Will this cool 1,200 sqft with two 10ft doors?

Yes this unit can cover that square footage. Generally, anything above 30,000 BTU can cover this square footage. However, many factors play into sizing such as geographical location, insulation quality, etc... Given there are 10 ft doors/ceilings this 36,000 BTU unit should be a great fit. If you have any further questions please feel free to give us a call! Thank you.
