There are a handful of furnace and system noises that Frog Air, Heating, & Electrical highly recommends you don’t ignore. Whether during scorching summers or frigid winters, most of us count on our HVAC heating and cooling systems to function flawlessly. However, this is not always the case. Unfortunately, most people ignore problems with their heating and air conditioning systems until it’s too late to fix them. This can lead to major system failure and costly repairs. So, before the equipment goes out, let’s discuss which noises to listen for.
Owing to their 2-stage heat compressors, most modern HVAC units are designed to be quiet. But as the unit gets older, it starts sounding louder than usual. If this starts happening, you may want to pay attention to the noises. In some cases, a simple tune-up may resolve these issues. But often, substantial repairs may be required if the problems have been left unattended for prolonged periods.
Let’s be clear: there is no such thing as a completely silent HVAC system. The majority of them make sounds in some way. Even the most efficient units will make a soft buzzing sound to indicate that the components are functioning correctly.
So, what noises are we talking about? Here’s a list of warning sounds that could mean your HVAC equipment needs to be repaired right away:
Rattling Noises
Rattling noises can be indicative of several different HVAC problems. If the noises originate from the outdoor unit, they are likely caused by debris, such as rocks or a twig. This can be easily alleviated by turning off the unit then removing the debris. Sometimes, there is noticeable damage to the condenser coils, compressor, or fan. If the rattling emanates from an interior component of the system, you need to contact Frog Air right away. We are certified HVAC professionals.
Clicking Noises
Sometimes you’ll hear clicking noises when you turn your HVAC unit on or off. This is perfectly normal. But if the noises are coming from inside the cabinet unit, you should be concerned, as it may signal your capacitor is nearing the end of its useful life. A capacitor that is not performing properly might affect your entire HVAC system. In this case, you should turn off your unit and contact Frog Air immediately.
Loud Whistling Noise
If you hear a loud whistling noise coming from your HVAC unit, you likely have a refrigerant leak or an excessive amount of internal pressure building up. Don’t waste time: contact Frog Air HVAC professionals as soon as possible because both of these issues are potentially dangerous.
Banging or Hammering Noise
Banging or hammering noises inside the HVAC unit could signal an issue with the compressor. Compressors can succumb to wear and tear with the components coming loose. These broken components generate a banging sound.
Sometimes a bad fan motor can also be the cause. Screeching noises from your air conditioner could indicate a problem with the fan motor. Fan motors extract heat from the refrigerant, and a faulty motor in the condenser system can also generate this sound.
Bubbling Noises
Bubbling noises in your HVAC unit could indicate an excessive amount of moisture. It is possible that a clog, crack, or hole in your drainage line is causing the bubbling sounds to come from the compressor. If you hear this, please contact us immediately because this is one of the issues requiring a professional’s expertise. We have the necessary tools, skills, and training to restore your unit.
