It’s entirely normal for a heat pump to occasionally make certain loud noises — for example, when starting. However, not all such noises are benign. Here are three different noises that should concern you if you hear them coming from the heat pump in your Hanover, PA home.
1. Gurgling Noises
Gurgling noises typically indicate that your heat pump is low on refrigerant. This is a serious issue that will significantly impair the pump’s functioning, whether it happens to be working in cooling or heating mode. Since it’s dangerous to handle refrigerant, always call an HVAC maintenance professional to resolve the problem.
2. Thumping Noises
If you hear a persistent and repetitive thumping noise coming from your heat pump, this likely means that a fan blade inside your unit’s compressor is hitting something. The object that the blade is striking could be a stray wire, some accumulated ice, a twig, or another piece of debris.
If you hear this noise, you should turn off your unit and call a repair technician as soon as possible. Keeping the unit running will only risk damaging the fan blade and throwing it out of alignment.
3. Vibrating Noises
Vibrating noises are fairly normal for a heat pump, so it can be difficult to discern when this particular noise is a cause for worry. If there is an underlying problem, it can be a minor issue like a loose cover panel or it could be something much more serious. If you are unsure, it’s best to play it safe and call over a repair technician to determine what, if anything, is wrong.
