HVAC has a
knowledge crisis

Experienced HVAC techs are retiring faster than new ones are trained. Junior techs get sent to service calls alone, spend hours on the phone with senior techs, or make costly misdiagnoses. Training takes years. The industry can't wait.

Point. Ask. Fix.

A tech points their iPhone at the AC unit, asks a question through AirPods, and Antar identifies the model, diagnoses the issue, and walks them through the fix. Or takes action for them.

1

Point

Tech points iPhone or smart glasses at the HVAC unit. Camera streams frames at ~1fps to AI.

2

Identify

AI sees the unit. Identifies the model, reads the data plate, decodes error codes, spots the issue.

3

Guide

AI walks the tech through the fix step-by-step, entirely by voice through AirPods. Hands stay free.

4

Act

Need a fan motor? Antar orders it. Log the call? Done. Text the homeowner? Handled.

A real HVAC service call, from diagnosis to action.

Hey Antar, I'm looking at this Carrier unit. The LED is blinking 3 times. What's that mean?
A
I can see the Carrier 24ACC636A003 outdoor unit. A 3-blink LED code on this model indicates a high-pressure lockout. Most common causes: dirty condenser coil, failed condenser fan motor, or refrigerant overcharge. Want me to walk you through the diagnostic?
T
Yeah, and order me a replacement fan motor just in case. Also text the homeowner that we found the issue.
A
Got it. Let's start with the condenser fan. Give me a look at the motor while I get those going.

Built for the field,
not the office

Every feature designed around one constraint: the tech's hands are on the unit.

Equipment ID

Point at any AC unit, furnace, or heat pump. Antar reads the model number, identifies the brand, and pulls up specs: Carrier, Trane, Lennox, Goodman, and more.

Error Code Decode

LED blink sequences, control board fault codes, digital display errors. Antar sees them and explains what they mean for this specific unit.

Hands-Free Voice

Entire interaction through voice via AirPods. Ask questions, get answers, trigger actions. Never put down a tool.

Agentic Actions

Order parts, log the job, text the customer, create an invoice. Antar handles it while you keep working.

Live Streaming

Share your perspective in real-time with a supervisor, senior tech, or customer. WebRTC-powered, peer-to-peer, built into the app.

Bilingual

Full English and Spanish support across UI, voice conversations, and AI responses. Your whole crew can use it, regardless of language.
