I picked up a used 4 year old Aquanetics 1/4 horse chiller over the weekend. Plumbed it yesterday into my 150g tank, set it, and have not noticed much of a change in temp. It ran last night for 7 hrs and all it dropped the temp was 1 degree. I can not feel any warm air blowing off of the unit, so that's telling me there is not much of a heat exchange going on. If it needs servicing how do I do it? Just take it to a small appliance repair shop? Try to recharge it myself? Thanks.
