What’s That Sound Coming From My Mercersburg, PA, Furnace?!

December 30, 2021

There are multiple things that might cause your furnace in Mercersburg, PA, to produce louder noises than it should during normal operation. If your furnace is producing unusual noises, it is important to identify where they’re coming from and whether it is just a normal sound or is a sign of an issue with your heating system. The following are some strange noises you may encounter with your furnace and what they mean for the state of your equipment.

1. Banging Noise

You may hear a loud bang shortly or immediately after you start your furnace, which is a sign of a faulty ignition system. Several factors can affect the gas ignition in a furnace, among them being dirty or clogged burners. Professional HVAC technicians will resolve the issue before it escalates to a bigger problem and perform necessary HVAC maintenance as well.

2. Furnace Whistling

If your furnace starts producing funny sounds that resemble whistles, it means the air is likely blocked. Other things that may cause your heating system to produce whistling noise include strange objects in the ductwork, closed vents, blocked damper, or return. You can solve this issue by cleaning the ducts, filters and returns, as well as opening up the vents and dampers.

3. Rattling Ducts

In most cases, rattling ducts are not a cause of concern, as they do not indicate any significant issue with your heating system. More often, rattling ducts may result from loose duct joints, which may be releasing heat. In other cases, the duct might be smaller than the vent opening, which causes it to move back and forth and rattle as air blows through.

Regular furnace maintenance will go a long way in preventing many of these sounds in your Mercersburg home. Schedule an annual tune-up for your furnace with trusted HVAC experts. Call Leckron’s Comfort Solutions today and we will help you with all your heating needs.
