Common Problems We Solve

Issues We Frequently Repair

  • Unusual noises from indoor or outdoor unit
  • Water leaking from the indoor unit
  • Remote or thermostat not controlling the system

Why These Problems Happen in Caseyville

Mini-splits run heavily in summer for cooling and in winter for heat. Hot, humid summers and cold snaps in Southern Illinois increase wear and can expose refrigerant leaks, sensor issues, or dirty coils. Regular maintenance and prompt repair help your system last and perform well.
