Ductless minisplit, Heat Pump Question. [View all]

We got one of these a while back. A bit beyond my comfort zone for diy, but still home improvement.

Strangely, we noticed that it seems to work drastically better when its windy outside.

Give for example a chilly day. Say, 42F outside. No wind. The thing seems to struggle to keep our room in the 50's when its set to 60. Next day, temp drops to 39, and the wind kicks up. Suddenly you can feel the heat coming off the indoor unit, and im kicking off the blankets, as it sure feels closer to 65/70 even though its still set to 60.

Can anyone explain this phenomena? Are we alone in experiencing this?
