To Add Central Air in Grand Rapids?

[David Kramer]

I am looking to purchase a home in Grand Rapids to use as a rental, but it doesn't have central air. As an out of state guy, I was wondering if any other local investors had any insight on how much of a requirement that is and what premium the market places on homes that do have central air versus those that do not. 

To clarify - the heater is a forced air furnace, so I should be able to tie into the distribution system if I were to add central A/C. I appreciate your thoughts!
