Herc Homes and River Humidity
The Mississippi river bottom keeps Herculaneum more humid than the rest of Jefferson County. That shows up as condensate problems, sweating ductwork in crawlspaces, and evaporator coils that need more frequent cleaning. We design and tune systems with that humidity in mind.
Signs You Need AC Repair in Herculaneum
- Vents blowing warm or room-temperature air
- Weak airflow even with the system running
- Short cycling (turns on and off rapidly)
- Energy bills climbing without a change in usage
- Rattling, hissing, or grinding noises
- Musty or burning odors when the AC runs
- Water pooling or ice forming around the unit
What We Check on an AC Service Call
- Refrigerant charge and leaks
- Capacitor and contactor
- Evaporator and condenser coils
- Condensate drain
- Filter and airflow

Most cooling failures trace back to one of these — we diagnose the real fault before quoting, so you're not paying for parts you don't need.
