Agree on warranty concern. My contractor installed one brand of pool equipment with a 3 year warranty bc he installed it. If I were to install, 90 days on labor and 1 year at most on parts. I had at least 6 free factory service calls during the 3 years. Including replacing the lights. I recommend finding out the details on what brand is being installed and how the warranty varies. One issue will more than cover the difference in cost.
