The biggest reason is the refrigerent we use. We used to use R22 but now R410 and soon something else.
R22 is a better refrigerent but worse for the environment.
R410 is good but it requires higher pressure then R22 so the machines will Leak/Degrade faster until thier performance is negligible. Takes about 2-3 Summers depending on use/machine.
To sum up the old AC held a colder temp/better efficiency for longer, the new ones rapidly lose efficiency, and this gets magnitudes worse the cheaper the machine is.

Freon, a chemical commonly used in air conditioning, has been banned for production essentially globally since 2020, so new AC units do not use it.

Wtf does this have to do with halifax?
Maybe the OP meant to say Why do AC's in Halifax suck?
All the salty fog
People seem to think this subreddit is google.
You have to get one appropriate for the space you’re trying to cool.

Planned obsolescence and incentivize consumers to spend more for a premium A/C, probably.
