Cleaned filters on ERV and tested operation of ERV system. Treated ERV condensate drain. Everything runs normally at this time. Recommend cleaning of minisplit systems in spring. Talked with Kevin about addition of a whole home dehumidifier to system - will not be able to tap into the ERV but would be able to add one potentially in crawlspace and duct in a return and supply to help address moisture issues. Kevin gave a rough estimate of $4500 but said to call and schedule an estimate so he can give an exact price.
