Quick answer
An AC that is not cooling can have an airflow, control, equipment or capacity problem. Before assuming the system is undersized or needs replacement, first establish whether it is operating normally.
What the symptom can point to
Cooling and heating complaints can start with airflow restrictions, controls, equipment faults, duct conditions or a real load/capacity mismatch. Treat sizing as a later question unless the system is first shown to be operating normally.
Checks that narrow the cause
Cooling and heating complaints can start with airflow restrictions, controls, equipment faults, duct conditions or a real load/capacity mismatch. Treat sizing as a later question unless the system is first shown to be operating normally.
Patterns that change the diagnosis
Pattern details are useful because they change which questions should come next. Direction, width, location, repetition and related movement or moisture signs should be considered together rather than treated as a single diagnostic label.
When to stop troubleshooting
Screen cold-air and no-heat symptoms before repair or sizing decisions. The useful interpretation comes from the combination of facts, not from repeating a generic answer. Separate operating faults from sizing and replacement decisions; do not diagnose refrigerant or electrical faults remotely.
What to tell a professional
Professional verification matters when the problem crosses the limits of an online screen. Do not instruct users to open electrical compartments or handle refrigerants. Prepare the symptom history and the facts HouseIt has collected so the first visit starts with better context.
How the HouseIt check improves this answer
The tool does not simply repeat the search query. It collects the specific facts that can change the recommendation, shows what information is missing, and connects the result to the next relevant decision. Unknown inputs reduce confidence rather than being silently guessed.
Safety and limitations
Do not instruct users to open electrical compartments or handle refrigerants.
