1800watts of led's in a 18x18x8' sealed room... think I will need an A/C?

If you're running it sealed you will need to have a solution to fix humidity, especially if you're burning co2 as well. Dehuy will add some heat to the equation but also remember you want temps around 80ish; it's generally a question of how to get the space hot enough rather than cool it in our led veg.

That’s what I was wondering lol. Abviously not 18x18 of canopy.
Yeah, it would be hard to move around. 
Lots of variables involved like the climate, insulation and construction of the room/building etc. Some means of temp control will be needed, heat, AC or both. I'd put 1800 watts in there with space heaters for a couple days and monitor temps.

Correct, canopy is only 5'x15'.

Yes plan to keep temps around 84 and humidity high. I will through a dehumidifier in the room or maybe hookup an exhaust connected to a humidistat. I do this in my sealed flower rooms that runs burners. Its kind of like a fail safe just incase the burner doesn't combust properly. Also helps the dehumidifier when the lights go off. We shall see but definitely have to come up with a plan for the humidity.

I know 3.41btu per watt of power. What I don't know, and which calculators dont factor in, is ambient temps and room sizes. I've never ran an led before so its hard for me to judge but my gut is telling me I don't need A/C.

You're right, you'll need some oxygen to be able to burn co2, my bad for not thinking about that. What lights do you intend to use? Wattage is a good indicator of how much heat you'll get but some LEDs seem to heat up more.
Another thing to maybe keep in account is how co2 affects the stomata, transpiration and hench how much your plant is drinking. Higher co2 tends to close the stomata which means less drinking, we went thru a few shitty veggs to learn that one but we were using gas heaters with no co2 level control.
