The cost of new ductwork for a 4-ton unit serving a 1,900 sq ft area can vary widely based on materials, labor, and local market conditions. Generally, you might expect to pay between $1,500 to $3,500 for flex duct installation. Factors such as the complexity of the installation and any additional modifications can influence the final price. It's best to get quotes from local HVAC contractors for a more accurate estimate.
Flex -VS- Ridged ductingThere is not a better or worse as far as flex vs. ridged. There is however a better or worse application of each. Flex duct was designed to be used as a �Last 6 Feet� connector for drop ceiling applications. For this purpose there is nothing better. It also works great for multi radius connections over a short length (6 ft or less).Ridged pipe is much better suited for longer, straighter runs. The pipe is much less restrictive and has a lower friction loss due to its smooth interior.The ASHRE Design manual has great information on use of ducting materials.Flex has become the materials of choice for ducting runs, only because the installers have become lazy and the company owners have become greedy. The installation cost is reduced because there is little or no time spent measuring and cutting duct to fit the application. Flex can be strung through rafters, over and around perlins, and comes in 25 ft lengths (shorter than most runs) reducing cuts and splices. It can also be strung too tight, smashed and bent to unreasonable restrictions and seldom if ever properly supported.If used properly, flex is better than hot buttered toast. Done wrong, and reduced airflows, extreme temperature differentials and overall poor efficiency is the only possible outcome.

Flex is a measure of how bendable the stick is, the flex has nothing to do with left of right handedness. For high school players the standard flex is 85, with some of the stronger players using 100 flex. You want a flex that is going to allow you to get as much snap as possible when you shoot. The lower the flex, the easier the stick bends.
