Keep Your Space Comfortable Year-Round with the DEMULLER 12000BTU WiFi-Enabled Mini Split AC & Heater

Why We’re Impressed by DEMULLER’s 12000BTU Mini Split

We recently installed and tested the DEMULLER 12000BTU WiFi-enabled mini split in a 700 sq ft living area—and it blew us away. From rapid cooling on sweltering afternoons to gentle heating during chilly mornings, this unit offers exceptional climate control with whisper-quiet operation. Its sleek white design blends seamlessly into any décor, while the included installation kit made setup surprisingly straightforward for DIYers and professionals alike.

Energy Savings You’ll Notice: 22 SEER2 Efficiency

With a 22 SEER2 rating, the DEMULLER mini split delivers top-tier energy efficiency—cutting power consumption by up to 30% compared to many traditional HVAC options. During our three-week trial, we monitored electric usage daily and saw our cooling costs drop by nearly 20%.

Smart Home Ready: WiFi Connectivity & Voice Control

Pair the AC unit with DEMULLER’s mobile app to adjust temperature, fan speed, and modes from anywhere. We seamlessly integrated it with Alexa and Google Assistant; a quick voice command was all it took to turn on heat before we got out of bed or ramp up the fan on a hot afternoon.

Whisper-Quiet Operation for Maximum Comfort

Thanks to its advanced compressor and precision-balanced fan blades, noise levels stayed below 45 dB even on high-speed settings—about the sound level of a quiet library. We could watch movies, take Zoom calls, and sleep peacefully without intrusive hum or vibration.

Installation Kit Included: Simplified DIY or Pro Setup

The package comes complete with a 16 ft refrigerant line, mounting bracket, vacuum pump adapter, and all necessary hardware. Our installer had the indoor and outdoor units mounted, sealed, and running in under three hours—saving time and additional parts costs.

Clean, Modern White Finish

The minimalist white indoor unit fits flush against drywall, while the outdoor compressor unit sports a rugged, weather-resistant casing. We appreciated how unobtrusive it looked on our exterior wall and how easy it was to wipe down for maintenance.

How It Performed in Real-Life Conditions

During peak summer days, the DEMULLER cooled our test room from 85 °F to 72 °F in just 12 minutes. In heating mode, it raised the temperature from 60 °F to 70 °F within 15 minutes, providing steady warmth with no cold spots. The dedicated dehumidification mode also kept humidity levels at a comfortable 45–50%, perfect for areas prone to muggy air.
