Odd Air Conditioning Noises and What They Indicate

Is your air conditioner making odd noises? Reliable Heating & Cooling, your trusted partner for AC repair in Monmouth County, is here to help! Our team of experts compiled this list of common noises you might hear when your unit needs professional HVAC servicing and what they indicate.

Humming

The contactor relay switch starts the outdoor condenser unit when it receives a signal from your thermostat. If your air conditioner emits a humming sound, shut it off and call the Reliable Heating & Cooling experts. The problem is likely an electrical issue caused by a malfunctioning internal component and requires a licensed contractor for proper repairs.

Banging

An air conditioner typically lasts between 10 and 15 years with regular maintenance. Just like with any large appliance, however, everyday usage takes a toll on the internal parts. Banging noises are a warning sign that your AC needs immediate attention. If ignored, loose parts inside the compressor can cause further damage, leading to a potential breakdown or even a safety hazard. It's crucial to contact us for a thorough inspection and necessary repairs or replacements to avoid these risks.

As a local company, we understand the importance of having an efficient and reliable air conditioner to maintain your home's comfort.

Screeching

If the air conditioner is screeching, your unit's fan motor is probably defective. The fan belt is prone to wear out over time, and bearings eventually must be replaced. Please turn off the power immediately and contact our highly trained and experienced team of technicians for repairs. Without swift action, your AC risks further damage or total system failure.

Buzzing

Loose or unbalanced fan blades in your outdoor condenser unit create a buzzing sound. Your air conditioner might also have dirty condenser coils, loose parts, or obstructions, creating an alarming noise. A refrigerant leak is the most dangerous culprit behind a buzzing AC, though. When you call our friendly team of professionals, we will thoroughly examine your HVAC system to identify the right solution.

Refrigerant poisoning is hazardous to your health and the environment. It can even be life-threatening. If you suspect a leak, don't hesitate to call Reliable Heating & Cooling at 347-991-0014 immediately. We proudly service all makes and models to serve our community best.

Hissing

If your air conditioner's air filter is incompatible with your unit, you will likely hear a hissing sound. Moderate to severe air duct leaks are another common cause of your HVAC system making this noise. Lastly, hissing sounds arise from expansion valves that are not performing as they should. Ignoring these issues can lead to reduced efficiency, increased energy costs, and potential system failure.


Don't worry, though. When you need AC repair in Monmouth County, Reliable Heating & Cooling is here for you. We answer all of your questions thoroughly and transparently, keeping you informed every step of the way. Contact us to schedule your free in-home estimate today!
