A HEPA filter would be far too restrictive for a portable air conditioner. Use only the filters that are specified for the a/c. If you want to HEPA filter the indoor air, then use a separate device designed to do that.

The current rating has to refer to the peak demand, most likely the startup current. The 14000 BTU unit might start the fan and compressor at the same time while the 34000 BTU unit manages the startup current to something reasonable, like a soft-start. When it comes to the average power consumption the 34000 BTU unit has to consume more. Maybe the average ...

I would replace a 15 year evap coil. Since the efficiency of the condenser/compressor has changed (more efficient), you also need to match it with the proper evap coil and metering device (TXV).

According to this website, "Air circulation saves energy year-round by reducing the need for space heating and cooling." If your goal is to even the temperature throughout your home (opposed to creating pockets of relative heat near the ceilings and relative cold near the floor), the more air you can circulate (by increasing your fan speed), the ...

In a word, efficiency. A variable speed motor can operate at a slower speed when less cooling is needed. Lower speed means less power used, which saves money.

Option 2 is probably not an option at all - that setup is almost always for a special-rate storage electric water heating tariff and is only on for a few hours when demand is low overnight (which is why it's a special lower rate) or else it's switched off whenever loads are high (a different scheme, similar concept.)
For my utility, you can keep them if you ...
