I have the same A/C setup in my own 1600 sq ft house. I've been happy with mine, nice and quiet, cools well. I got the 'thermalzone' branded equipment which is essentially the same thing but the house brand at our supplier. Very large condenser for a 2 ton, larger than my neighbors 3 ton AC. Lots of coil surface area for high efficiency. The AC and blower combined uses about 2,000 watts according to my whole house power meter. Didn't replace the furnace on my setup.
