Why Rooms Over Garages Stay Hot in Stafford Summers
Rooms built over an unconditioned garage are notorious for being the hottest room in summer and the coldest in winter. They are exposed to outdoor temperatures on five sides: the roof above, exterior walls, and the unconditioned garage ceiling below. Long central duct runs frequently fail to deliver sufficient static pressure to overcome this intense thermal load.
Installing a dedicated mini split directly inside the bonus room provides dedicated cooling and heating. You can set the room to your exact desired temperature without altering the thermostat for the rest of your Stafford home.
