I live in Ohio and it was getting pretty hot outside.  I put an apartment addition on to my home.  It was built over top of one of garages.  I have a 2 car garage home w the main house being over the other garage.  I purchased the 6,100 BTU conditioner.  It cools that area perfectly.  Ive had no problems with the unit.  Runs  quietly.  I am really glad that your company sent messages to tell me to not run the air conditioner for 24hrs. This lets the unit settle because of the coolant.  Ive never had a window unit. This was important info for me.  I wouldve set up the unit and plugged it in and started it right up.  Thank you so much.. If down the road I have any updates on this unit, I will share.
