Never lose another no-cooling call to voicemail.
Your techs are on rooftops and in crawl spaces, not glued to the phone. When a call lands and nobody can grab it, OneBy's AI picks up, gets the address and the symptom, and drops a ready-to-dispatch task in your queue. From there the same platform schedules the tech, invoices the job, and texts the arrival window, so the whole job runs in one place.

What hvac teams lose on every call.
Peak season buries the front desk
The first 90° day brings 200 calls. Every one that hits voicemail is a customer dialing your competitor before you've finished the job you're already on.
After-hours emergencies walk
No heat at 9pm is somebody's same-night job. If your line just rings and rings, that emergency premium goes to whoever picks up first.
Vague voicemails waste truck rolls
“Call me back about my AC” tells your dispatcher exactly nothing. OneBy grabs the unit, the symptom, and the access details up front.

Every call gets smarter, answered ones too.
Missed-call answering is just the start. After every hvac call, picked up at the desk, on a mobile, or by the AI, OneBy transcribes it, writes the summary, and creates and assigns the follow-up task. Nothing said on a call slips through again.
