We have to buy a window unit for our house. We have Central AC but it’s not keeping up and we can’t afford to upsize it right now. So until then I’m researching which window units to buy. Any advice or anything to cut through all the marketing spam and AI copy that I have to wade thru?
Look for a high SEER, https://en.wikipedia.org/wiki/Seasonal_energy_efficiency_ratio
Window AC can be much cheaper to operate than central even if the window unit is less efficient, since it’s cooling just one room instead of the whole house.
Where I am, we’ve had some quite hot days (100 degrees but not much above that so far) and I haven’t had to use the AC yet, because it’s still pretty cool out at night and the house stays cool enough during the day. That might change if it starts getting hot at night.
