I've got an air vent from the outside which discharges right next to the furnace. I know the furnace needs this air, but a glacial breeze comes through all the time. I've found 3 options and I'm not sure which to do:
- Extend the vent until its about 6" from the floor and put it in a 5 gallon bucket.
- Add two elbows to make a 180 degree turn and extend it up 2 feet or so.
- Do nothing. I'd be crazy to try and change something that's been like this for the last 20 years.
Will option 1 or 2 actually help? I'd prefer option 2 because its the more compact solution.
