The main thing is to make sure your pump horsepower is the minimum you need to keep your pool sparkling clear. Too many pools built before 2005 have pump motors that have horse power that is way more than what is needed. Many pumps can be modified to draw less power, or a new pump may be in order. Over-sized pump motors cause huge electric bills, add pressure to filters/grids, and cause more frequent filter cleanings.
Quite often we can save our customers $500-$1000 per year on electricity. Also, as policy, we adjust time clocks seasonally to reflect the needs of your pool. Pump motors can run for much less time in the middle of winter as opposed to the heat of summer. It depends on your situation.
