An air conditioner or mini-split that runs all day without cooling, freezes up, or drips indoors usually starts with airflow or drainage, not with refrigerant. A dirty filter, blocked return, closed registers, or a clogged condensate drain produce most of these symptoms. Low refrigerant means a leak in a sealed system — topping it off without finding the leak is a repeat bill, not a repair. Thaw a frozen coil once, with cooling off and the fan on, and call if it freezes again.
Cooling problems arrive in summer, when a system is asked to run for hours and every airflow restriction shows up at once. Homeowners often ask first whether the system is out of refrigerant, but in the material homeowners share, airflow and drainage come first: the same clogged filter that freezes an air conditioning coil in July short-cycles a furnace in November. The checks below separate an airflow or drain problem from a refrigerant or electrical fault.
What you notice
- Weak or lukewarm airflow, endless runtimes, and a house that never reaches setpoint.
- Ice on the indoor coil or on refrigerant lines outside.
- Water appearing after ice melts, or a steady drip from the indoor unit.
- An outdoor unit that will not run while the indoor fan runs, hissing or bubbling sounds, or a musty smell. For mini-splits: one head weak while others work, water dripping down a wall, or a flashing error code.
