Is $6,000 to install a whole home dehumidifier setup for the attic a fair price?
Project Details
I've had several AC guys out to investigate why my air handler is sweating so much, and they all say it's due to poor attic ventilation. I've already had all insulation replaced and made sure the soffits weren't clogged. The issue is primarily with the downstairs unit, though the upstairs has some condensation around plenum/duct connections. I believe the humidity from the sweating is affecting the entire attic. I've placed a hygrometer in the attic and a portable dehumidifier draining into the pan to monitor and mitigate. Both AC units are less than 3 years old and are kept at 72/73 degrees. The original installer refused to work on it due to microbial growth, blaming poor ventilation. Inside the house, it stays 45-52ish with a whole home dehumidifier and four portable dehumidifiers in each bathroom. We've previously had to rip our house apart and put it back together due to mold from the previous owners.
