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?
Not what you asked, but you might check that:
The central AC doesn’t need to be recharged. If it has leaked coolant and is low, it will drop in effectiveness.
Or, even more simply, that the air filters don’t need to be replaced.
You can’t improve insulation. Doing so is a one-off cost, as opposed to the ongoing cost of throwing more air conditioning muscle at the problem. Weatherstrip leaks, replace any single-pane windows with double-pane, etc.
Can’t improve insulation? Did you mean can? If so, yes, that’s on the to do list. We need better windows too.
Yes, those are good tips thanks.
On top of that, some rooms don’t have proper cold air return to the furnace, meaning those rooms don’t get proper air circulation and can be the reason for a room being warm. I’m experiencing this right now. One bedroom has a cold air return on the other side of the wall, but nothing in the room itself, and it’s the hottest room in the house. I gotta cut an entry to that cold air return duct.
