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?
No, it’s not necessarily.
From an electricity usage standpoint, it’s cheaper to inefficiently cool one room than it is to efficiently cool a whole house.
Cleaning it also may solve nothing, it’s $200 on a chance of it solving the problem. If cleanliness wasn’t the issue, then you just wasted $200. On the flip side, you can find a used window AC for $200 easily, or buy a new one for $400 and then sell it when you’re done with it and get $200 back, and it is guaranteed to solve your problem assuming you’re concerned with a specific room.
I didn’t say cleaning would solve it. I said that a service tech should look at it and it was possibly a simple fix.
Also window units will have to fight against the rest of the house being warm. Interior walls are seldom insulated, warm air drafts in around the unit and around doors. A window unit in one room could cost as much as a dedicated unit for the whole house, as it has to work harder to maintain the desired cooling.
