Malfunctioning heat pumps can make strange noises during their everyday operations. If the heat pump in your Allen, TX home is near your patio or porch, its strange noises could disturb you when you enjoy your moments. Read on to learn the common causes of heat pump noises.
1. Metallic Clanging Noises
The metallic clanging sound comes from the unit’s fan. If you hear clanging metal sounds, turn off the heat pump and check the fan for loose parts or fasteners.
If the fan still makes strange noises, turn it off and contact a professional technician immediately. Keeping on running a defective fan can tamper with its motor and lead to severe problems.
2. Grinding and Gurgling
A heat pump transfers heat using refrigerant lines. With time, the refrigerant lines wear out, causing the heat pump to produce gurgling sounds. Contact a professional HVAC contractor immediately if you notice the noise to check it and avoid further complications with your unit.
A professional contractor will help keep your heat pump running effectively throughout the winter season. You can also get a free estimate on new furnace installation.
3. Buzzing
Reversing the valve of your heat pump could make a humming or buzzing noise during winter. When the heat is off, you may hear the sound as the valve’s solenoid coil often runs at minimal power. The noise could indicate a loose screw or other severe problems like ice on the unit, a failing compressor, or a malfunctioning motor.
4. Rattling
A lot of vibration or rattling noise could mean come of your heat pump’s components are loose. The refrigerant piping could be in the wrong position, or the screw on the heat pump’s outdoor cover needs tightening.
You can also place rubber pads under the heat pump to grip the vibration and moderate the noise. Ensure you listen for strange noises coming from the outdoor unit or air registers of your home.
Hearing strange noises when you shut your unit on or off is normal, but you need professional help if the noise persists. Contact us at All Service Heating & Air and have our team install a quieter one and HVAC maintenance.
