AC Savr automatically pauses your mini-split when doors or windows open. Works with hardware you already own. No electrician. No rewiring.
Free during beta · No credit card required
Mini-splits are incredibly efficient — until someone leaves a door or window open. When that happens, your unit fights a losing battle against outdoor air, burning energy and shortening compressor life.
The U.S. Department of Energy estimates that 15–30% of heating and cooling energy is wasted from air leaking through open doors and windows. Most people don't notice until the electricity bill arrives.
Your AC has no idea what's happening on the other side of the room. It just keeps blowing.
Kids, pets, guests. AC keeps running.
Ventilation vs. AC battle.
No alarm until the bill arrives.
AC Savr connects sensors you already own to your mini-split controller. No new hardware required if you have YoLink sensors and a Cielo Breez.
Place a small wireless sensor on every door or window near an AC unit. YoLink sensors cost $10–$15 each, last years on a single battery, and work through walls with a 1,000ft range.
Wireless, long-range, 2+ year battery
One per home, connects all sensors
A Cielo Breez controller sits near your mini-split and communicates via IR — the same way your remote does. It gives your "dumb" mini-split an API. Takes 5 minutes to install, no electrician needed.
IR blaster for mini-split control via API
Already have a Cielo? Great — AC Savr works with your existing controller.
In the AC Savr dashboard, map each sensor to the HVAC units it should control. When a sensor trips, AC Savr automatically pauses only the affected units. When the door closes, your AC resumes — with configurable delays to avoid rapid cycling.
Track every open/close event and HVAC action. See exactly when your system pauses, resumes, and how much runtime it prevents.
Based on DOE estimates of 15–30% energy waste from air infiltration. Your actual savings depend on usage patterns and climate.
Less wasted runtime means less compressor wear, lower electricity consumption, and a longer lifespan for your mini-split.
