Many homes today are heated by a furnace. They’re more energy efficient than ever, they make your home comfortable and they are widely available. However, they can sometimes develop a problem. If your furnace has started to make a whistling sound, what is causing that?
Dirty Air Filter
A dirty air filter can produce a whistling sound. As it gradually gets clogged with dirt and debris, it has less space for air to pass through. Additionally, a clogged filter makes your furnace work much harder than it should, which leads to breakdowns. Check the air filter monthly and replace it as needed.
Leaking Air Ducts
The problem may not be your furnace. Most air ducts in homes are leaky. Holes and gaps in your ductwork cause unnecessarily high energy bills and can let in rodents. Air can whistle when it leaves these holes and ducts.
Natural gas has ethyl mercaptan added to it as otherwise it is odorless and tasteless. Ethyl mercaptan smells like rotten eggs. If you smell this near your furnace, turn off your furnace, leave your home, and call an HVAC company for heating repairs.
