HVAC systems are never completely silent, and ductless mini-split systems are no exception. You’ll normally hear an occasional click and soft hum, but there are other noises that mean trouble for your home in Frisco, TX. Continue reading to learn about three noises you should never ignore when it comes to your ductless HVAC system.
1. Rattling
A rattling sound usually comes from outside. It generally means that something in the outside unit of the system has come loose. Sometimes, something has gotten inside the system, such as dirt or debris.
Such loose items can cause considerable damage to your ductless system. It’s a good idea to have a professional technician come out to take a look.
2. Buzzing or Humming
Again, these noises typically come from the outside parts of your system. In many cases, the problem is that the system is drawing too much power because of an electrical fault.
The danger here is that the system can start to overheat or cause a fire. Therefore, you should call a professional technician to inspect and perform ductless mini-split repair services.
3. Hissing
Hissing indicates a refrigerant leak somewhere in your system. With low refrigerant, your ductless mini-split system won’t be able to transfer heat through your system properly. Also, the low pressure that results from a refrigerant leak can damage the compressor.
If you hear these sounds, then it’s time to shut off your ductless mini-split system. This will protect it from further damage.
