I had Harvey windows with argon and low E glazing installed in April, in CT. now thats its gotten colder I've noticed some condensation on only a couple windows. Its about 1/4" along where the top and bottom window meet (above the window locks) and the bottom window above the handle lip. The seals appear to be fine. Someone suggested to turn the heat up, the rooms may be too cold inside and the sun hits the outside. Any other suggestions before I call the installer? thanks
