I started changing the air filters for my condos’ ACs and I would take time to scan around then and anytime a repair was needed my handyman would give me the scoop then too.

If you are paying heat/air costs, it will reduce the cost and make you happy. 

I just furnished a house to rent out and the utilities went way up due to air conditioning costs, etc. 

Stationed here because of the Air Force, but will be moving on to somewhere else in about two years. 

@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.

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..

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?
