Possible Causes

Thermostat located near supply vent or heat source, Oversized Luxaire AC, Low refrigerant charge, Faulty high‑ or low‑pressure switch

How to Fix / Troubleshooting

Safety: Most checks are low‑risk but avoid opening refrigerant circuits.

  • Check thermostat placement: Ensure the thermostat is not directly in the path of a supply register, in direct sunlight, or near appliances. Relocation may be needed.
  • Verify filter and coils: Replace dirty filters and clean coils to ensure stable operation.
  • Observe outdoor unit: Watch the Luxaire condenser during operation. If it shuts off quickly while the indoor blower continues, a safety switch may be tripping. Call a technician to check pressures and switches.
  • Consider system sizing: If the home cools very quickly but humidity remains high, the system may be oversized. Discuss options with an HVAC professional.
