Central A/C or not??

[Alex Smith]

Good Morning BP! 

Just thought I'd stop in here to see what others would do or have done....

We recently purchased a 6 unit distressed property. The property is comprised of a triplex, duplex and single family home. 

We are currently working in the triplex and when we purchased the property, everything was a little odd. I believe at one point this triplex was a single family home, so it had 1 oil tank servicing the heater for all 3 units- yikes. We got rid of that and had 3 gas meters installed. We are getting new ductwork/heaters for all 3 units so now I'm wondering...should we take that one step further and do central a/c too?? 

We just installed all new windows in the building and it would be really nice not to have a bunch of a/c units hanging out of them in the warmer months. Yes, it's more costly up front, but I'm assuming in time it would pay off and obviously add value to the property. Thoughts? What would you do or what have you done?
