Air conditioning, laundry, and store hours

Air conditioning in the U.S.
The vast majority of buildings in the U.S. are air conditioned. This includes houses, apartments, restaurants, stores, churches, businesses, hospitals, trains, etc. The only places I can think of that aren't air conditioned are some of the dorms at my sister's university in Virginia, the camp I worked at in Maine, my friend's apartment in Boston, and all school buses. That's it. The vast majority of air conditioning is central (ducted) air conditioning. The only places you'll find wall air conditioners are in some hotel rooms. Window units can be found in some old buildings that were built before AC was invented. However, even in old buildings, many have had central AC installed.

Air conditioning in Australia
Air conditioning is standard in hospitals, trains, and grocery stores. That's about it. Some houses, apartments, stores, and restaurants have it, but definitely not all. I have only been in 1 house that had central AC. Most air conditioners in houses and apartments are wall air conditioners.

Laundry in the U.S.
Washing machines and dryers are bigger in the U.S. than in Australia. Clothes are always put in the dryer, which has a lint removing function and a wrinkle guard cycle. Clothes come out of the dryer soft and virtually lint and wrinkle free in about 45 minutes. Clotheslines are very rare and come from the first half of the 20th century. Other than my dad, I don't think I've ever met anyone living in the U.S. who hung their clothes on a clothesline to dry. Occasionally in the country, you might see a clothesline, but it's probably being used only because the owner cannot afford a dryer.

Laundry in Australia
Washing machines and dryers are smaller in Australia than in the U.S. Most Australians have dryers, but they rarely ever use them. Clothes are always hung on a clothesline and left to dry. The reason for not using the dryer is to save energy. If the weather is very sunny, clothes might be dry in several hours. If the weather is not very sunny, clothes might still not be dry more than 24 hours after being hung on the line. If the weather is rainy, clothes must be hung on a clothesline under an awning. I've also had to rush out into the sudden rain to frantically take my clothes off the outside line to keep them from getting soaked. Clothes, sheets, and towels are sort of stiff when dried on the line. They must be lint rolled and ironed, and some clothes will still be wrinkled even after they have been ironed.

Store hours in the U.S.
Most grocery stores in the U.S. open at 6 or 7 AM and close at 11PM or midnight 7 days a week. HEB is open until 1AM, and Wal-Mart is open 24 hours a day. Target is open 8AM-10PM everyday except Sunday on which it closes at 9PM. Most stores are open later on Saturdays than any other day of the week. The only days stores are closed completely are Christmas and maybe Thanksgiving, and even then, some stores will still be open.

Store hours in Australia
Woolworth's, one of the 2 major grocery store chains, is open from 8AM -9PM on weekdays, 8AM-5PM on Saturdays, and 9AM-6PM on Sundays. Target opens everday at 9AM except Sundays, on which it opens at 10AM. It closes on Sundays at 4PM, Saturdays at 5PM, Mondays, Tuesdays, Wednesdays, and Fridays at 7PM, and Thursdays at 9PM. I have seen only two 24 hour establishments since I have been in Australia, and both were convenience store type places. On some holidays, like Labor Day, stores are closed completely.
