Tenant complaining during project

[Rahel Ketema]

I am doing remodeling on my garden unit on my 3 flat. My tenant complain about every little things from noise I have given notice in advance

1, How do I approach to their complains

2, What is the appropriate time to start the builder to start working in morning

3, I put HVAC on garden unit and 1st unit so radiators were removed. 1st unit tenant wants their floor fix on radiator site ASAP. (FYI they pay their rent $500 under market value. I did not increase the rent since I purchase the property, they don't pay utilities, and also they have free one parking garage) Should i just kick them out. They have been very bothersome in so many ways. Please help.
