Our homes make all kinds of noises that are normal – the sound of your refrigerator running, the washing machine filling with water, and more. Even our heating and air conditioning systems make many sounds. You hear the air conditioner turn on to cool your house, the sound of the fan blowing, and the air moving through the vents. All of these are perfectly normal sounds.
Other HVAC noises can be dangerous. They can mean parts of your system are loose or damaged. Left alone, they can damage your system and lead to costly repairs.
A rattling sound could mean a variety of things – debris in your outdoor unit or something loose inside your system internal. If the sound is coming from the outdoor unity, turn the system off and cut the power to the unit. Look to see if there is a twig or something inside. If you hear a rattling that sounds internal, turn your system off and call an HVAC technician.
When the unit turns on and off it makes a clicking sound. A loud clicking can mean that the capacitor is struggling and can cause a lot of damage to your entire system.
A hissing sound means that air is escaping from your system, whether through the ducts or the air vents. A light hissing sound could just mean you need to change your air filter or check that the filter is the correct size. If the hissing is louder, you need to call a professional to check your ducts.
A squealing sound could mean a fan belt is bad or that the motor needs lubricant. You might have a refrigerant leak or internal pressure could be building up. Call an HVAC expert right away as this can be dangerous.
The many parts in your HVAC system are very important in cooling and heating your home and you need to ensure that they are running smoothly. The best way to do so is to schedule yearly air conditioner and furnace tune ups. They will lower the risk of major repairs and ensure your system lasts longer.
