If you own a heat pump, you most likely know that you have one of the most efficient heating and cooling systems available on the market today. It may seem as though such a high-performance system will run into few problems over time, but in actuality, a heat pump can run into a number of difficulties that keep it from running as efficiently as it could. If you notice any of the following sounds from your heat pump, it may be time to call an expert for repairs.
- Hissing: A hissing sound from a heat pump may indicate leaking refrigerant somewhere in the heat pump. This may be along the connections between the inside and outside components of your heat pump, at the compressor, or from the reversing valve.
- Grinding: If your heat pump is making a grinding noise, it’s never a good sign. Grinding often indicates a problem with the motor, the component that operates both the compressor and the blower fans. It may be that there is debris caught in the motor, or you may need to have a professional replace the motor instead.
- Buzzing: A buzzing noise may indicate an electrical problem, a repair which is never a job for an amateur. For your safety, be sure to only trust professionals with any electrical components.
- Banging: A banging noise may indicate an issue with the compressor, one of the most important (and costly) parts of your unit. On the other hand, it could simply indicate a bent fan blade or that debris is caught somewhere in the system.
Any of these noises may occur in either heating or cooling mode. And even though the sound may seem like a minor annoyance to you, it can indicate a problem that will grow worse over time. As one component of your heat pump struggles, the other parts are likely to suffer as well since they’ll have to work overtime to keep up with the workload and could eventually fail.
