Common Mini-Split Drain Issues in Humid Houston

Because mini-split wall units pull heavy amounts of moisture from humid Houston air, their internal condensate drain troughs require regular cleaning. Microbial slime can plug the 5/8-inch drain tubing, causing water to drip down interior drywall. Clearing the drain line and treating the pan with biocidal strips prevents water damage.

Frequently Asked Questions

Blinking LED lights or error numbers indicate a fault such as an open thermistor sensor, communication failure between indoor and outdoor units, or high compressor discharge temperature. A technician can read the code and test individual circuits.

Yes, but mini-splits use critical refrigerant charges measured in ounces. If a flare fitting leaks, the leak must be repaired, the system evacuated, and the exact factory charge weighed in with a digital scale.
