Its really expensive, its true. Prices spiked like mad after the coronavirus shortages, AC parts were back up forever. It sucked and the costs rose tremendously and seemingly never fell. Then we tarrif the imports and change the rate constantly. Nobody can sort out their supply chains(But it is not just the tariffs).

The refrigerant is often expensive, poisonous and flamable. We don't replace the refrigerant, we reclaim it and dispose of it properly. Its not without risks. Our building codes are pretty rigid as well, its a big pain point.

New HVAC install is gonna need an electrician, the lines pass through walls allowing the possibility of condensation to produce deadly mold. Every installation needs individual consideration. If it isnt %100 perfect, the customer will be riding the installer's ass.

The US has is a Safety Above All mindset on some things. We improve safety far beyond economic rationality because we don't want to systematically kill each other in this way, however few that is.

Unrelated example: a national EMT outfit operating here made all their techs wear plate carriers and ballistic plates. There is nearly no gun violence here. All the techs stopped carrying the plates after a few months because its dumb, and wont stop a baseball bat or a knife, but this is a national outfit, surely they did a cost benefit analysis. Someone signed the check and wrote a policy to make them wear em every day. Plates expire, also.

That said, we can definitely do better, and the cost is too high. Installers are in demand, and we tariff the imports to the tune of %15-%30.
