Planning tools, not professional diagnosis.

HomeRepairMath provides general educational calculators and estimates. Results are not quotes, inspections, engineering opinions, diagnoses, or guarantees.

Actual conditions can change the answer

Equipment condition, installation quality, hidden damage, local labor costs, parts availability, warranties, permits, code requirements, climate, usage, and the exact failure mode can materially change a repair or replacement decision.

Safety comes before the score

Do not rely on a calculator result when there is an active leak, electrical damage, gas odor, combustion concern, overheating, fire risk, structural issue, refrigerant problem, suspected carbon monoxide issue, or other potential hazard. Shut down or isolate equipment when appropriate and seek qualified help.

No contractor relationship

Using this site does not create a contractor, engineer, inspector, attorney, financial adviser, or other professional-client relationship.

Verify important decisions

For expensive, safety-critical, regulated, or technically uncertain work, obtain an appropriate professional diagnosis and written quote before proceeding.
