Modern air conditioners are functional, aesthetically pleasing, and almost entirely silent. If you do hear a strange noise coming from the unit, it could signal a serious issue. As Newport, KY’s, premier HVAC contractor, Arc Electric & Air Conditioning & Heating handles the community’s heating and cooling needs year-round. Below, they share five troubling AC sounds to be mindful of. 

HVAC Contractor on AC Noises You Don’t Want to Hear

1. Loud Banging

Banging signifies a serious issue, so if it persists, contact an HVAC contractor immediately. Vital compressor components are probably broken, such as the connecting rods that keep it in place. Parts like these are sealed firmly, so if they’re defective, you need air conditioning repairs ASAP. 

2. Nonstop Buzzing

Buzzing is irritating, especially when you just want to relax and cool down. Stop the hassle by calling your air conditioning contractor for an inspection; this noise could stem from an array of issues, but they’re usually a quick fix. Built up debris is a common cause, along with dirty condenser coils and air filters. If all you need is an air filter change, a professional will get your unit back up and running in no time.

3. Repeated Clicking

The only time you should notice a clicking sound is when you turn your unit on and off. If it continues, a failing thermostat is likely to blame. This is an issue that requires immediate attention. A bad thermostat could lead to blazing temperatures indoors. Not only is this uncomfortable, but it’s also dangerous for those with breathing problems, causing a stuffy interior environment. 

4. Light Humming

While humming is never a major problem, it isn’t something you should ignore. Loose parts can vibrate inside your unit, creating the light hum you hear throughout the day. An air conditioning contractor will evaluate the unit to discover what’s wrong; it’s best to tighten parts quickly to evade a more serious problem.

5. Piercing Whistles

Loud, piercing whistling and screeching are far more than a hassle; they require emergency care. A refrigerant leak is the most common cause, and allowing the fluid to spread inside your unit could destroy it completely. The most dangerous effect, however, is refrigerant’s impact on human health. For those with heart problems, prolonged exposure could cause cardiac arrhythmia or palpations, so call a professional ASAP.
