I do have an HRV/air exchanger which is constantly pumping humid air from the outside.
This is part of the problem - turn it off in the summer and keep the basement windows closed when the dehumidifier is operating.

Your dehumidifier, if properly sized should only need to run continuously in the wettest conditions to maintain 50%. Sensors in units vary so you may have to set to 45% to have most of the basement at 50%.

The rest of the time, there should be some cycling.

Southern NB, close to Moncton. So you'd recommend Mitsubishi or Fujitsu? I've gotten quotes from lg, ge, panasonic, lennox and trane, can be confusing! Will have to sort out a decent brand and a performing output at low temperatures with a decent installer as I heard that it wouldn't matter getting a nice machine if the installer is no good



Adding all the baseboards in the 1st floor summed up to 3,250W - around 11,000 BTU
For minisplits, Mitsubishi and fujitsu are top of the market. I'd personally buy Mitsubishi for my own house. Daikin is more no bells and whistles, but still ok unit. Definitely cheaper though. We use fujitsu and daikin a lot for customers due to the price. Panasonic is decent too. Mitsubishi, Panasonic, fujitsu, Samsung all make their own compressors. Everyone else buys from them. (speaking of minisplits only hare) AFAIK trane, and Lennox only brand minisplit units. They don't actually make them. That could have changed recently, but I haven't heard anything. Chinese brands can be ok, but it's a bit hit and miss. They are definitely made a lot cheaper so your mileage will vary. (They are the cheap units you find online)

A 2ton low temp unit would likely be more then enough even in the dead of winter for you.

PS. The insulation and cover looks fine. I see no immediate problem with it. Typical installation.

Cheers!

Thanks! Will get a contractor/price for Mitsubishi and Fujitsu and post in a few days.

PS. The insulation was only because I heard that the white kind is better, I guess he was only trying to find something wrong with the previous install.
