If we were to add vents in the ceiling to connect the utility closet to the
attic, to get fresh outdoor air from the attic, would we have to worry
about insects entering via those vents, and extreme hot and cold weather?
For example, if in January a cold draft comes down the vent, enters the
main living area of the house, and triggers the thermostat, it could cause
the heater to run more than it otherwise would. Right?
