Hello all. Quick question that perhaps someone can help me with. Im looking to put 3 indoor units on one side of my house. 15k btu downstairs, 7k and 9k btu units in two bedrooms upstairs. I understand that mini splits modulate. The thing I dont understand is minimum output of the condenser. The condenser I was looking at is rated 24k btu. I know that if all these units are on full blast it wont be the best performance. I see a minimum btu output of the condenser is 10k as per manufacturer specs. What happens if I turn off the 15k and 9k unit? Will the 7k run by itself off that large condenser or will it cause an issue?

I have a giant tree whose root system has caused damages to a concrete driverway and the foundation. In the picture below you can kind of see what it did to the underside of the two central AC compressors. I cut down the tree last week. Now I need to lift up all these patio stones, and jack up my driveway. Then I am going to hire a landscape company to come and grind up the roots. Is there a way to set aside the two AC compressors so the stump grinder can grind the uplifting roots under the pads? Is the only option to get an AC tech to come disconnect the systems, store the coolant, move the units out of the way, then have the stump grinder come and do it's things, then have the AC tech come back to reconnect and recharge? Or is there a more creative way?
