What does ventilation (erv/hrv) involve in Wilmington?
A ducted ERV or HRV typically costs about $2,500 to $6,000+ in an existing home and about $1,800 to $4,500+ in new construction. In Wilmington’s humid summers an ERV is usually preferred because it also moderates incoming moisture. Energize Delaware lists ventilation equipment rebates of about $400 to $600.
