@Jessica Jay-Maleski, since I'm sure air conditioning is a must in your area, I might consider upgrading the units to have ductless mini-split air conditioning systems.

I got him to a chair, called 9-1-1, and put heavy pressure on his arm with a wrapped towel until the EMTs showed up.

Tenant erected a 12 x 12 outdoor extendable living accommodation shed in the backyard without any permission installed permanent tiles, ran wiring in the shed for lighting, fans, for electrical devices and also for air conditioning.

My property was on the market two weeks and was able to get it rented by an Air force couple..

@Jeremy VanDelinder , FYI, we moved the meeting to a new location where we don't have the pressure of time like at RR library and the setup is much better (and the cost is much better than at the library), so networking should be "smoother" - sorry if we failed you in this. 

Baltimore Air BnB is under attack....the new bill that goes into law shortly, essentially bans short term rentals in homes that you don't currently live in.

I would have central air/heating repaired.

Is it a window AC unit or is it a Central air unit?

At this time I would pressure them to replace the unit (warranty should be transferable) and they will fix the noise prroblem.

A high tech air filtration unit, a newer heat/ air unit?
