⚙️ Your Spare Parts Should Know Which Unit They Go To

Walk into almost any commercial mechanical room and you'll find the same shelf: loose filters in a few different sizes, a bin with a couple dusty belts, and a capacitor leftover from a job five years ago. No labels. No paperwork. To know whether you're covered for a specific unit in an emergency, you either rely on memory or call the last tech who worked on it.

An inventory list helps with counting, but it doesn't solve the more fundamental problem — the connection between what's physically on the shelf and which specific piece of equipment it actually goes to. That connection is what the spare parts system in Equipment Tracker Pro is built around.

Know What You Have Before You Step Foot on the Roof

When you add a spare part in the app, you link it to the equipment it belongs to. That connection runs in both directions. Open any piece of equipment — a rooftop unit, an air handler, a boiler — and the parts tab shows every spare tied to that unit with a live on-hand count. Open any part from the inventory screen and it shows you exactly which unit it services.

That **bidirectional link** solves two problems that come up constantly in the field:

The **public QR scan page** for each piece of equipment also displays the parts list and current on-hand counts. A contractor who scans the equipment tag before heading to a job site can see what's already stocked there — that alone cuts down on a significant number of wasted supply house trips.

Read Belt and Filter Stock at a Glance

Belts and filters each require two critical data points: the **application name** (what it services) and the **exact size** (what to order). Inventory cards now display both on separate lines — no tapping or digging required to verify what you're looking at.

Tapping a card opens the full part profile: size, name, which unit it goes to, current on-hand count, and storage location. In a building with several air handlers running different belt sizes, you can tell every unit and its stock status apart without opening anything else.

Storage Locations: Where Is It Actually Sitting?

Knowing you have two spare belts in stock is useful. Knowing they're in the parts cabinet in the basement mechanical room is what actually saves you time when you need them.

Every spare part has an optional Storage Location field. You can enter anything that describes where the part physically lives — "Shelf C", "Truck 4", "Parts Cabinet - Boiler Room", "Building A, Storage Closet". That location shows up with a pin icon on the part profile and in the inventory list.

For teams that keep parts spread across a shop, multiple trucks, and on-site storage at different buildings, this closes the gap between knowing something is in stock and actually being able to put your hand on it without making phone calls.

Replicate Parts Across a Fleet Without Re-Entering Everything

Large portfolios often have the same equipment model installed across multiple buildings or floors — identical rooftop units, a row of fan coil units on every level of an office complex. Once the parts profile is set up on one unit, the app lets you push that setup to other units of the same type. Select the parts you want to copy and they transfer to the target unit with all counts and details intact.

This is most useful when you're building out inventory records for the first time and want consistent coverage across a fleet without entering the same part information fifteen times over.

The AI Nameplate Scanner Prevents Duplicate Records Over Time

When you capture a spare part using the **AI Nameplate Scanner**, the system automatically cross-references the equipment's existing parts list before creating anything new. If it detects a match by manufacturer, model number, or specifications, it prompts you to merge the scan into the existing record instead of creating a duplicate.

Merging appends the new photos directly into the existing part's gallery, increments the stock count, and folds in any additional spec data — all without touching the original record. On equipment that sees multiple technicians over the years, this keeps your parts list accurate without anyone having to manually audit for duplicates.

Distinguish Full Backup Units from Consumable Parts

A spare condenser sitting in a warehouse is not the same thing as a bag of belts on a shelf, and the app now treats them differently. When you add a spare part, you can designate it as either a sub-component (a motor, a capacitor, a filter) or a complete replacement unit for the entire piece of equipment.

Parts designated as full replacement units display a **Spare Unit** badge in equipment and inventory lists. During a critical systems audit — checking whether backup equipment exists for anything that would take a building offline — the badge is immediately readable without opening individual records.

Spare parts tracking in the app is available now. You can add parts from the equipment detail page or from the inventory screen, link them to any unit in your buildings, set storage locations, and adjust counts with the plus and minus controls. Stock levels stay in sync across the app, the web dashboard, and the public QR scan pages for each unit.
