: I don't know if this is applicable to plumbing, but everytime my furnace kicks on there is a whistling noise. It is getting extremely annoying. I wanted advice before I call someone. Plumber or heating/cooling? Thanks!
You may be able to do this yourself. When the furnace comes on(or if you have a manual fan switch on your thermostat turn it on) go in search of the noise...good odds it's just an air leak in the duct.Then you will be able to use something for which it was originally intended...DUCT TAPE !! Good luck pipewerks
