We don't do any type of work on homes - only inspections. I would suggest contacting an HVAC contractor to service your HRV. It sounds to me like the defrost cycle on the HRV isn’t working properly.

I cleaned all the filters in the fall, and I'm wondering if I screwed up the balancing. Generally only develops on colder days, obviously. I also do not notice a lot of condensation hitting the pan. Is this frost on the outside of the duct a symptom? What would a rebalance and general inspection of the HRV cost?

What would a rebalance and general inspection of the HRV cost?
