Since I now have had 3 different contractors over to give bids on replacing my 2- 20 yr. old systems ( a 3 ton & 4 ton)
Not ONE offered to do a Manual J( even though it is required for the NJ state rebate) -Do you think I should have a door blower test done and what exactly does it show?
Should I have an outside consultant come over and do the manual J and the door blower test-Since the house is 20 yrs. old- If so how do I go about finding such a person and how much approx. should it cost-Since we are going to be here a long time I want it done right- Everyone just asks are you comfortable now and then says just replace with the same size- Also a side question- The flex tubing from the handler to the ducts are starting to peel showing the insulation under it- 1 guy said you need to replace it and the others did not even mention it- Should I replace the flex tube or is it OK to have the insulation showing??- thanks for your help and sorry for the long post
