AC Condensation Issues in Galveston

The Problem

A homeowner in Galveston noticed excessive condensation around their AC unit.

What We Found

Matthew discovered that the suction line in the compressor lacked proper insulation, leading to increased condensation.

The Fix

Matthew insulated the suction line in the compressor to help reduce the condensation. This involved carefully wrapping the line with insulation material to ensure it was adequately protected from temperature fluctuations.

The Result

The insulation effectively reduced the condensation, preventing potential water damage and improving system efficiency.

Pro Tip

If you notice excess condensation around your AC unit, it might be due to insufficient insulation. Insulating the suction line can prevent water damage and improve efficiency, saving you from costly repairs.

Why Did My AC Start Blowing Warm Air in Galveston?

The Problem

A homeowner in Galveston noticed that their air conditioning system was blowing warm air instead of cooling the house.

What We Found

Brandon discovered that the dual run capacitor was failing, which was preventing the AC unit from functioning properly.

The Fix

Brandon replaced the faulty dual run capacitor with a new AMRAD USA 370/440V model. This replacement restored the electrical efficiency of the AC system, allowing it to operate correctly.

The Result

After the capacitor replacement, the AC unit resumed blowing cold air, effectively cooling the home once again.

Pro Tip

A failing capacitor can cause your AC to blow warm air. If your system suddenly stops cooling, it might be time to check the capacitors; they are often a quick and cost-effective fix.

Aaron and Brandon are awesome and came to the rescue with our AC system thats not the normal brand type. They figured out the issue, very responsive and were generally just excellent. Will be joining their monthly plan as the AC systems really take a beating on the island, with the salty air and the multitude of power outages over the summer.

Local conditions

Why quality air conditioning 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

Air Conditioning in Galveston: questions answered

Answered by our licensed technicians serving Galveston.

How does salt air affect my air conditioning system?

Salt air accelerates corrosion on outdoor condenser units, refrigerant lines, and electrical connections. This can reduce system lifespan by 30-50% without proper coastal protection measures like marine-grade coatings and corrosion-resistant components.

How often should I service my AC living near the coast?

We recommend twice-yearly maintenance for coastal homes—once before summer and once after. The salt air and humidity demand more frequent filter changes and coil cleanings compared to inland properties.

What SEER rating do you recommend for coastal homes?

We typically recommend 16+ SEER2-rated systems for coastal properties. Higher efficiency units handle the constant humidity load better and save significantly on energy costs over their lifetime.

Can you protect my existing AC from salt damage?

Yes. We offer retrofit corrosion protection packages including condenser coil coatings, weatherproof electrical connections, and marine-grade cabinet treatments that extend the life of your current system.
