Should We Install Central Heat & Air?

[Brandon G.]

We are buying a property in a C neighborhood in Garland, TX where most of the houses do not have central heating and air. However, of the 3 houses for rent in the area, 2 of them had central ac. Our property has only window units and gas heater with floor vents. 

So I am wondering if we should consider installing central ac in our rent property. How much more rent income should we expect to get if we did install one? 

One thing to note is we are considering section 8 as an option. I was told that window units may not qualify for their standards. Is this true?
