Hot Mobile Homes

Mario Gonzalez is suffering from a hot mobile home in San Diego, CA.

He's probably so hot he can't make the connection between his hot home and his car.

Here's what he sent:

"I've noticed that my mobile home gets hotter during summer than the outside temperature.

I feel the hot air that builds up during the day and is not exhausted.
I want to either install a whole house exhaust fan, or one small bathroom exhaust fan per room.

I'm worried that during winter, the cold air will come in the house and that I'll make things worse. Any suggestions?"

Here's my answer.

Mario, have you ever thought about why a car that sits in the sun is so hot when you get inside it?

Have you ever touched the metal roof of a car that's been in the sun and burned your finger?

The sun's infrared rays heat up the metal and the temperature of the metal can get well above 120 F or more.

The same thing happens to your mobile home or anything left in the sun.

The hot object radiates the heat much like a glowing piece of steel or a campfire.

Your body feels that radiated heat.

A whole house fan is your best bet.

I can't believe you're complaining about winter in San Diego! You want cold, come visit me here in New Hampshire the third week of February!
