My friend was running 2 dehumidifiers in his basement.
He complained that the dehumidifiers were heating the house up during the day causing the slightly under sized central A/C to run well into the night when he turned it on in the evening.

I recommend that he toss the stupid dehumidifiers and add an A/C discharge in the basement and cut a hole in the intake duct. And leave the air conditioner on, but turned up to 80 to 85 during summer days.
That kind of worked.

So next he pulled a section of intake duct out.
Now he says it works great. He says including the basement in the hvac circuit cools the house down with in a few minutes because the air mass in the basement is like a cold thermal storage and circulating the air is enough to keep the basement nice and dry. Much dryer than the dehumidifiers were ever able to keep it. He also keeps the A/C off during the day.
He also says doing this has reduced the power bill by 1/3.
