Yep, mine was like that on my old HRV installation. The after the fact fix was to change out the insulation and really make sure the new stuff was taped off well from the in house air. Also, your HRV will probably have a feature that switches to inside air when the unit begins to freeze up from bringing in too much cold fresh air.

For your install, add a loop to the condensate tube. This keeps the HRV from drawing air from the end of the tube, which is usually sitting on the floor near the stinky floor drain.

Here is mine.
