SerialCheck: HVAC & Water Heater Age + Model Decoder
SerialCheck is a streamlined, offline-first tool designed for residential home inspectors, property managers, and service professionals. Quickly determine the age of furnaces, water heaters, and outdoor AC units by decoding manufacturer serial numbers, and extract useful model-number details where supported.
Built specifically to replace unreliable web-based lookup resources, SerialCheck works in basements, crawl spaces, attics, and mechanical rooms where cell signals fail. No account required, no ads, and no report-writing clutter — just fast field information you can copy into your inspection report.
KEY FEATURES:

Translate complex manufacturer serial numbers into manufacture dates.
MODEL NUMBER FIND SPECS
For supported brands, decode useful model-number details such as equipment type, nominal capacity, efficiency class, product tier, voltage, refrigerant, fuel type, water heater capacity, and tankless/tank format.
100% OFFLINE DECODING
Core decoding data is stored locally on your device. No internet connection is required for normal decoding.
GUIDED ENTRY
Select the appliance type, choose the brand, and enter the model and serial information.
