Common Mini-Split Problems We Fix

Mini-splits are reliable systems, but like any equipment, they can develop issues over time. Our technicians provide expert mini-split repair services to address the most common problems that impact performance and comfort:

  • Refrigerant leaks that cause weak or no cooling
  • Electrical issues preventing the system from turning on
  • Frozen coils that restrict airflow and efficiency
  • Faulty thermostats leading to uneven temperatures
  • Clogged filters or drainage problems causing water leaks
  • Unusual noises from motors, fans, or internal parts
