The only way t be exact is to do what is called a Manual J load calculation.It is a program where you enter all of the building construction factors such as square footage of home, construction type such as wood frame or brick,how much attic insulation, wall insulation. whether on a slab or up off the ground on peers. the square footage of glass windows and type of windows facing each direction, whether there are covered porches shading windows,number of occupants(figuring 2 per bedroom),number of fireplaces if any, number and type of exterior doors,ceiling types,geographic location and other such factors.For example a 1500 square foot well insulated home with double pane windows on a slab with 8 foot ceilings and very few windows facing east and west (receiving direct sunlight) with 2 bedrooms in North Carolina with an average high summer temperature of might 85 require only a 2 ton unit to properly cool the home where as the same1500 square home in South Alabama with an average high of 95 degrees.with 9 foot ceilings or if not well insulated and had a lot of glass windows facing west or east may require as much as 3 tons to properly cool the home.But as a rule of thumb in Linden, you will probably need between a 2 and 2.5 ton unit. The average cost is going to be between 1500 to2000 per ton for equipment installed and if you need ductwork, another 1500 to 2000.You will want to get at least 3 estimates from reputable contractors in Linden. Prices are going to vary by brand as well as company's overhead.For example you can get a small company with only 2 or three employees to do for as much as 1K cheaper than a large company with 2 or 3 people sitting behind desk answering calls.I good estimate would be between 4000 to 4500 for equipment and around 6 grand if you need ductwork.
