Is it worth the hassle to use uninstall aircon service and sell them separately before relocating?

Our family is going to move into our new home in about 2 months and are now thinking what to do with our existing big appliances. Two of them are aircon and washing machine.

We know we can just use some services in curama to uninstall the aircons (and washing machine) and just let them take it away for the least hassle. Our aircons are only around 2 years old so it will be a big profit for the curama people, and we are talking about 3 units. Washing machine is 5 years old. This would be the least hassle but worst financially.

However, if we were to just use their uninstall service and sell the aircons and washing machine ourselves, is it even worth the hassle or potential claims? Although our aircons are quite new, we could imagine the nightmare that the buyers false claiming this and that especially with that kind of big appliances which the sellers would probably have no defenses after. And we are only thinking of mercari, no experience with other methods.

Unfortunately I don't think we are considering the last option which is to move everything to the new place and reinstall again.

Appreciate your thoughts guys!
