: Our furnace keeps on making a banging sound as it comes on. Does this mean there is something
: wrong with it and should we be looking at getting it replaced?
The burner unit bangs or booms when it kicks on? It doesn't need replacing,just a good cleaning and tuneup. The nozzle isn't spraying the fuel correctly and is leaving unburnt fuel after shutting off. When it fires up next time,it's not only igniting what it's spraying out,but what was left in there from the last time. That's a potentially dangerous situation. The sooner you get it done,the better.
