anyone know what to do with a chiller than runs all the time? i have a custom sea life chiller i've had for about 10 years and lately it runs even at night when it's not that hot. do these need to be recharged every once in a while or is it a tell-tale sign it's going bad? unfortunately the company is out of business and i'm not sure who to take it to to get it checked out. i tried refrigeration repair, but they don't know what i'm talking about. i'm not sure if its worth the hassle to call around or not...
