House is always cooler than outside?

[MrJMan]

Hello, I have a house built in 2007 and it is well insulated. The small gaps I seen I used Great Stuff foam insulation to cover them up myself. In the summer it was great that it was always nice and cool on hot days without the AC. OH I forgot to mention that I have only lived here for a month, so I haven't experienced the cold weather yet.



It is currently 71F outside, but I am actually cold. So I wonder if in the winter when it is really cold, would I be freakin freezing? Or will my house be able to trap the heat from my heater?

your house will retain the heat from your furnace just as it held the cool air in the summer...
