priority scheduling during summer emergencies, quarterly coil cleanings, and a corrosion warranty — all essential for Galveston systems exposed to salt air year-round.
