If It weren't for the HVAC licensing gangster system where armed police would show up and stop me, I would absolutely start a company ripping out whatever broken system you have and with the business model is I would replace it with a small menu of mini split systems I have goons trained to install for cheap. There is massive pent-up demand for this. Even poor people fix their HVAC system if they have a spare buck. I recently met an elderly lady (yard sale to pay her HVAC bill) who paid $15k, her hearing was shit and she seemed about dead, she wouldn't have given a single shit if it was a little louder. But in any case, I've installed many Daikins (for myself) and for not much more money they are as quiet as the sound of the moving air.
