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

I typically use a ceiling fan for the summer and a space 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 HF1’s smart features that made this appliance particularly handy. Dyson provided the HF1 unit, which will be returned to the manufacturer.

Although you can control the HF1 using the onboard 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 the 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 its display. I’m a light sleeper who prefers complete silence at night, and I was able to adjust the fan noise quickly.

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

The HF1’s intelligent thermostat continuously monitors the room and automatically adjusts its heating output to reach and maintain your 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’s temperature.

One of my favorite features about the HF1 is its bladeless design, which makes it incredibly easy to clean. A quick wipe with a cloth is all it takes to remove dust, and unlike traditional fans and heaters, you don’t have to clean any grilles or blades. 

The bladeless design also makes it a safer choice for homes with pets and children, as there are no exposed blades for curious hands or paws to get caught in. However, the metal casing around the front of the HF1 can get slightly hot to the touch while it’s in the heating mode.

Another nice safety feature is that the fan automatically shuts off if it’s tipped over. 

In terms of size, the HF1 is compact and light, weighing just under six pounds and standing 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 comes with a premium price tag, it’s 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 space heater or fan.
