I installed the Waykar WiFi Enabled Mini Split Air Conditioner & Heater in my 300-square-foot finished basement office earlier this week, and it has exceeded expectations in nearly every way. I’ve used several ductless systems before, but this unit stands out for its speed, efficiency, and how quietly it operates.

Cooling and Heating Performance

The performance is outstanding. Starting from 80°F, the room cooled to 72°F in less than 10 minutes. The inverter compressor adjusts power smoothly rather than cycling on and off, which keeps the temperature stable and consistent. On colder mornings, the heat mode works just as well, bringing the room up to a comfortable temperature quickly without noticeable swings.

Waykar lists this model at 20.5 SEER2, and that matches what I’ve seen in daily operation. The energy draw is impressively low, especially compared to older window or portable units I’ve owned. Because the inverter runs in a “steady state,” it avoids the power spikes typical of systems that repeatedly start and stop.

Noise Level

One of my favorite parts of this unit is how quiet it runs. The indoor head is nearly silent on low and medium settings. Even on high, the sound is just smooth airflow rather than the harsh mechanical noise that older units make. During work hours, it’s barely noticeable on Zoom calls. At night, it fades into the background entirely.

The outdoor compressor produces a low hum that blends into ambient noise. Standing just a few feet away, it’s audible but never intrusive. For a system this powerful, the overall noise control is impressive.

Smart Control and App Features

The smart control options are another highlight. Using the Waykar app or Alexa makes it simple to manage temperature and schedules. I created a routine where the office cools automatically before I start work and warms up again in the evening. The app also allows quick manual adjustments, so I rarely touch the remote anymore. Voice control through Alexa is surprisingly responsive and convenient for small thermostat changes.

Design and Build Quality

The build quality feels sturdy and reliable. The indoor unit looks clean and modern, and the materials feel substantial. The system includes a self-cleaning function and washable air filters. I recommend rinsing the filters every few weeks and running the self-clean cycle periodically to keep the coils dry and prevent musty smells.

This version uses a 115V connection, so I didn’t need to run new wiring, which saved time and cost. A professional installer handled the refrigerant lines, vacuuming, and mounting. Once powered, setup was simple — connecting to WiFi and linking to Alexa took just a few minutes.

Energy Efficiency and Maintenance

This unit runs efficiently without wasting energy. Because it continuously adjusts rather than turning on and off, it maintains comfort while using less power. I’ve seen noticeably lower energy usage compared to older systems. Routine maintenance is straightforward. Cleaning the filters and occasionally running the self-clean feature is all it needs to stay in top shape.

Verdict

The Waykar Mini Split Air Conditioner & Heater combines excellent performance, energy efficiency, quiet operation, and smart control in one well-designed package. It cools and heats quickly, stays nearly silent, and holds your set temperature without fluctuation. The build feels solid, and installation was straightforward thanks to the 115V model option. For a medium-sized room or office, this system provides year-round comfort with minimal energy use.

If you want a dependable, quiet, and efficient mini split that’s easy to control and maintain, this model is a top choice. It’s one of the best all-around units I’ve owned and well worth recommending.
