cost to redo ductwork...wow!
I had the third repairman out to see why my ac isn't cooling (it got to 82 inside recently). He said that it is working as well as can be expected after doing all the measuring of temps coming in and going out, etc. He recommended that the duct work in the attic be completely replaced for better efficiency. He seemed very capable and had us try some easier fixes first such as sealing the attic door better and blowing out the insulation that was obstructing the attic vents. None of that helped. His quote though was vague...somewhere between $3-4,000. That seems rather high and I don't like the broad range. Any advice please??? Oh, we live in Houston and it IS really hot here!
