Quick answer
AC size should not be chosen from square footage alone. Climate, insulation, windows, infiltration, ceiling height and the actual cooling load can materially change the capacity a home needs.
High Humidity
Estimate a preliminary cooling-capacity range and flag when a load calculation is needed. 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 this operating pattern can indicate
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.

Inputs that actually change the size
A sizing result is only as good as the demand inputs behind it. Square footage or household count can be a useful starting point, but climate, envelope quality, simultaneous demand, equipment performance and manufacturer data can materially change the final answer.
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.
