Reply to comment by FiftyTigers in TIL Snow is an excellent insulator because it consists of about 90–95 percent trapped air (fresh). This is the reason why igloos are warmer inside than outside, and why some animals in colder regions build snow caves to spend the winter while hibernating. by SunCloud-777

Where I live, we have winter snow for at least five months. I cannot say that I have noticed that issue where I live. houses here feel colder in the winter because it is colder outside. People tend to not pile snow up against their homes because they don’t want extra water in the spring to intrude into the basement. The homes where I live are typically insulated well enough that snow piled up would not really affect the temperatures of a home. I suppose that snow piled up against the house would block solar heat gain during the daytime.
