How HouseIt reaches this result
HouseIt combines the answers you enter with the decision mode for this tool—diagnose. It uses the combination of facts rather than treating one symptom, age threshold or rule of thumb as definitive.
What this tool cannot verify remotely
HouseIt cannot inspect concealed conditions, confirm code compliance, perform licensed calculations, measure electrical or combustion conditions, or replace an on-site professional diagnosis where one is required.
What this HouseIt tool considers
Separate operating faults from sizing and replacement decisions; do not diagnose refrigerant or electrical faults remotely. The decision flow uses inputs such as airflow, thermostat, filter, outdoor unit, system age, capacity, heat pump, but only where they can change the result.
