Do heaters make banging noises?
Typically, when a heater makes a loud banging noise when it turns off, it’s the sound of metal contracting. As the furnace cycles, air is pushed through the duct system into your living areas. A dirty filter restricts airflow, causing warm air to back up in the system.
Why is my electric heater making a rattling noise?
Rattling. A rattling sound coming from the furnace can indicate a loose panel or a loose screw. If it’s not a loose screw, it could indicate a leak or crack in your heat exchanger, which can be very serious. Faulty heat exchanger can leak dangerous (and potentially lethal) carbon monoxide into the home.
Why does my water heater make a knocking noise?
The noises are often in the morning or evening. In Sarasota, the most likely reason for random banging noises when there’s no water running is sediment buildup in your water heater. It can be loud enough that the reverberations carry and make it seem like the knocking noise is coming from the pipes in the wall.
What kind of heater does not make a clicking noise?
Generally, the most silent heaters are infrared heaters or oil-filled radiators. While both of them can make a clicking noise here and there, they only do them seldom. While they’re heating they don’t make any continuous noises, because they don’t have any noise-producing parts like built-in fans.
Why does my air conditioner make a clanking noise?
Clanking is another sign of a loose or out-of-balance part. The parts inside the sealed unit have likely failed, and the compressor itself may have become loose, possibly necessitating a replacement. This sound can also mean that the indoor blower or outdoor fan and its blades are out of balance and hitting other parts.
Why does my furnace make a loud noise when I turn it on?

Why does my heat exchanger make a clicking sound?
Heat exchangers are made out of metal. Over the years the constant heating and cooling off of your heat exchanger can cause cracks in the metal. The clicking sound you hear could be the metal in heat exchanger heating up the cracks and they start to expand a tiny bit.
Why does my forced air heater make a noise?
Forced air furnaces are highly efficient heating systems that can quickly and evenly warm-up a house, but they also double as a central air conditioner in the summer. Due to the dual jobs they perform though, the many composite parts that make up these systems can cause noises throughout the house as heat travels up through the registers.
