Is $4,200 to replace ductwork with R6 flex a fair price?
Project Details
I had an AC leak that caused water damage and mold. An AC technician advised that duct cleaning would not be sufficient due to extensive mold and breaks, suggesting replacement to prevent spreading. I have hit my $10,000 insurance cap, so this replacement would be out of pocket, but I am immunocompromised, making this a priority. My house was built in 1968, and I moved in two years ago. Multiple AC companies have noted that the previous owners did not maintain the HVAC system well, leading to worn, old, and dirty components. Another AC technician confirmed the need for ductwork replacement, though he did not believe it was mold.
