A heat pump creates a low-level hum as it operates and provides indoor comfort. However, if the humming is loud enough that you also start hearing some buzzing from inside the unit, it could mean that there’s something wrong with the system. These sounds can be disruptive, which is why it pays to have them assessed by a heating repair technician as soon as possible.
It is not typical for your heat pump to emit an abnormally loud humming sound. This is typically the result of one of the electrical components in your heat pump being worn out or failing to make an electrical connection when it should. A fan motor that has become seized will also produce a loud humming sound.
Solution: If you suspect that one of the electrical components is making a loud humming sound, it’s a sign that it needs to be replaced. Unless you have in-depth experience in doing electrical work, it would be best to have a highly-trained HVAC technician tinker the inside of your heat pump to determine the cause of the humming sound.
A buzzing sound coming from your heat pump system can be caused by internal parts like contactors or coils. Also, gurgling sounds are frequently the result of a low refrigerant charge. Even shrieking noises can be produced by heat pumps with contaminated motor bearings.
Solution: This typically implies that a motor is about to fail and that a replacement is due. Get in touch with professional heating service specialists for a thorough assessment of your heating equipment. This way, they can determine the cause of the problem and offer the most appropriate repair.
