Why is my heat pump making a lot of noise?
If your heat pump has suddenly become noisy, you may suspect that it’s about to have a breakdown. Noisy heat pumps are more common in the winter. However, the loud noises are often due to the valves shifting to put the unit into defrost mode. While a noisy heat pump could be simply that — noisy — it may also be cause for concern.
When to take action against heat pump noise?
If the difference between the Rating Level of the specific noise and the background noise is +5dB, it’s deemed to be of “marginal significance” and acceptable. However, a difference of +10dB or more indicates complaints are likely. Most local authorities will take action against the organisation producing the noise when it reaches this threshold.
Why does a heat pump make less noise than a dishwasher?
Noise from ground source heat pump. In contrast, ground source heat pumps sound not dissimilar to a dishwasher. They also generally make less noise because there’s no fan component and the heat source is warmer, so there’s less strain on the compressor.
What’s the legal noise level for a heat pump?
The closer the machine is to the property line or a neighbor’s window, the stricter enforcement. The standard acceptable noise level at the closest property line is less than 42 decibels (dB). If a unit is rated louder than 42dB, most jurisdictions require the granting of planning permission.

What to do if your heat pump is dirty?
Clean off your heat pump and clear away any debris that may be blocking the way. Air filter is dirty: Air filters are put in place to catch dirt and debris, but when too much builds up, it can block airflow to the compressor, the part of the unit that actually heats the air. This solution is simple, too.
What happens if a heat pump fan hits something?
Even if the contact doesn’t damage the fan or motor, the fan blades could damage whatever they’re hitting. For example, tubing could end up with a split tube that leaks refrigerant. There are all kinds of potential damages that can occur when your heat pump’s fan is hitting something else inside the unit. To prevent issues, turn it off.
