I plan to upgrade my attic ventilation from the current two end gables to a ridge and soffit vent system. My house is a two story colonial in Maryland.
Will I notice any effect on the temperature in the second story inside my home? I have R38 attic insulation already but it is still a few degrees warmer than the downstairs temperature. I haven’t heard anyone claim that it improves the indoor air temperature but it seems like it would.
