Sounds You Should Never Hear from Your AC 

When summer temperatures are at their highest, you want your air conditioner to perform at its peak. Hissing, screeching, and banging noises, among others, are signs of potential issues that you should never ignore. Thankfully, you have Reliable Heating & Cooling for your AC repair needs in Perth Amboy, New Jersey. With our extensive expertise and commitment to customer care, we service all makes and models, providing you with the peace of mind you deserve.


Hissing

You might hear a hissing sound from your air conditioner for a few reasons. A moderate to severe air duct leak is one likely culprit. Another factor could be as simple as an air filter incompatible with your system. Lastly, a malfunctioning expansion valve might be causing the problem. No matter why your unit is producing a hissing sound, Reliable Heating & Cooling is here to help.


Screeching

If your AC starts emitting a screeching sound, it's crucial to turn it off immediately and seek expert help. Remember, this is not a DIY fix. Call the professionals at Reliable Heating & Cooling. This issue is most commonly caused by a malfunctioning fan motor in the outdoor condenser unit and requires repairs from a licensed contractor. We have the necessary knowledge, experience, and tools to fix the problem and prevent further damage to your air conditioner.


Damaged bearings in your fan motor or an impaired fan belt are other typical reasons you might hear screeching noises from your HVAC system. The fan removes heat from the refrigerant that circulates throughout the air conditioner. Like any large appliance, everyday wear and tear can eventually lead to parts wearing out and needing
repair or replacement.


Banging

Your air conditioner's compressor distributes refrigerant throughout the unit to remove excess heat from inside your house. Banging noises are a red flag that your HVAC system is on its last legs. Over time, parts become loose inside the compressor, creating a tell-tale banging noise as the pieces rattle around inside the unit.

Buzzing

Is your AC buzzing? Loose or unbalanced fan blades in your outdoor condenser unit might be behind the noise. Dirty condenser coils, loose components, or an obstruction might also be to blame for the unsettling sound. However, there is another more serious issue to consider. A refrigerant leak is a potentially dangerous problem that requires a licensed HVAC contractor to repair it immediately. They are hazardous to your health and the environment and should always be addressed quickly for your safety.


Humming

The contactor relay switch starts the outdoor condenser unit when it receives a signal from your thermostat. A defective component could be responsible for the sounds you hear your air conditioner creating. You can avoid expensive repairs by having humming sounds checked out by the trained professionals at Reliable Heating & Cooling as soon as you notice them. The reason behind the humming is potentially an electrical issue that our experienced technicians are skilled at handling safely and efficiently.
