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.
Heat Pump vs Mini Split
Compare system types using ductwork, climate, rooms and priorities. 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.

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.
