When your ductless air conditioner works normally, it should not make unusual noises. However, it may require immediate professional attention when it makes banging, grinding or other sounds. Let’s learn about five noises that mean your ductless cooling system in Freeport, FL, needs repairs.
1. Short Cycling
Short cycling is when your ductless air conditioner turns itself on and off more frequently than normal. A malfunctioning thermostat, refrigerant leak or broken compressor can cause this problem. Yearly HVAC maintenance helps prevent these issues and lowers the risk of short cycling.
2. Buzzing
Broken fan blades can cause your ductless cooling system to make buzzing sounds. Likewise, buzzing could be a signal that your system has a bad compressor or a malfunctioning motor. These issues require immediate and professional air conditioner repairs.
3. Grinding
When you hear grinding noises coming from your ductless air conditioner, you may need to lubricate the moving parts in its motor. Lubricating moving parts regularly helps prevent them from rubbing against each other and making grinding noises. It also lowers the risk of the motor in your system overheating.
4. Rattling
Rattling noises suggest that there are parts that have come loose inside the ductless AC compartment. Factors like vibrations and shifting can cause parts like screws and bolts in your ductless AC to come loose. Regular tune-ups will ensure all parts remain tightly in place.
5. Hissing
A hissing sound could mean that your cooling system is leaking refrigerant. A refrigerant leak can cause your entire system to freeze or blow warm air. If you hear hissing coming from your ductless AC, call one of our technicians to find and repair the leak immediately.
