My dad bought a failing HVAC business 30+ years ago, then made it profitable over the years and sold it back to his employees last year. He had the option to take a few highly lucrative PE deals, but it was clear they would squeeze the life out of the employees and customers he had worked hard to support over many years. I can’t imagine how low quality this kind of trade work will become if PE owns them all. It will be similar to vet, dentist, and dermatology clinics which now feel like factories that don’t care about the humans on the other end - often employing fear tactics and sales quotas to incentivize upsells.

This already happens. The most common AC repair needed is a new capacitor. It's a $20 part.

Call your dad's business, you probably get a quote for $100-ish and it's fixed in ten minutes.

Call a PE owned shop and they are likely to tell you that your entire system needs replaced. Quote $5-$8k.

Reports like this are already common place, and the roll-ups of former small-businesses in industry like HVAC that the PE people celebrate will only make this worse for customers.

Could someone ELI5 why AC capacitors are so fragile? I had one fail last year on a unit that was just out of warranty.

It’s not so much that they are fragile, as they’re a part that gets a lot of very heavy duty use and they’re expensive to make invulnerable. Ain’t no residential customer going to pay for a 100mfd 240v tantalum cap (how big would it be even?).

Think of them like a car starter motor or transmission (for old ICE vehicles).

Assuming we’re talking motor start capacitors anyway. For most of them, every time the compressor starts they see a dead short at 240v for a couple milliseconds, typically in the 10,000+ amps range.

And most people use their AC the most when it’s hot and nasty out. Which doesn’t help.

By "mfd", do you mean µF? I have some basic knowledge of electronics and am not familiar with "mfd" in this context but assumed you must mean microfarad.

Apologies, yeah most motor start caps for some reason use mfd to mean micro farads. [https://www.packardonline.com/electrical/capacitor/motor-sta...]

I guess from before the days of Unicode?

µF == the same thing, but tends to be the ‘more correct’ modifier used in electronics and engineering, rather than industrial parts supplier catalogs.

Oh, wow, this is so bad. m usually means "milli" not "micro". At least they could have used u instead of µ, which is a more common replacement when you don't have the keyboard character available.

Just wait until you see the actual dimensions of a 2x4!

I owned a house once that was balloon framed, with 2"x4" black walnut studs in the walls.

They just don't make things like they used to. :)
