Ellisville Homes and Bonus-Room Comfort
Ellisville's 1990s two-stories with bonus rooms over the garage almost universally complain about that bonus room being unusable in summer. The fix is usually a small zoning damper or a single-zone mini-split — not a bigger main AC.
Signs You Need AC Repair in Ellisville
- 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

- Electrical connections
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.
