Heat pumps make odd noises when the reversing valves shift the refrigeration flow between cooling and heating modes in winter. The normal heat pump sounds shouldn’t be too loud or concerning, but any strange noises in your Surf City, NC, home could signify trouble brewing in your system. Here are some common heat pump noises and what they’re trying to tell you.
Loud Metal Banging
A loud metal banging sound from your heat pump could indicate a foreign object like an ice chunk, an issue related to the fan or loose components that the fan blades are hitting. The best thing is to switch off your heat pump as soon as you hear this strange noise. Call for professional heating services to fix your heat pump and eliminate the loud metal banging noise.
Vibrations and Rattling Sounds
If your heat pump produces excessive vibration noises after installation, you may need a rubber mat to reduce the vibrations. Some rattling sounds may signal a serious issue with the heat pump, like air handler problems or overly tight coolant piping. You need to hire an HVAC service technician to inspect your heat pump and recommend repairs or replacement, depending on the severity of the problem.
Gurgling and Grinding
Since heat pumps use refrigerant lines for heat transfer, the refrigerant levels deplete over time and cause gurgling noises. It’s best to ask a licensed service technician to top off the refrigerant if you hear gurgling and grinding noise. Failing to do so could cause further complications with your heat pump and premature breakdown.
Heat pumps usually make a clicking sound once they turn on, but you need help if the heat pump makes clicking sounds during the full length of its cooling or heating cycle. This could indicate an issue with the capacitor.
Strange and loud heat pump noises can be stressful. Prioritize regular maintenance and contact an expert for repairs as soon as you hear any of the above noises. Call Gideon Heating & Air Conditioning for friendly, quick and affordable preventive maintenance to keep your heat pump functioning well.
