Central air problems are often a ductwork or airflow story as much as a refrigerant one, and we treat them that way.
One diagnostic visit, one flat-rate quote, no push toward an unnecessary full-system replacement.
If you're dealing with one room that never cools evenly, a system that runs constantly without ever hitting the set temperature, or a total shutdown mid-August, you already know central air complaints are frequently misdiagnosed as a simple refrigerant top-off when the real cause is airflow, ductwork, or a failing zone damper.
