How long will the equipment last? What maintenance is required?


Our systems are designed to be maintenance-free.

We recommend cleaning air unit filters monthly. This is a two minute operation.

Most of our systems come with a 3-year limited warranty, but with normal use they should continue to operate at full efficiency for many years after that.

Apart from the modest electrical use (a CAT Air Unit uses less than half the electricity of a typical hair-dryer), there are no consumables and there are no ongoing expenses.
