What kind of house is it heating?
Based on the old model numbers, the furnace appears to be 125k BTUs and the a/c is 3.5 tons.
If I'm correct, chances are that the furnace is grossly oversized (70k 95% eff or 80k 80% is what you would typically see in a house of your size) and the a/c is on the large side unless there's no attic insulation or a lot of window surface area.
You were quoted low end equipment.
In Canada mid efficiency furnaces aren't even available any more - they're essentially obsolete.
economic collapse is a certainty. debt based fiat currency monetary systems can never continue indefinitely because they require continuous creation of new debt to service the existing debt. in the absence of economical growth (which is always predicated on increased resource extraction rather than capital alone), this leads to massive inflation which destroys the currency.
your leaders can't fix this - they're corrupt and only exist to enrich themselves and their corporate friends.
