This summer, I upgraded my walls to R20, attic to R40, replaced metal single windows with double low-e argon vinyl, replaced all wood doors with insulated steel, air sealed the house and replaced a 30 year old 120k gas furnace with a 75k condensing unit. The old furnace used to run every 5 out of 15 mins at 0C, now it runs 10-15 mins every 3-4 hours. Something doesn't seem right here as my neighbors runs 2-3 times per hour and it's a 100k furnace in approx the same sized house with similar insulation (maybe 20% less) I have my tstat set to +/- .5C and CPH disabled.
