Yesterday, for the first time in our married lives, we got air conditioners for our home. Growing up, we actually never had air conditioners, but just used fans, and were totally fine. A year or two before we moved away from Northeast Ohio, my parents installed central air conditioning in our house to increase its market value.
Then we moved abroad, and again, no air conditioning.
This September, we'll have been married 11 years, and we've never had "real" air conditioning in our house. We started off using fans when necessary, and trying to avoid using fans when those weren't necessary, to keep down our electric bills. One summer we were just so miserably hot that we bought a portable second hand air conditioner for our bedroom (we were co-sleeping at the time, so it was for the entire family). It stood up on the floor, connected to one of the windows with a pipe, and worked... sort of. During times when the fan blowing on you simply felt like a car exhaust blowing on you, this portable air conditioning unit was a welcome relief even if it didn't actually make you comfortable, but it did a terrible job of actually cooling down the room. It just made it marginally better. And we didn't have any air conditioning in the living room/dining room/kitchen. The portable unit we had was barely strong enough for our small bedroom, let alone the bigger living room/dining room/kitchen. And the children's room was built in such a way that we couldn't put any air conditioning there.
So essentially, no AC in our place.
In the winter, we used blow heaters and radiators and halogen heaters...
Yesterday we finally bought real air conditioning units that double as heaters (I think they are called split system heat pumps). The same unit warms the place in the winter as cools it in the summer. It is supposed to be the most cost efficient way to heat your home here. When we designed the layout of our new home, we had them build it with preparations already there for the air conditioning units, so we wouldn't have a large expense to install them (places for pipes and electricity).
But we spent most of the winter here without those units, since I didn't get around to ordering and installing them.
Finally on a price comparison website I found some decent pricing for these AC units. One large one for the living room/dining room/kitchen, and one small one for my bedroom. The kids' room is right near the living room/dining room and should be able to be cooled or heated from the adjacent room, but if not, we may also put the portable AC unit in there. We also put an air conditioning unit in our rental unit's living room. (They brought and installed AC units from their old home into two of the bedrooms.)
