The air conditioning is an expensive idea. Your 2 units are rated at 800 Watts each. Your power supply's likely will be 90 percent efficient maximum. So we are talking a total of 1760 Watts. Remember this is all being converted to heat. The online calculator suggests 6000 BTU air conditioning to keep the room at ambient (or break even point cooling equals heating)
A 6000 BTU air conditioner is going to be approximately 700 Watts.
So your total power consumption is close to 2.5kW per hour, 24/7.
Please do keep in mind what your household circuits are rated for. For example circuits here are a maximum of 1800 Watts.
120V x 15A = 1800 Watts
They do need to be derated though for 24 hour use.
1800 Watts x 0.85 = 1530 Watts
As you can see you would require 3 separate circuits so you don't exceed the derated value ( so you don't accidentally start a fire) if you have 120VAC.
At my house I ended up making a 80 foot extension cord with 8 guage (4 wire) that plugs into my dryer plug. On the other end I build a splitter box with four receptacles (each fused at 15A). Very safe.
