I have a 2600 sq ft split plane, 1650 up 950 down. The attached garage is on the lower level. The furnace and evaporator are contained by the garage. the condenser is outside. I have raw gas forced air system beside duct work. On the upper floor the vents are within the floor, on the lower level the vent are in the ceiling.
Answers:    You will requirement minimum 4 ton to 5 ton unit. Expect to income at least $500 to $600 per ton for the component and $800 to $1000 for install. Now here is the thing - you procure what you pay for - you can perceptibly pay much more. The one point as a homeowner you need to research bar the quality of the part you want and it's warranty - but as important -is how long have the installer been surrounded by business/will be in business. Good luck...
