How to Diagnose a Spookily Noisy HVAC System - Depending on Its Sounds

Are The HVAC Noises Starting to Scare You?

Halloween is just around the corner, which means it’s a month for spooks and thrills! But sometimes those creepy sounds you hear in the night may be a signal that there’s something wrong with your HVAC system. Before calling a paranormal expert, check out the following reasons your air conditioning and heating system is acting up this October.

Hissing Noise Keeping You Awake?

If you hear a hissing noise and you’ve ruled out the resident black cat, it may be a sign you have a refrigerant leak instead. These leaks can be harmful to your appliances, but a refrigerant leak can poison people at home as well.

If you have a large enough leak, it could lead to drastic health issues so it’s important to understand what that hissing sound means. Refrigerant leaking from your air conditioner can cause the appliance to hiss.

This happens because the leak causes ice to build up on the coils and appliance, reducing the amount of airflow through the air conditioner. Besides the hissing, your air conditioner may stop functioning as well.

If you notice ice buildup on the copper refrigerant lines running to the outside condenser, this is often a sure sign of a refrigerant leak. If you suspect a refrigerant leak with your appliance, contact a local professional who can help set things right.

What’s That Rattling?

If the rattling noise seems to be emerging from your furnace or an internal component of your HVAC system, that means it’s time to call a local HVAC technician. They should be able to assess and solve any issues your system is having.

If you’ve pinpointed the rattling to outside your home, examine your outdoor air conditioner unit. Often times rattling can signify that there’s debris stuck inside, such as leaves, or twigs.

If the debris is visible, you can probably remove it yourself. Just remember to shut off the power to the unit before you attempt to clean it. But if you can’t find the debris, or suspect further problems, contact an HVAC technician to diagnose the source of the rattling noise.

Electrical Issues Giving You The Jitters?

If you hear a buzzing sound inside your home and have ruled out creepy crawly bugs and insects, then it may be a sign that you have an electrical issue with your HVAC system. Buzzing can be an indicator that there’s a problem with a fan motor being loose.

Or it could be that your AC unit is just aging and may need to be serviced. Sometimes, though, a buzzing sound can signify electrical arcing from your outdoor air conditioning unit, usually because the electrical voltage is not at the correct amperage.

If you suspect this may be the problem, it’s important to call a technician as soon as possible. Electrical arcing can sometimes be a sign of a broken or failing electrical component, which can also be a fire hazard.

So don’t wait around, contact an HVAC technician as soon as you can in order to save your time and energy for all the spooky thrills October has to offer.
