Why Is My Mini Split Not Cooling?
One of the most common service calls we receive is “why is my mini split not cooling?” This issue can be caused by several factors, including:
- Low or leaking refrigerant
- Dirty evaporator or condenser coils
- Compressor performance issues
- Faulty temperature sensors
- Blocked airflow or fan problems
If your mini split is blowing warm air, continuing to run the system can worsen the damage. Professional diagnostics are essential to identify the exact cause and prevent costly breakdowns.

- Clogged or disconnected condensate drain lines

Mini Split Not Heating? Troubleshooting & Repair
If your system is running but not producing heat, mini split not heating troubleshooting is required. Common causes include:
- Reversing valve failure
- Refrigerant level imbalance
- Defrost cycle malfunctions
- Outdoor unit sensor issues
- Electrical control failures
Our ductless mini split repair technicians restore proper heating performance while ensuring your system operates safely and efficiently during cooler months.
Mini Split Compressor Repair
The compressor is the heart of your ductless system. When it fails, cooling and heating performance drop dramatically. Mini split compressor repair may be necessary if you notice:
- System not maintaining temperature
- Loud or unusual noises from the outdoor unit
- Tripped breakers or startup failures
- Reduced efficiency and long run times
We evaluate whether repair or replacement is the most cost-effective solution based on system age and condition.
Mini Split Fan Not Working
If the fan stops working, airflow is compromised and the system may shut down to protect itself. Mini split fan not working issues are commonly caused by:
- Failed fan motors
- Capacitor problems
- Electrical wiring faults
- Control board errors
Fast repair helps prevent overheating and secondary system damage.
Mini Split Making Noise Repair
Ductless systems are designed to run quietly. If you hear rattling, buzzing, grinding, or clicking, mini split making noise repair should be scheduled immediately. Noises may indicate:
- Loose mounting hardware
- Fan blade imbalance
- Motor bearing wear
- Compressor strain
Ignoring abnormal sounds can lead to more expensive repairs later.
Refrigerant Leak Mini Split Repair
Low refrigerant levels significantly reduce system performance. Refrigerant leak mini split repair requires EPA-certified handling and precise leak detection. Signs include:
- Weak cooling or heating
- Ice buildup on coils
- Hissing sounds
- Higher energy bills
We locate the leak, repair the damaged section, and recharge the system to manufacturer specifications.
