Why is my AC freezing up?
Ice on a coil or line usually points to restricted airflow or a refrigerant issue. Turn the system to fan-only to thaw it, check the filter, and have the cause diagnosed before running it again.

Understanding what your system is doing makes every service conversation shorter and clearer.
Ice on a coil or line usually points to restricted airflow or a refrigerant issue. Turn the system to fan-only to thaw it, check the filter, and have the cause diagnosed before running it again.
Most indoor leaks trace back to a blocked condensate drain, a full drain pan, or a frozen coil melting. Shut the system down to limit water damage and get the drain path inspected.
A sudden increase often reflects reduced efficiency: a dirty coil, duct leakage, a failing capacitor, or a system running longer to hit the same setpoint. Measurements identify which.
Age, repair cost relative to replacement, refrigerant type, and how the system has been performing overall all factor in. There is no single rule — the numbers should be shown to you.
It depends on filter type, occupancy, and pets. Check monthly and replace when the media is visibly loaded rather than following a fixed calendar date.
A precision tune-up is measurement work: electrical values, airflow, temperatures, drain condition, and safety checks — recorded so this season can be compared to the last one.
