September 2026
A League City homeowner reported that their mini split was not cooling.
Christian and Matthew found that the outdoor fan would come on intermittently, and a check of the outdoor board revealed a small burn mark on it. They power cycled the unit multiple times, and twice the fan would not come on, causing the compressor to overheat and shut down.

A League City homeowner reported that the bathroom area felt like there was a lot of humidity.
Matthew found that the walls to the bathroom in the attic were open to the hot air in the attic. He sealed the wall openings with foam board and spray foam in the attic so hot air would no longer be able to drop down those walls and create that humidity.

After a hurricane or major storm, your first instinct is to get the AC running again. But turning on a damaged HVAC system can cause thousands in additional damage. Here's what to inspect first.
Read articleLeague City's rapid expansion has produced thousands of new homes with builder-grade HVAC systems. These are code-compliant but often not optimally sized or highest efficiency — upgrades can significantly improve comfort and reduce energy costs.
League City's proximity to Galveston Bay keeps humidity levels elevated year-round. Improperly maintained systems allow moisture to accumulate in ductwork, creating ideal conditions for mold growth that affects indoor air quality.
Homes near Clear Creek and Galveston Bay experience elevated salt and moisture in the air that can accelerate outdoor unit corrosion. Coastal-rated equipment and more frequent coil cleaning extend system life in these League City neighborhoods.
League City's summer heat indices regularly exceed 105°F, pushing AC systems to their limits for months at a time. Properly sized, high-efficiency equipment is critical to maintaining comfort without overwhelming energy bills.

A standard inland inspection checks refrigerant charge, electrical components, airflow, and mechanical operation. Our coastal inspection adds a full salt corrosion assessment (documenting corrosion stage at every metal surface), condensate and humidity evaluation (Gulf Coast systems produce two to four gallons of condensate daily), and storm damage assessment. An inspection that misses these coastal-specific items checks half the risks and ignores the half that actually kills equipment early.
Quarterly for ongoing maintenance inspections. We also recommend a full inspection after any tropical storm or hurricane that affects Galveston County, even if your home and equipment appear undamaged. Hidden storm damage is one of the leading causes of premature system failure on the Gulf Coast. Systems that have gone more than six months without professional evaluation should be inspected as soon as possible.
Stage 1 is surface oxidation: white powder on aluminum, green patina on copper, surface rust on steel. Cleaning and treatment can halt it entirely. Stage 2 is active pitting: salt has penetrated beyond the surface, creating pinholes in fins and pits at copper joints. Targeted repair stops the spread. Stage 3 is structural degradation: fins are perforated, joints leak, hardware fails. Major component replacement is typically necessary at this point.
Yes. Debris can bend condenser fins on back and side surfaces not visible from outside. Salt water that reached the outdoor unit corrodes electrical components, the compressor, and the fan motor even after water recedes. Storm surge can shift the condenser pad, causing refrigerant oil pooling and compressor strain. Power surges damage control boards and capacitors with failures that may not appear for weeks.
Our comprehensive coastal inspection is $129 and includes the full salt corrosion assessment, condensate and humidity evaluation, storm damage check, and standard system performance testing. You receive a written report with photographs documenting every finding and clear recommendations prioritized by urgency. Maintenance plan members receive this as part of their quarterly schedule.
