Once we got new water heater, new furnace, new air conditioner, and were ready to rent, we (the property manager and I) realized that the copper wire had been vandalized as well.  

Turns out- the cat used the air vents as it's relieving stations, (the air conditioner was now part of the problem) as well as at the base of the staircase, and the wood trim was saturated as well.

Who's cleaning the toilets and where do people store their hair products and why is my conditioner empty after just one week?

We are renovating a 6-unit in which we removed the window and under a wonder (think motel style) air conditioner and replacing with mini-splits.

I know of one of my investors friends that had an air conditioner 2" over the property line and the people who bought the vacant lot next to him caused him so much trouble over the 2" easement he ended up selling the property. 

The particular situation I’m am in need of guidance on is a new tenant we have recently put in one of our homes and this person feels the need to text myself and my partner every time the house makes a noise or the air conditioner makes a sound they think is a problem or when the weather is bad and the lights blink......the list goes on and on.

She has claimed an air conditioner bill that she can't produce that she said got trashed.

Roof, Air Conditioner, etc?

We have experienced this over and over where the owners are spending money on deductibles and then we have to send out our maintenance people to fix the problem.Our next problem came in the form of a malfunctioning air conditioner.
