Water and Ice on Windows

duluthjeff

We are experiencing more condensation and ice buildup on our windows than in years past. 4-year old 2900 SF very tight, well insulated home in Duluth MN. Running a Venmar HE 1.8 HRV at full blast continuously. Windows are well sealed, double paned low-e. This year, we are getting more condensation and icing whenever the outside air temp is Is our HRV too small, or am I doing something wrong? We are not generating more water into the air (cooking showering etc.) than in years past. Any ideas?
