You shouldn’t be able to smell your home heating system. The most imperative thing: if you smell gas, turn off the heating system, open some windows and call your power company right away. The last thing you want to ignore is a potential gas leak, which could cause a fire. Better to have a power company technician check it for your safety. If your Harrisburg, Hershey, Carlisle, Middletown and Palmyra area home fills up with a dry, dusty smell when your heat comes on, the first thing you should do is change your furnace’s air filter. That dusty smell is just the furnace burning dust out of the filter. A clean filter allows the unit to run much more efficiently and cleanly. The owner’s manual that came with your furnace (it might be stored in a little pocket right on the furnace housing) should include instructions on how to do this, but if you’re uncomfortable with it, call in a licensed CROH Heating & Air technician to show you how. If the dusty smell persists, have one of our Heating & Air technician inspect your home heating system. That odor could signify a bigger problem that could get expensive and dangerous if left unattended.
