How To Handle The Strange Sounds Coming From Your HVAC Unit

Common AC System Noises: How To Handle Them

AC Man Houston | AC Noises in Houston TexasThanks to the ever advancing technology, air conditioners are more efficient and very silently. As a matter of fact, some of the newest models can run without you noticing they are even on. Nevertheless, the units still produce some sounds such as the initial click with switched on, or the humming sound when at a higher setting.  While some of the sounds produced are considered normal, it’s advisable to keep an ear for new/strange noises from these systems.  Some of the strange noises may be an indicator that something is broken or you have a malfunctioning part. This is just one of the many problems that may be posed with your HVAC unit.

Most HVAC systems kick into a higher gear when temperatures soar high above the standard setting. This puts an extra strain on the system, which may at times put it at risk. If the system has been producing strange noises lately, you then should have an HVAC repair expert run diagnostics.  Some of the strange noises you should take note of include:

1. Clanking and Banging

Banging and clanking sounds inside the AC system can be an indicator of a loose or broken part. Such shouldn’t be left unattended. The clanking sounds could be as a result of a faulty compressor. Turn off the system and contact a professional HVAC technician for diagnosis and repair. Leaving the system running despite the sounds could damage other parts of the air conditioner.

2. Clicking

Almost all HVAC systems click when the system comes on or goes off automatically. This happens as the system works to maintain the set temperature. Nonetheless, constant clicking sounds indicate something is wrong and needs to be checked. The system may click consistently if there’s an electrical issue, or if the thermostat is failing. Have an expert look into this to determine and address the issue.

3. Hissing

A malfunctioning valve or air leak may produce a hissing sound whenever the system kicks in. While you could seal the leak, a certified electrician may diagnose the main problem, hence prevent a bigger problem in days to come.

4. Grinding

Grinding noises from the system can be startling. While an expert may need to confirm the problem, these noises often surface when the fan motors start to fail. These motors are responsible for pushing air through the duct work, hence vital for the system’s cooling efficiency. The motors may have to be cleaned/serviced professionally, or replaced altogether to restore the AC’s performance.

5. Bubbling

Screaming or bubbling sounds from your AC system should be taken very seriously. These sounds indicate a possible refrigerant leak and the coolant is poisonous hence can affect your health. A leaking refrigerant could damage the entire unit too, which is why you need to have it checked immediately. Turn off the system as a precautionary measure, then have a professional identify the leaking part, seal it, then refill the compressor.

Detecting these sounds early and having any current issues handled should help your AC system last much longer.
