Why Is My AC Making Loud Noises?

If you live in the Steger, Illinois or Crown Point, Indiana areas, you know summer means heat and humidity. Being without an air conditioner isn’t really an option, not if you want to stay cool and comfortable inside your home. 

There are a variety of issues that may result in a noisy AC. If your air conditioner is loud or making unusual sounds, it’s important to discover the source, so the issue can be addressed as soon as possible to prevent further damage and ensure your system is running efficiently. Here are some possible causes of a noisy AC:

  • Dirty or clogged air filter: A dirty or clogged air filter can cause your AC to work harder to circulate air, which can lead to loud noises. Regularly replacing your air filter can prevent this issue.
  • Loose parts: Over time, parts inside your air conditioner may become loose or worn, causing rattling or banging noises. Loose or worn out components also affect efficiency, which can increase your energy bills.
  • Faulty fan blades: If the fan blades in your AC unit become damaged or bent, loud clicking or banging noises may occur. Since a malfunctioning fan can affect airflow, schedule an AC repair right away.
  • Refrigerant leaks: A refrigerant leak can cause your AC system to make a hissing noise, as well as reduce the cooling capacity of the system.
  • Electrical issues: A normal functioning air conditioner will naturally have a slight humming sound. However, electrical issues may cause unusually loud buzzing or humming noises, which should be checked by trained professionals. Call Merts Heating & Cooling for an appointment. Merts will diagnose your problem and complete an AC repair quickly and efficiently.
  • Frozen evaporator coil: If the evaporator coil in your AC unit becomes frozen, it can cause loud popping or cracking noises. This can also reduce airflow and efficiency.
  • Age of the unit: As your AC unit ages, it may start to make more noise due to wear and tear on the parts. Merts Heating & Air Conditioning has trained Comfort Specialists who are able to assess your current AC system and offer affordable solutions to keep you cool all season long. 

If your AC is making loud noises, it is important to have it inspected by a professional HVAC technician. Regular maintenance and inspections can also help prevent these issues from occurring in the future.
