Sadly, this is seldom the case for heat in Ottawa. Often it can be 32C, 35C, with 80%, even much higher humidity. Seeing as it was -30C a mere 6 months ago, and many Canucks think 15C with sun is a nice temp, comfort comes at close to 20C. Which of course, with the sun pounding on the house, means you need the return air to be 10C or some such.
