I am renting a house in Albuquerque New Mexico and asked the landlord a month ago to hook up the A/C. It never got hooked up and I had a party for my daughter last weekend and needed it so I did it myself. Now the landlords son is leaving rude as can be messages on my wifes phone saying we messed everything up. I checked it all when I hooked it up and everything was fine. I am also certified for working on heating and A/C and know what I am doing. The son of the landlord disconnected the A/C and continues to be rude and unproffesional about it, so I returned the attitude. I am not under contract with the landlord anymore. The 6 month lease ended 2 months ago. Do I need to give a notice on me leaving? And is there legal action I can take against them?
