A large number of repairs that we see are not due to faulty units, but due to poor maintenance of the cleaner. Proper, regular cleaning can often be the difference between a large bill for parts and labour, and a functioning machine.

Put simply, there’s next to nothing in the way of “serviceable” parts in most swimming pool heat pumps – indeed most air source heat pumps in general. The part of any heat pump that does the hard work is its refrigeration circuit, which is a sealed loop. If this goes wrong, which is thankfully rare, it needs specialist attention. It’s not something that is otherwise touched.

It is entirely normal for air source heat pumps to frost, especially in cooler weather (start and end of pool season). All air-source units have some form of defrost function for this reason.
