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.
Merrik
June 2026
The homeowner noticed their air conditioning unit was not cooling efficiently during a particularly hot day in Galveston.
Merrik discovered that the AC unit's condenser coils were covered in dirt and debris, which was hindering its cooling performance.
Merrik thoroughly cleaned the condenser coils, removing all dirt and debris. He also checked the refrigerant levels to ensure they were optimal and inspected the entire system for any other potential issues.
After the cleaning and inspection, the AC unit was able to cool the home efficiently, providing relief from the heat.
Dirty condenser coils can significantly reduce your AC's efficiency. During peak summer months, make sure to clean them every few weeks to maintain optimal 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!!

Even if your HVAC seemed fine after flooding, water damage shows up years later through corroded connections, contaminated ductwork, and weakened compressors. Here's what Friendswood and Galveston homeowners need to know.

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.
