Tag the equipment
Place a Tech Was Here QR service tag on the unit, scan it with the phone camera, and link it to the customer, site, and equipment record.
Give every HVAC unit a simple path back to your team.
A technician places a QR service tag on the condenser, furnace, air handler, or ductless unit. When comfort changes later, one scan opens the exact unit and sends the request to the HVAC company that already knows it — no app, login, or search required.
Keep the service relationship attached to the equipment.
Tech Was Here supplies the durable tag. Your technician creates the connection in the field. The homeowner uses it later when service is needed.
02 · Homeowner or site contact
Scan when help is needed
The camera opens a simple page for that exact unit and names the current service company. No app, account, or login is required.

Receive the request
The issue reaches the team with the claimed customer, site, and equipment context already attached, ready for follow-up in the existing service workflow.
The physical QR service tag measures 3 × 1 inches and is enlarged in these illustrations for visibility.
Made to stay visible on the equipment your team services.
This is the actual 3 × 1-inch QR service tag on an outdoor condenser. The fixed panel keeps it easy to find without covering the manufacturer badge, coil openings, or routine service access.
Make the next HVAC call easier to recognize and return.
HVAC equipment can stay in a home or commercial site for years, while paperwork and contact cards disappear. The QR service tag keeps a service entry point on the unit itself. The homeowner does not need to search old email or begin with a generic web form.
In the intended workflow, the request reaches your team with the tagged equipment and site context already connected. That creates a clearer path to the next service conversation without claiming that every scan becomes a booked call.
Start with identifiable, long-lived HVAC equipment.
Choose placement carefully so the tag is visible, scannable, and appropriate for the equipment environment. The tag should never cover safety information, manufacturer labels, controls, vents, or routine service access.
Outdoor HVAC units
Tag condensers and heat pumps with a durable scan point that stays with the exact unit your company installed or serviced.
Furnaces and air handlers
Keep the unit and service-company context available for the next maintenance or repair request without putting private customer details on the public page.
Ductless systems
Connect an identifiable indoor or outdoor component to the service-company and request path that should handle the next service conversation.
Commercial mechanical equipment
Give rooftop units, boilers, and other long-lived mechanical equipment a stable path back to the team that services the site.
Make similar systems easier to tell apart.
The scan should answer three questions immediately: which unit is this, where is it, and which company services it? That context is especially useful in multi-system homes and commercial sites where a generic HVAC request can be ambiguous.
Put the tag where it can be found and scanned safely.
- Keep the tag clear of manufacturer plates, warnings, controls, vents, and service access.
- Choose a fixed, stable surface that stays with the equipment and is appropriate for the environment.
- Make the tag visible without asking the customer to open a panel, climb, or enter a hazardous area.
- Use a clear equipment name and location when a site has more than one HVAC system.
- Scan the placed tag before leaving and confirm the public page shows the correct unit.
Use the full QR service tag placement guide for outdoor units, air handlers, rooftop equipment, and other service categories.
Start with the equipment-level path back to your service team.
Put the tag, homeowner request, private workspace, and maintenance reminders to work first. As your team uses the platform, the workflow can grow around the needs technicians and office staff surface. See the service company workflow or review pricing for your team.
What is an HVAC QR service tag?
It is a durable QR tag supplied by Tech Was Here and placed on an HVAC unit by your technician. After the tag is linked to the equipment, a later scan identifies the unit and current service company and opens a service-request path.
Does the homeowner need an app or account?
No. The phone camera opens the equipment page. The homeowner can recognize the unit, see the current service company, call, or submit a short request without installing an app or signing in.
Can a technician tag equipment another company installed?
Yes. The workflow is designed for equipment your company installs or services. Your technician claims the tag during an authorized visit and manages that service relationship in the private workspace.
Who supplies the physical tags?
Tech Was Here supplies serialized QR service tags that associate with the company when an authorized technician claims them. Service-company users do not create their own public scan links. Tag quantities, fulfillment, and setup are coordinated during onboarding.
Where does Tech Was Here fit in an HVAC workflow?
Tech Was Here starts at the equipment. It turns a completed visit into a direct path for the homeowner to identify the unit and send the next service request back to the company that knows it.
How does a tag support repeat service?
The tag keeps your company connected to the equipment and gives the homeowner a low-friction way to reach your team when the unit needs attention again.
Give the next serviced unit a path back to your team.
