Joseph, a 2400W Honda will put out 20 amps, which may trip off if you tried to power a small AC unit, a large chiller, and a large circulation pump at the same time. One way to deal with this is to run the loads in cycles. For instance, run the AC for two hours, then run the chiller and pump for two hours, etc. You can get "portable" gas generators up to 4000W (33 amps) and bigger, but these are getting to be fairly big generators.
If you wanted to run a whole house AC unit or heat pump, you'd probably need a fixed generator hard wired into the house electrical system through a bus transfer. You need to draw a permit to install this type of equipment. I would also consult (and use) an electrician, and be sure to get a generator that can handle the starting load of the compressor without tripping off.
But none of this does you any good if you aren't home. In that case (Sniper's case) you must either have someone tend the generator for you or have a generator with an autostart feature and an automatic bus transfer.
