Downstairs AC Not Cooling in a Two-System Galveston Home
What the customer reported
A Galveston homeowner in the 77550 area reported that the system was not cooling.
What we found and did
Brandon found the downstairs system under charged and full of green dye, while its capacitor checked out good. On the upstairs system, the refrigerant charge was adequate, but the dual run capacitor was out of spec by 20% on the herm and 53% on the fan. Brandon added R-410A refrigerant to the downstairs system.
Result
Both units measured a delta T of 18° or more.

Home AC Not Cooling in Early September in Galveston
What the customer reported
A Galveston homeowner in the 77551 area reported that their AC was not cooling.
What we found and did
Adrian found the system was low on refrigerant, with a small leak somewhere that he could not locate on this visit. He put in about 1 lb of R-410A refrigerant and added stop leak to the system.

Early September AC Not Working Well in a Galveston Home
What the customer reported
A Galveston homeowner in the 77550 area reported that their AC was not working well.
What we found and did
Christian and Matthew found that the system was low on gas and had a small leak, and they also found that the attic had no insulation at all. They added 3 pounds of 410A refrigerant along with stop leak to the system.
Result
The system was cooling well again with a temperature split of 18 degrees.

Rusting Part on Outdoor AC Unit in Galveston
What the customer reported
A Galveston homeowner in the 77551 area reported that the dryer was rusting on the outside of their AC system.
What we found and did
Adrian and Brandon found a rusted out leaking filter drier, a unit almost flat in charge, exposed low voltage control wires, and insulation baked off by the sun. They recovered the remaining refrigerant, cut out the old drier, and brazed in a new copper drier and a brass sight glass (for quick reference to the charge) while flowing nitrogen, then swept the system with nitrogen and pulled a vacuum from both sides down to below 500 microns. They weighed in approximately the system charge, added refrigerant to reach the required levels both high and low, and commissioned the system. They also replaced the damaged section of thermostat wire, replaced the damaged sections of insulation, and wrapped the rest with UV resistant lineset tape.
Result
The system held a pressure test at 275 psi for 25 minutes to verify it was tight, and all electrical components and connections were checked and found tight and within rated specs.
Why quality refrigerant services 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.

Refrigerant Services in Galveston: questions answered
Answered by our licensed technicians serving Galveston.
Why is my AC blowing warm air if it's not low on refrigerant?
Salt corrosion on condenser coils can reduce heat transfer enough that your system runs continuously without reaching set temperature, even with a full refrigerant charge. If the aluminum fins are pitted, caked with salt deposits, or crumbling, the coil can't reject heat efficiently regardless of refrigerant level.
How do you find refrigerant leaks that other companies can't?
We use three methods: electronic leak detectors that sense concentrations as low as 0.1 oz/year, nitrogen pressure testing at 300-400 PSI to isolate which section is compromised, and UV dye injection for microscopic leaks. Most companies only use one method. We use all three because coastal pinhole leaks are harder to find.
Should I just top off my refrigerant?
No. Adding refrigerant without fixing the leak is like putting air in a tire with a nail. On the coast, the salt corrosion that caused the first leak is actively creating new ones. You'll need another recharge in weeks or months, at $50-$150/lb for R-410A or $150-$300/lb for R-22.
My system uses R-22. What are my options?
R-22 is phased out and increasingly expensive. If your system needs refrigerant more than once per season, replacement with a new R-410A or R-454B system is the better investment. Two R-22 recharges can cost $1,500-$6,000, money that goes further toward new equipment.
Can corroded copper refrigerant lines be repaired or do they need full replacement?
Isolated leaks can be brazed with silver solder and coated. But on coastal systems over 7-8 years old, we often find multiple corroded areas. Repairing three spots only to have new leaks open in six months isn't cost-effective. Full line replacement with corrosion-protected tubing is the smarter investment.
