Mobile Home Cooling

Awnings, sunscreens, trellises, and shade trees are some of the ways homeowners block solar heat in summer.

The keys to reducing air conditioning costs in mobile homes are to shade the windows and either shade the roof or coat it with a reflective coating. Solar screens and window films are good immediate solutions to window shading. However, it’s ideal to stop the sun before it even gets near the home.

If you live in a humid climate, moisture can increase your cooling costs because your air conditioner must take moisture out of the air to produce acceptable comfort. In mobile homes, the moisture comes from two main sources. The first source is moisture migration from the ground. Every mobile home should have a plastic ground-moisture barrier. The second source of moisture is air leakage, so sealing air leaks will also reduce air-conditioning costs. Check the following links for more information on moisture control.

  1. will aluminum foil over glass in windows reflect the sun rays and make th3e mobile cooler inside?

    1. Maybe somewhat cooler, but not just because of the reflectivity. It’s more about blocking the solar gain through the glass. A piece of cardboard, blinds, or curtains would do the same thing. But then you can’t look out the window and no daylight gets in.

      A better option might be external shading. Like an awning. You keep visibility but block the solar gain through the window. It’s difficult to say how much cooling you’d get just from shading the windows. You still have solar gain through the roof and walls. But shading the windows will help. Especially for windows that face South and West.
