 What's the average of a unit, would you say, Eddie? It depends on the size unit. But right now, a friend of mine just bought basically a five-and-a-half-ton unit. It was right at $10,000, about $11,000 to install. Yeah, but how many years do you think they usually last? Maybe 20-plus years out of that unit because he bought the right one this time. Okay. So maybe this is something if you're buying a house or you're renting, you want to talk to your landlord, be like, okay, it's time for a new unit to be put into this thing.
