I realize similar questions are on here, but I haven't seen anything addressing my situation precisely.

I had a new gas furnace installed over the summer. This winter we turned it on and gas smell filled the house. I thought maybe that was normal the first useage.

But over the last couple weeks, a minor gas smell still comes out. Sometimes it's more prevelant than others.

My CO detector is almost always at zero, but pressing the "history" button reveals it's been to 25 in our upstairs bedroom. *Most* of the smell is in the downstairs kitchen when the heat kicks in.

I called my gas company today and they'll be out Monday morning.

My concern is when I had a problem previously with a gas smell, they said it's just a backdraft due to an outside wind, even though we'd experience the smell on non-windy days.

My concern is they'll chalk it up to that again and not fix anything.

(they've cleaned everything in the past btw)

What thoughts or suggestions do you have?

Should I expect to come home to a gas smell in our house? What can be done?

Thank you.
