Installs on existing ACs · No replacement needed · 30-day money-back
Your ACs are burning money every day — AC Lock stops it.
AC Lock is not an energy-saving device. It is a waste-elimination system. It stops after-hours running, locks temperature, and shows you the cost per unit — in VND.

How AC Lock eliminates waste for businesses
This is not an investment — it's fixing a leak
Imagine a water pipe in your building is leaking. Water drips 24/7, your bill keeps rising. Would you ask "how long until the repair pays for itself?" — No. You fix it because every day you don't, money flows down the drain.

No one says "my pipe repair paid for itself in 6 months." You just fix the leak.
The real question is not "when will it pay back?" — it's "how much more are you willing to lose?"
AC waste works exactly the same way. Every day your ACs run without control — forgotten overnight, set too cold, no one intervenes — money leaks out. AC Lock doesn't "generate profit." It stops the leak.
Each AC wastes millions per year through 2 basic errors repeating every day
Conservative
- ●Forgot to turn off 1x/month × 12h
- ●Temperature 1–2°C below standard, 2h/day
Install cost covered in ~3 years
Realistic
- ●Forgot to turn off 2x/month × 12h
- ●Temperature 3–5°C below standard, 4h/day
Install cost covered in ~1 year

4 operational problems AC Lock solves
Forgotten after-hours shutoff
Employees juggle priorities — AC shutdown is not top of mind when serving customers.
Automates scheduling, works offline
Temperature setpoint drift
Staff lower temps to 18–20°C unsupervised — no per-unit billing visibility.
Standardizes setpoint, prevents manual override
Data blindness
Monthly bills arrive without per-unit breakdown; you do not know where to start optimizing.
Real-time per-unit cost tracking in VND
Late failure detection
No early-warning system; small issues compound into expensive repairs.
Automatic anomaly alerts + remote intervention
Why smart home devices are not enough
Smart home products give you a remote control. AC Lock gives you a management system.
| Smart Home | AC Lock |
|---|---|
| Remote control, no audit trail | Logs all actions (who, when, how) |
| Requires smart meter installation to measure kWh | Auto-converts to VND using live EVN rates |
| No automated reports | Auto-generated monthly reports |
| Cannot verify staff compliance | Enforces management-set schedules |
| Offline = no automation | Offline automation via local logic |
