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 โ€” just fast field information you can copy into your inspection report. KEY FEATURES: FAST AGE DECODING 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. COPY & SHARE Copy decoded results for easy use in inspection reports, service notes, and property records. PRIVACY-MINDED No required login, no ads, and no selling user data.

SerialCheck gives you fast, field-ready appliance and HVAC decoding so you can get the information you need and move on. NOTES: SerialCheck focuses on manufacturer serial-number age decoding and selected model-number specification decoding. Supported model-number details vary by brand and appliance type. Results should be verified against the equipment rating plate when needed. Bosch and Nortek-family products are currently not supported.

About

ApplianceLog

Features
Read full description

Scan an appliance's data plate and file it as an exportable record, privately, on device, with no account. Free to start; Pro is a subscription or one-time unlock. Point your camera at the plate on a refrigerator, washer, dryer, dishwasher, HVAC unit, water heater, oven, or microwave. ApplianceLog reads the brand, model number, and serial number on device and drops them into confirmable, one-tap-correctable fields. Can't read a worn plate? Type it in by hand. Nothing is uploaded and there is no account. File every appliance under its property and unit, so a whole portfolio stays tidy, from one home to many rentals. Add purchase dates, a warranty length, condition photos, and service notes. ApplianceLog shows an at-a-glance warranty status computed from the purchase date and the warranty length you enter, so you can see what is still covered before a repair call. When you need a paper trail, export a clean per-property inventory as a PDF or CSV, on device, and share it for insurance, taxes, a move-out, or your accountant. Everything happens on this device. Your plate photos, extracted model and serial text, condition photos, and records stay on your phone. No account. No email. No upload. No data broker. With ApplianceLog you can: - Scan an appliance data plate and capture brand, model, and serial on device - Type a plate in by hand when it is too worn to read - File every appliance under its property and unit - Track warranty status, purchase dates, condition photos, and service notes - Export a per-property inventory report as PDF or CSV - Set warranty expiry reminders (Pro) For best results, photograph the data plate flat under good lighting with the model and serial lines visible. About warranty status: warranty status is computed from the purchase date and the warranty length you enter. ApplianceLog does not look up warranty coverage or product details from the serial number, and it is not a stolen-appliance lookup. Free: keep 1 property and up to 5 appliances, with full scanning and browsing. ApplianceLog Pro removes the free-tier property and appliance caps, adds PDF and CSV export, and warranty reminders. Yearly and Monthly are auto-renewing subscriptions; Lifetime is a one-time unlock. Current prices and renewal terms are displayed by the App Store purchase sheet before confirmation. A subscription automatically renews unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings > Apple ID > Subscriptions; any unused portion of the free trial is forfeited when you purchase Pro. Available in-app purchases: - ApplianceLog Pro Monthly - ApplianceLog Pro Yearly (7-day free trial for eligible accounts) - ApplianceLog Pro Lifetime (one-time unlock) Terms of Use: https://bonega.ai/appliancelog/terms Privacy Policy: https://bonega.ai/appliancelog/privacy EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
