Strange noises coming from your HVAC ducts can be frustrating. To eliminate them, you should determine the root cause of those sounds. In this blog post, trusted AC service provider EZ Air Conditioning and Heating discusses the common causes of ductwork noise.
Duct Expansion and Contraction
As your HVAC system heats and cools your home, the ducts may expand and contract. This is normal but can sometimes result in popping or creaking noises. Ensuring proper insulation and secure connections can help reduce these sounds.
Air Pressure Imbalance
If you’re hearing whistling or humming noises, it could be due to an air pressure imbalance in your HVAC system. This issue can be caused by blocked vents, closed dampers or an improperly sized system.
Animal Infestation in the Ducts
Noises like rattling or banging can indicate that something obstructs the airflow in your ducts. Usually, a roduent or bug infestation cause the sounds from HVAC ducts. If you notice droppings or other signs of infestation, schedule pest control services to diagnose and address the problem.
Moreover, to make ductwork less appealing to animals, get your ducts cleaned out regularly by your HVAC technicians.
Loose or Damaged Ductwork
Over time, ducts can become loose, damaged or start to separate at their connections. Any of these problems can lead to air leaks and a variety of noise issues.
Oftentimes, loose or damaged ductwork is a result of improper installation. This sagging or bending of the ducts makes it harder for air to move, leading to increased static pressure and noise generation. To avoid ductwork problems, make sure to hire an experienced contractor when having your HVAC ducts installed.
Dirty Air Filter
Clogged or dirty air filters can affect the movement of air in your HVAC system and cause noise. That’s why HVAC filters should be cleaned or replaced on a regular basis. Moreover, it’s best to schedule a routine duct cleaning services to avoid debris buildup that can restrict airflow.
