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?
While insulation helps, it’s fundamentally less efficient because the heat sync is inside the building and insulation isn’t foolproof. And often these units are made of plastic, so they leak more heat into the house from the chassis than you’d expect. Even the best hose is less efficient than a window unit where the entire heat sync is outside the building
So while $20 and some duct tape helps a great deal, it definitely won’t be as efficient as a window unit
