Aaron & Gabriel
August 2026
A homeowner in Galveston noticed that their home's insulation was not performing effectively, leading to increased energy bills and discomfort.
Aaron and Gabriel discovered that the spray polyurethane foam insulation was not properly protected, compromising its thermal efficiency.
To address the issue, Aaron and Gabriel applied a DC315 intumescent coating over the existing spray polyurethane foam. This specialized coating enhances the fire resistance of the insulation and ensures its durability over time.
The home's insulation was restored to optimal performance, improving energy efficiency and comfort.
If your insulation isn't performing well, it might need a protective coating. An intumescent coating can safeguard spray foam insulation, boosting its effectiveness and lifespan.

A homeowner in Galveston was experiencing excessive heat inside their metal building, making it uncomfortable to use during the summer.
Aaron and Gabriel found that the building's existing insulation was inadequate, allowing heat to penetrate and accumulate inside.
The technicians applied a hybrid spray foam insulation system, combining 1 inch of closed-cell foam with 3 inches of open-cell foam. This approach provided a robust barrier against heat transfer, significantly improving the building's thermal resistance.
The metal building was noticeably cooler and more comfortable, even during peak summer temperatures.
For metal buildings, a hybrid spray foam insulation system offers superior thermal resistance. Combining closed and open-cell foam can effectively manage heat transfer and improve comfort levels.

August 2026
A homeowner in Galveston was concerned about inconsistent cooling and suspected poor air quality in their home.
Aaron and Gabriel discovered that the HVAC system was underperforming due to clogged air filters and partially obstructed ductwork, which was affecting both cooling efficiency and air quality.
The team conducted a comprehensive HVAC performance audit, replaced the clogged air filters, and cleaned the ductwork to ensure unobstructed airflow. They also performed an air quality assessment to identify and address any lingering issues.
The homeowner experienced improved cooling efficiency and significantly better indoor air quality.
Clogged air filters can drastically reduce your HVAC system's performance and air quality. Replace filters every 1-3 months, especially during peak seasons, to keep your system running efficiently.
Adrian & Gamaliel
April 2026
A homeowner in Galveston noticed persistent dampness in their basement, leading to concerns about mold and air quality.
Adrian and Gamaliel discovered that the existing dehumidifier was undersized for the space, unable to effectively manage the humidity levels.
The team installed an Aprilaire 80-pint dehumidifier, which is specifically designed to handle larger areas and efficiently reduce moisture levels. They ensured the unit was properly calibrated and tested its operation to confirm optimal performance.
The new dehumidifier successfully reduced the humidity, creating a drier and healthier environment in the basement.
A dehumidifier that cycles on and off frequently might be too small for the space. Consider upgrading to a larger capacity unit to maintain consistent humidity levels and prevent mold growth.

Your AC is running, the temperature reads 74°F, but your home still feels damp and uncomfortable. Here's why standard air conditioning alone can't solve Gulf Coast humidity — and what actually works.
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.

Four factors stack on each other: sustained humidity above 80% fueling year-round mold growth, salt air from the Gulf infiltrating through every gap in the building envelope, post-hurricane moisture trapped in walls and flooring, and modern sealed construction that traps all of it inside. The EPA estimates indoor air can be 2-5x more polluted than outdoor air — in coastal humid climates, that multiplier is higher.
Not well enough for Galveston. Standard AC brings indoor humidity down to 60-65% on high-humidity days — still above the 45-50% range where mold growth slows dramatically. A whole-home dehumidifier integrated with your HVAC maintains proper levels regardless of outdoor conditions.
A layered approach works best: UV-C lights on the evaporator coil to prevent mold at the source, HEPA or electronic filtration to capture airborne particles including salt, and a whole-home dehumidifier if your AC can't maintain humidity below 55%. This addresses the specific threats — mold, salt, and humidity — that make coastal air quality worse.
Hidden mold is extremely common in Galveston homes. Colonies grow behind drywall, inside wall cavities, on the evaporator coil and drain pan, in ductwork joints, and under carpet padding — all locations you can't see. The spores circulate through your HVAC system every time the blower runs.
It can. Impact windows, spray foam, and weatherstripping reduce natural air exchange, trapping contaminants inside. An energy recovery ventilator (ERV) solves this — bringing in filtered fresh air while exhausting stale air and pre-conditioning incoming air to remove moisture.
