I found water, or liquid leaking from my gas furnace. What can this be? Recently we had a repair man come, he replaced an igniotor. The furnace is 7 years old. HELP!

If this is a 90% furnace it produces condensate which should be plumbed to a appropriate receptacle. The leak should be investigated and repaired because it can cause rust or corrosion. Good luck, Mike

I agree with acetc. You can check all of the rubber drain lines inside the furnace the tech may have hit one while making repairs on the furnace.
