Is the water flowing too fast through the chiller? I don't think it should take this long to cool the wort, but maybe I'm wrong. How long does it usually take?
As long as your water is fairly cool (should be this time of year), you should be able to bring the temp of a 5gal batch to under 80F in 15-20mins. Make sure you're slowly stirring every few minutes to help distribute the cooler wort that was in proximity to the coils...that makes a *huge* difference in efficiency.
Also, I've got a small utility basin near my clothes washer that has a garden hose thread on the faucet. To save water, I run the output of the chiller to the empty washer and use that warm water to do a load of laundry after I'm finished. If you don't have a utility basin, using the washer's supply faucet would work too, just maybe not as conveniently.
