The Dyson Hot+Cool HF1 is a stylish 2-in-1 smart appliance that provides heating in winter and cooling in summer. Designed for year-round convenience, the $499 unit combines quiet operation and smart controls with Dyson’s signature bladeless design.

I usually use a ceiling fan for the summer and a heater for the winter. After three months of testing, the HF1 was a game-changer for me, and not just because it replaced two appliances. It was the HF1’s smart features that made this device particularly useful. Dyson provided the HF1 unit, which will be returned to the manufacturer.

While you can control the HF1 using the built-in controls or the included remote, you can also operate it from your smartphone with the MyDyson app. I found it especially convenient to turn the HF1 on or off from my phone, even when I wasn’t in the room, as well as set timers, adjust oscillation, and create schedules so it would automatically turn on whenever I wanted.

The HF1 is quiet enough for bedrooms and home offices. In sleep mode, it operates at just 26 decibels and automatically dims your screen. I am a light sleeper and prefer complete silence at night and I was able to adjust the fan noise quickly.

The HF1 features an adjustable tilt that allows you to direct airflow where you need it. For wider coverage, it can be adjusted to oscillate at 15, 40 or 70 degrees.

The HF1’s smart thermostat continuously monitors the room and automatically adjusts its heating power to reach and maintain the chosen temperature. One important caveat: The HF1’s cooling mode is essentially a high-powered fan, not an air conditioner, so it circulates air rather than lowering the room temperature.

One of my favorite features of the HF1 is its bladeless design, which makes it incredibly easy to clean. A quick wipe with a cloth is enough to remove dust, and unlike traditional fans and heaters, there is no need to clean grilles or blades.

The bladeless design also makes it a safer option for homes with pets and children, as there are no exposed blades to trap curious hands or paws. However, the metal casing around the front of the HF1 may become slightly warm to the touch while in heating mode.

Another nice safety feature is that the fan automatically turns off if it tips over.

In terms of size, the HF1 is compact and lightweight, weighing just under six pounds and measuring 23 inches tall. Its slim design made it easy to move from room to room without taking up too much space or looking out of place.

While the HF1 is priced higher, it is a worthwhile investment if you want a single appliance for year-round use. Its combination of heating, cooling, smart features, quiet operation and easy maintenance makes it a compelling upgrade over a standard heater or fan.
