A cost estimate is not a regulatory rule
FieldPad includes a calculator historically labeled the “5,000 Rule.” Its refrigerant price-per-pound times full-charge calculation estimates the cost of a full refrigerant charge. It is not an EPA guideline, replacement requirement or compliance determination. It also differs from the age-times-repair-cost rule of thumb sometimes used in HVAC sales.
Review diagnosis, actual repair scope, labor, equipment condition, efficiency, warranty, replacement cost and the customer’s needs. Do not use an arbitrary dollar threshold as the sole reason to recommend replacement. A cost calculation does not change leak-repair obligations under 40 CFR 82.157 or 40 CFR 84.106.
