Working with my dad to address HVAC concerns

It took him twenty years to decide to paint the inside of the house, since he told me that his ancient paint was still covering the walls just fine, when he finally made the choice to replace his ancient heating plus cooling system, it was only because the whole thing stopped finally working and bursted into flames in the furnace room of his house, he waited until he was going to need to replace the entire thing before he finally did it, then and now, with his new Heating, Ventilation plus A/C system plus new paint, I keep telling him that he should really go ahead plus replace the a/c plus heating vents in the house, but the air conditioner vents plus heating registers in his cabin are so rusty and worn down that they make the whole venue look rundown plus unlived in

My amazing father is 1 of those guys who always says that if something isn’t broken, then you don’t need to patch it up, however I agree with him to a particular point, however when it comes to my fathers place, I suppose he could make an exception or more than one.

I told my dad this and he just said that the air conditioner plus the heating runs through those air vents just superb plus so it doesn’t matter to him what they look like, but no matter what I say about it, he refuses to spend any money to get new a/c plus heating vents, periodically I just don’t understand my dad and his unwillingness to make his cabin look nice or spend any money unless he literally needs to.
