You can’t look ahead and plan for an unexpected AC repair … or can you? It’s never convenient for your air conditioner to stop working. The good news is that your AC will offer signs that something is wrong before completely breaking down, and many of those signs come in the form of unusual sounds.
If your AC is making noises that concern you, it may be time for air conditioning repair in Weatherford, TX, and our team is here to help. We’re outlining some unusual sounds so you know when to give us a call for repair services ahead of a complete AC breakdown.
Hissing
You may hear air moving throughout the system as it comes in through the intake, moves across the evaporator coils to cool down, and enters your home through ductwork and vents. But these blowing sounds are distinctly different from a hissing sound. If you hear hissing coming from your air conditioner, there’s a good chance you have a refrigerant leak. If the leak occurs in a portion of the line where the refrigerant is gas it can make a hissing sound. But that’s not the only possibility. A dirty air filter or blocked air vents can also cause hissing. Only an AC expert can determine the exact cause of hissing and fix the problem before it leads to a breakdown.
Bubbling
If you hear bubbling sounds coming from your AC, it’s also a sign that there is a leak in your refrigerant line. In this case, the refrigerant leak occurs in a portion of the line where the refrigerant is liquid instead of gas. It’s easy to confuse bubbling with the sound of water running. Keep in mind that It’s normal to hear water running because condensation is removed and drained from your AC system as it works to cool your home. But bubbling is never a normal sound to hear.
Squealing or Screeching
These sounds can be more obvious than others because they are loud and often high-pitched. Your AC should never make these sounds under any condition if everything is OK. If you hear squealing or screeching, it’s a red flag that something major is going wrong. A motor belt may need to be replaced or a fan blade may be scraping against another component as the fan blows. Even worse, your blower motor could be malfunctioning. Either way, you want to turn off the AC until we can inspect it so that you avoid additional damage to your unit.
Rattling
Rattling is normal in some ways, but not others. Sometimes the metal parts of your ductwork inside the AC cabinet expand and contract when there are temperature changes. Rattling should not happen all the time and if you listen, you should be able to identify exactly where any rattling is coming from. Other rattling inside your AC can mean that metal ductwork is loose. It’s also possible that other parts in your AC system are loose and rattling gently when the unit is running. A technician can check the source of rattling and fix or replace anything needed.
