凉快 (liángkuai) is an adjective meaning 'pleasantly cool, refreshingly cool' — the comfortable coolness you feel stepping into shade on a hot day or after a summer breeze.
Unlike 冷 (cold), which is often unwelcome, 凉快 is inherently positive: it names coolness that feels good. It also works verbally in the sense 'to cool off / take it easy in the cool,' as in 我们去树下凉快凉快 (let's go cool off under the tree). English 'cool' is neutral about comfort, but 凉快 built-in implies relief and pleasantness — you would not use it for a cold winter day.
It's a spoken, homey word; in weather reports or formal writing you'd more likely see 凉爽 (liángshuǎng). The reduplicated form 凉快凉快 turns it into a casual 'cool off for a bit.'
Note: Warm, everyday spoken word. The second syllable 快 is neutral tone (liángkuai). It carries a positive feeling, so it's used to welcome relief from heat, not to complain about cold.

neutral
凉爽 means the same 'pleasantly cool' but is more written and formal — you'll hear it in weather forecasts. 凉快 is the everyday spoken choice.
凉 alone just means 'cool' and can be neutral or even negative (饭凉了 — the food's gone cold). 凉快 specifically means a comfortable, welcome coolness.
