I do high end construction and installed them for homes costing dozens of millions in very humid climates.

That is the problem.

A technology that only serves the rich (because they are the only ones that can afford to "have it done right") is exactly what the elites want--for themselves.

Good practical technology is close to idiot-proof, because there are so many idiots out there...

Heatpumps can be put in for little or even no additional cost when replacing AC. I’ve done them for some of the lowest end projects as well.

The biggest deal is doing the correct calculations and picking the right equipment for the job. It’s 5th grade math but most people simply don’t take the time to do it.

Of course it’s definitely more idiot proof to slap in a 200% oversized gas heater and call it a day. You save a few hours of math but lose much more in equipment, materials and energy. For this reason many cities are now mandating engineering of any new HVAC
