Yeah for new installs but service for the existing unit might be like $200 for a cleaning and it’s certainly going to be cheaper to run in the long run

Window units are built to fail, are mold prone, use an excessive amount of electricity comparatively (even the newer inverter ones) and a higher risk of injuring a person or damaging the building. Also their smart features often entice people to install apps that track you to sell to advertisers. So not only are you buying an inferior product but they’re also capitalizing of spying on you.

(tl/dr: fuck Frigidaire lol)

Call a service tech to look at your central. If it’s not keeping up then it might be cheaper to fix the issues with it over buying a window unit and paying the electricity to run it.

Central Units are typically much more powerful and therefore need to run less, and if it’s something simple like it need to have the condenser cleaned out or the refrigerant recharged the cost to just get it done is much less than the cost of window units plus electricity plus your time to install and remove them

Midea recently recalled its u-shaped unit, so be wary of used ones (I have one and now have no way to get rid of it).

There are also these GE ones that are like upside-down U’s to keep out of the way of the window; but between the unit blowing air so low as to not affect the rising hot air in the room and the fact that they have to pump the condensate up and over the window sill make me think they’re not a great investment…

This is correct, you need a “ closed” loop of outside air (by this I mean, the unit does not vent inside air through the condenser coils to the outside) and the two-pipe units are the only way to achieve this.

If you go that route, be aware that these usually collect the evaporator moisture and you either have to manually empty the bucket or pump it to a drain (you can connect it to a laundry machine drainpipe for example). If that isn’t possible and your indoors isn’t sealed well you might be emptying it a lot. Still, there are situations like smaller basement windows for which this is the only practical solution.
