# Organize equipment into systems in the ServiceTitan Field Mobile App

## Overview

Equipment Systems help you organize equipment into logical groups that work together, like a rooftop HVAC system or a kitchen refrigeration setup. By creating and viewing Equipment Systems, you can:

- Understand how equipment is connected and which units serve specific areas.
- Diagnose problems faster.
- Maintain accurate service histories.
- Ensure you're working on the right equipment for the job.

### 

#### Who uses this feature

- Technicians
- Primarily benefits Commercial Service and Replacement and Residential Service and Replacement business types
- Primarily benefits Plumbing, HVAC, and Electrical trades

#### Feature configuration

- The Field Mobile App is optimized for iOS, iPadOS, and Android phones and tablets. For more, see [System requirements and mobile app information](/v1/docs/system-requirements).
- If you're using the Field Mobile App and need support, please contact [Technical Support](http://go.servicetitan.com/ask) (through the office) or reach out directly to [support@servicetitan.com](mailto:support@servicetitan.com).
- This feature is currently in Private Preview and available for specific accounts. It is subject to change. If you want to enable this feature for your account, reach out to your CSM (through the office).
- Account configuration is required to use this feature. Please contact your office for details.
- The *Enable Editing Equipment Systems* permission is required to create or edit Equipment Systems. Please contact the account administrator on your team.

## Things to know

- Equipment Systems support the following hierarchy: System → Equipment → Sub-Equipment. You cannot create sub-systems.
- Each piece of equipment can only belong to one system at a time. If equipment is already assigned to a system, you cannot assign it to another system.
- When you assign equipment to a parent piece of equipment (making it sub-equipment), it automatically inherits the parent's system assignment.
- Deleting a piece of equipment does not delete its sub-equipment. The sub-equipment becomes orphaned and must be reassigned manually.
- Equipment does not have to belong to a system. You can leave equipment unassigned or remove it from a system at any time.
- The *Equipment Systems* view includes aggregated service history and forms for all equipment in the system, making it easy to see the complete picture.
- On Service Agreement jobs, the *Equipment Systems* view shows task progress and service status tags, helping you track which equipment needs servicing during your visit.

## Best practices

- Create Equipment Systems that reflect how equipment actually works together at the location, such as grouping all equipment that serves the same physical area.
- Use descriptive system names that include the service area or equipment type, like *Rooftop Unit A - Main Floor* or *Walk-in Freezer System*.
- Add equipment to systems as you install or service them in the field, rather than waiting to enter the information later in the office.
- Review the *Equipment Systems* view before starting a service call to understand the site layout and identify which system needs attention.
- Add tags and memos to systems to capture important details like service areas, critical equipment, or special customer requirements.
- When working on Service Agreement jobs, use the *Job-Related* filter to focus only on equipment due for service during the current visit.

## Use cases

- A commercial HVAC technician responds to a cooling problem in the produce aisle. They open the *Equipment Systems* view, find the *Produce Area Cooling System*, and quickly identify all three related units without having to search through 50+ pieces of equipment at the location.
- During a quarterly maintenance visit, a technician uses the *Equipment Systems* view to see their task progress across all units in the *Rooftop HVAC System A*, ensuring they complete servicing on every compressor and fan before leaving the site.
- A technician installs a new compressor and immediately assigns it to the existing *Kitchen Refrigeration System* so future technicians can see the equipment relationships.
- An account manager needs to prove SLA compliance to a customer. They review the Equipment Systems service history, which shows complete maintenance records for all units in the system over the past year.

## Assign equipment to a system when creating or editing equipment in the Field Mobile App

You can assign a piece of equipment to a system directly from the Equipment Record.

1. Open the Equipment Record for the equipment you want to assign to a system, or create a new piece of equipment.
2. Tap **Edit** at the top of the equipment record.
3. Locate and tap the **Parent System or Equipment** field. ![Form for adding equipment with highlighted parent system selection option.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/organize-equipment-into-systems-in-the-servicetitan-field-mobile-app-image-k8jugw2x.png?sv=2026-02-06&spr=https&st=2026-11-09T10%3A57%3A34Z&se=2026-11-09T11%3A57%3A34Z&sr=c&sp=r&sig=W2lGHtZsPIixUREvD%2Bhp5zSpwHMvrKX2GaPV0n8wp3w%3D)
4. Select either:
  - **An Equipment System:** To assign the equipment directly to a system.
  - **A Parent Equipment:** To make this equipment sub-equipment, which automatically inherits the parent's system assignment.
5. When finished, tap **Save**.

> [!NOTE]
> **Note:** You can only select one parent. If you select a parent equipment, the equipment automatically becomes part of that parent's system.

## Create sub-equipment in the Field Mobile App

Sub-equipment is equipment that belongs to a parent piece of equipment. When you assign equipment to a parent equipment, it automatically inherits the parent's system assignment.

1. Open the Equipment Record for the equipment that will serve as the parent equipment.
2. Tap **Edit** to enter edit mode.
3. Scroll to the **Sub-Equipment** section and tap **Attach Sub-Equipment**. The equipment picklist opens, showing only equipment that is not already assigned to another system. ![Form fields for asset management including warranty dates and equipment attachment options.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/organize-equipment-into-systems-in-the-servicetitan-field-mobile-app-image-4f9ihu2n.png?sv=2026-02-06&spr=https&st=2026-11-09T10%3A57%3A34Z&se=2026-11-09T11%3A57%3A34Z&sr=c&sp=r&sig=W2lGHtZsPIixUREvD%2Bhp5zSpwHMvrKX2GaPV0n8wp3w%3D)
4. Select the equipment you want to attach as sub-equipment.
5. Tap **Done** to save your changes.

> [!NOTE]
> **Note:** After equipment is assigned as sub-equipment to a parent, the Add Sub-equipment section is removed from that equipment's record. Sub-equipment cannot have its own sub-equipment.

## Search and filter equipment by system in the Field Mobile App
