Sounds You Should Never Hear from Your AC

Most home appliances have certain sounds that they make while they are in use. Typically, homeowners become so accustomed to hearing these sounds that they don’t even notice them after a little while.

However, if a major home appliance, such as your AC unit, has started to make a strange noise, it’s typically cause for alarm. Read on to find out whether the sounds you’re hearing mean that it’s time to seek out AC repair in Sterling Heights, MI.

Common Sounds Caused by a Faulty AC Unit

Not sure what to think about the sounds coming from your AC? Here are some of the common noises that homeowners have experienced and what they might mean.

Bubbling or Hissing

If you’re hearing a high-pitched hissing sound or a low bubbling coming from your AC unit, you’re most likely hearing the effects of a refrigerant leak.

When AC systems are installed, they contain enough refrigerant to support the unit throughout its lifespan. Therefore, if a leak is occurring, it’s a sure sign that your AC’s functionality has been compromised. It will likely get worse and worse as the leak continues.

Buzzing or Banging

A buzzing noise from your AC is usually caused by an old or malfunctioning blower motor that is working at an inconsistent or slow speed. A banging noise could be a sign that a component within the unit has come loose, such as a piece of wiring or fan blade.

An HVAC technician can help you to pinpoint exactly what might be making these sounds so that you can decide what the best course of action is.

Clicking or Screeching

A clicking noise is relatively normal when a unit is first starting up, but if the noise continues during normal operation, it may be a sign of a defective component. A screeching noise is usually due to a build-up of excessive pressure within the unit’s compressor, which can be potentially dangerous and cause further damage to your AC system.
