Baseboard heating systems limit options when it comes to installing air conditioning. A home with baseboard heat does not have the duct system that a home with a forced-air system does. Upgrading and installing ducts is costly and, in some cases, impossible. Window-based units systems is a cost-effective way a homeowner can air condition a home with baseboard heat. Window units fit most windows and can save energy costs because you only have to turn the units on in the rooms you're using at the moment.


Step 1

Choose the windows where the air-conditioning units should be placed in your home. Window units work best in double-hung windows because window that open side-to-side, for example, may not open wide enough.
