This is why I chose to replace my basic forced air gas furnace and basic 16 seer single speed single stage A/C unit with the same thing. Every part on these is relatively simple, largely serviceable and every parts house coming and going will have something that fits. I disagree with others that any of the more fancy stuff is any more reliable (and Dad worked as an HVAC master tech for a long time and also agrees with this) and I can't believe people pay for more complicated stuff when so far as I have ever seen it's 90%+ snake oil and drives the initial price and the cost of repairs up astronomically, and largely cools or heats the house all the same. I am well aware that Bryant, Lennox, Trane, Mitsubishi and everyone else coming and going has got the more complicated garbage that talks something more complicated, I just really don't get why you'd double or more the cost of things when you can get something that just works for less. I also don't understand the obsession with "smart" controls on any residential single family home when a basic programmable thermostat already does basically everything.

I'm sure as everyone piles onto the mini-split hype train, there's going to be even more fleecing of homeowners for maybe middling quality hardware and installs. Someone (either the HVAC company owners or the hardware manufacturers or maybe both) is making an absolute killing on this; maybe it's time for a career change.
