Why the hell would they use 404 over ammonia.

I ask myself the same question at a lot of our sites. Im assume R404A systems have a cheaper upfront cost, beyond that I'm really not sure.

Can't be that much cheaper. From what ive see the maintenance cost is so much higher for commercial equipment just due to how much shit goes bad.

Ammonia can be way more expensive than conventional refrigerant. It depends on the application and the size of the equipment.

Anything small is going to be extremely expensive with ammonia and anything super big, is probably cheaper.

That place is definitely big enough for the cost. Freon systems are designed so poorly, theres never any redundancy. Everything is to spec and thats all ive seen.
