My 20 year old ranch home had a direct vent 90% furnace and a lifebreath HVR as an initial install.After a few years the HRV stopped draining any water from the house and I had to install a humidifier to get some humidity in house during the winter. House is pretty tight(above average according to energy audit's door fan test)
Just had a new Trane xv95 furnace installed and they balanced the HRV, the outside temps are around 70 right now with high humidity and still nothing from the HRV. The intake and exhaust vents are strong draws and exhaust but there seems to be very little draws from the return registers for the HRV from bathrooms and laundry room.
Anyway the fan on the HRV is a bit noisey so after 20 years I'm thinking of replacing the unit or just not using one at all. Could the core just is not passing enough air through?
Unfortunately not a lot of experts around here to help. Appreciate any from you guys.
