Never Ignore These 5 Ductless AC Noises in Wilmington, NC
When a ductless air conditioner starts making unusual noises, it’s telling you that it probably needs some kind of maintenance or repair. If you ignore them, you risk your entire mini-split breaking down. With that, let’s learn about five ductless AC noises you should never ignore in your Wilmington, NC, home.
Grinding
If your ductless AC system starts making grinding noises, the cause is typically metal parts that are rubbing against each other. Lubricating them helps prevent this noise. During your routine maintenance, one of our service techs will inspect and lubricate the moving parts in your ductless AC system.
Buzzing
Buzzing noises typically indicate a problem, like a loose panel or frozen evaporator coils. They can also occur because of electrical issues, such as loose wiring or a failing capacitor. Electrical troubles, a loose fan blade and a malfunctioning compressor require professional AC repair services.
On and Off Short Cycling
Short cycling is another common issue that can plague your home’s ductless AC system. The most common factors for this problem include dirty air filters, low refrigerant levels and frozen evaporator coils. Short cycling can also occur because of a miscalibrated thermostat.
Rattling
Rattling noises often hint at parts that have come loose inside your ductless AC system. Over time, parts like screws and panels can come loose and rattle around inside the compartment. A yearly tuneup will ensure parts that can come loose remain tightly in place, preventing rattling noises.
Hissing
A hissing sound from your home’s ductless cooling system should prompt you to call us for professional repairs. This noise often indicates that your system has a problem, like a refrigerant leak. It can also indicate a serious problem, like a faulty expansion valve or high compressor pressure.
