In the house, why does heat set at 68 feel different than ac set on 68? It’s the same temperature but they feel very different!
In: Other
The temp you set is the goal temp to get the air to. You don’t get 68 degrees by generating 68 degree air. For heat, you blast 100 degree air to mix with the existing ambient air until they mix to reach 68 degrees and then the furnace shuts off. And when you want to cool a room to 68 degrees, the AC blasts 40 degree air which mixes with the air in the room until the combined temp is 68 and then the AC shuts down. But there will be hot or cold spots in the room, especially in proximity to your vents, so you may feel more of the cold AC air or hot furnace air in spots until it mixes adequately.
