* Geographic location: Colleges in warmer climates are far more likely to have air-conditioned dorms than those in cooler climates.
* Age of the building: Older dorms are less likely to have air conditioning than newer ones.
* College resources: Wealthier colleges can more easily afford to install and maintain air conditioning.
* Individual dorm policies: Even within a single college, some dorms might have air conditioning while others don't.
To find out if a specific college has air-conditioned dorms, you'd need to check their website (often in the housing section), contact their housing office directly, or look at student reviews online.
