Nothing like planning everything out or thinking your set to have it turned upside down

Even in NH it doesn’t work that well.

Most of May and early June we thought summer heat would never come, super dry and cool at night.

Ever since mid June we’ve had humidity levels 60-99% with temps never dropping lower than mid 60s. AC isn’t all about cooling it’s also about sucking moisture out of the air. I run our mini splits on dry and low fan way more that on cool. I’ll let the temps claim in the house to mid 70s but with dry air it’s very very comfy.

Doesn't work that well here either. We have about 45 minutes in the spring when we can open the windows and maybe 15 minutes in the fall. Even those are iffy.

Another issue is second floor bedrooms. I live in a generally mild climate but need to run the A/C at night just to bring the bedroom temperature down to 2-3 degrees above outdoor ambient. Opening all the windows (4 sides!) takes until 2AM to cool down enough.

What @740GLE said. It's not the heat, it's the humidity, for us here in Maine.
