I imagine there will be a lot of AC retrofitting across Europe in the coming years. Investment opportunity?

Ventless temperature control units are extremely popular there so it's probably not an unwise investment but you're not really ahead of the curve. The construction of most European buildings[1] lends itself poorly to anything that requires knocking a hole in a wall but the systems that can exhaust heat through water lines are usually quite reasonable to set up.

1. Though this is significantly less prevalent in Spain due to a lot of reconstruction happening after the civil war - that isn't to say buildings there are perfect, they just have different problems than the classic German 30cm thick stone wall.

The price of AC gases had skyrocketed by EU laws, and more than half of the bill are just taxes.

Some gases, like ammonia are easy to manufacture, other are being banned by environmental concerns, and other depend on international trade nets that can be shocked at any time if somebody trumped that morning. Investing in AC should depend heavily on the kind of refrigerant used in your product.
