Common issues that homeowners can check themselves include:

• Thermostat Settings: Ensure the thermostat is on and set to cool or heat, and check that the batteries are in good condition.
• Power Supply: Verify that the breaker is not tripped or off and that the attic light switch for the indoor unit is on.
• Air Filter: A dirty air filter can cause the system to shut down due to poor airflow.
• Water Backup: Water in the emergency drain pan can cause the unit to shut off if it's full and contains a float switch.

A 1" air filter should be changed approximately every 3 months. A 4" media air filter, typically located in the attic, should be changed every 6 to 12 months. Timeframes may vary depending on factors like the amount of foot traffic in the house (e.g., kids or pets) or how often windows are opened.

Carl's Quality provides service for Daikin, Mitsubishi, LG, and Gree minisplits. All minisplit systems contain washable filters at the indoor unit that need to be cleaned monthly. It is recommended to have your minisplit maintained twice a year and deeply cleaned once every 2 to 3 years.

In most cases, this is not normal. Typically, this pipe is your emergency drain line, which only drains if your primary drain line is clogged.

Our System Design Specialists are required to perform a Heat Load Calculation (Manual J) on your home. This confirms the capacity of the system needed for your home and takes roughly 45 to 90 minutes.
