Let me introduce you to the Certificate of Need.

If you want to open a new hospital or facility like this in a town, you need a Certificate of Need from the Department of Health in your state. This ostensibly shows that there is a need for your facility because it is underserved. In actuality, it asks your competitors to say whether they'd reduce services or close beds if you opened your facility. While there is some community research etc., a lot of it comes down to "do your competitors think they can stay profitable enough if you open up shop?", and if they don't, no CoN for you.

It's not uncommon in more rural areas to find a business that is essentially "more than an urgent care but less than an emergency room". e.g. they aren't doing trauma surgery but they can deal with broken limbs, severe lacerations etc that an urgent care couldn't handle.

My point is that while it's true that there are "step functions" in certain services, this is not always the case.

Maybe if you’re talking about the small residential market, that’s not where the money is.

The large HVAC/Electrical/Plumbing contractors in my area all perform their own work, including the one I work for. Large contractors do commercial and industrial work, not service calls for homeowners. Doing service calls homeowners sounds like a nightmare, personally.

Bain Capital just bought Service Logic which is a holding company for HVAC contractors. They own a couple of the local HVAC shops and they all have their own PMs, sales, estimating, and field staff.

If the market doesn't reward this then maybe quality isn't important to the customer. Could be price, location, availability, etc. - PE can absolutely create that value even when they roll up 70% of your local HVAC market.
