Problem: The Ductless Mini Split System Won’t Turn On
If your ductless mini-split system fails to turn on, the initial step is to examine the power source. Ensure the system is properly plugged in and the power outlet functions correctly. Examine the remote control if the power source is not the problem’s root. If the remote control is not working as expected, it may need new batteries or a reset. If the remote control is functioning correctly, the next step is to check the circuit breaker to see if it has tripped.

Problem: The Ductless Mini Split System Is Blowing Hot Air Instead of Cold Air
If your ductless mini-split system is blowing hot air instead of cold air, you should check the thermostat setting first. Ensure that the thermostat is set to “cool” and the temperature is set to the desired level. If the thermostat setting is correct, you should check the air filters. Dirty air filters can cause the system to blow hot air instead of cold air. If the air filters are dirty, you should clean or replace them.

Problem: The Ductless Mini Split System Is Leaking Water
If water leaks from your ductless mini-split system, the initial step is to turn off the system. After turning off the system, proceed to inspect the condensate drain line. This line is responsible for removing water generated by the system. A clogged condensate drain line may cause water to leak from the system. To resolve this issue, clear the condensate drain line to eliminate any debris causing the clog.

Problem: The Ductless Mini Split System Is Making Strange Sounds
If your ductless mini-split system is making strange sounds, you should first turn off the system. Once the system is turned off, you should check the outdoor unit. The outdoor unit contains the compressor and fan, which can be the source of the strange noises. You should check to see if the fan is damaged or if there is any debris blocking the fan. If the fan is damaged or there is debris blocking the fan, then you should contact a professional to repair the system.

Problem: The Ductless Mini Split System Is Not Cooling Or Heating Properly
When your ductless mini-split system fails to cool or heat properly, the first thing to investigate is the air filters. Clogged air filters can hinder the system’s ability to regulate the temperature correctly. If the air filters are dirty, you must clean or replace them. Additionally, check the thermostat settings to ensure the temperature is set to the desired level. If the air filters and thermostat settings are not the root cause, proceed to inspect the outdoor unit. This unit has a compressor and fan, which could be causing the issue. Check if the fan is damaged or obstructed by debris. If the fan is damaged or blocked, contacting our professional to fix the system is best.
