It was exactly 12 months ago that I wrote a glowing review for this business. Last October I paid $12,400 for two new heaters at different homes, a tune-up of an existing solar system, plus a new solar system at one of the homes. At the time, I thought the company was very professional, even though they were more expensive than their competitors. For the first 9 months after installation, the systems they installed were only operational for a few weeks at a time. I purchased the solar system with the intention of saving on my energy bills, but I saw no savings, since the system was never running. My troubles began within the first couple of weeks after installation. The pool pumps at my homes were over-heating, and the heat from the pumps was causing some of the PVC piping to warp. My pool technician who looked at the set-up said that my pumps were undersized and couldn?t effectively get the water from the pumps up to the roof and through the solar system. Fun in the Sun convinced me that the pool technician was completely wrong, and that the size of my pumps was just fine. They suggested that I get all new piping that was running into the pumps, and check the pumps for leaks, which I did (at my expense). The system started overheating again, and this time Fun in the Sun came out to the home to investigate. They found a leak in one of the solar panels they had installed brand new. They fixed the solar panel under warranty, and said everything should work now. A couple of months later the same thing was happening ? the pump would overheat, the solar system would need to shut down, etc. Once again I paid for someone to re-pipe and check all of the other aspects of the system, since Fun in the Sun convinced me my pumps were fine. The system started running again, but now my spa jets would not work. I never really noticed that the spa jets weren?t working, until the solar system started working. For all of these other months when the solar system was shut off, the spa was working. Once the solar system was operational, the spa jets would stop. I was told that my pool pumps were too small to run both the spa and the solar system at the same time. Fun in the Sun denied there was any problem. Within another couple of months, both pumps at both homes burned out. Both of these pumps were about a year or two old, but the pool technician who installed them said that the warranty couldn?t be honored, because they weren?t made for the load required by the solar system. At this time Fun in the Sun offered to sell me two new pumps that they assured me would get the job done. Interestingly, the pump that they recommended was more powerful than the pumps they were replacing. If my previous pumps were fine, why were they now recommending a larger pump? The price they offered the pumps at was approximately double the price through Amazon. I explained this to them, and they suggested that I purchase the pumps on Amazon and they would install them for a fee. They gave me a quote to install the new pumps over the phone, and then I e-mailed them to confirm the installation cost so we would have a written record. A few weeks later I noticed a charge on my credit card ? for an amount that was higher than what they told me. I e-mailed two of the owners of the company, and they told me that whoever gave me the price over the phone gave me the wrong price. When I reminded them that I confirmed the price in an e-mail to them, they said ?oh yeah ? I saw your e-mail come in, but you referenced the price towards the end and I didn?t read the whole thing?. They refused to honor the price we had agreed to. It was bad enough that they charged my credit card without my authorization (they used my credit card number from a previous transaction), they charged a higher amount than we agreed to. At this point I was so upset I hung up the phone and walked away. As bad as this was, the story actually gets worse. One of the heat-pumps they installed stopped working the other week, about 3 days before the warranty was up. I called Fun in the Sun, and I was told that they don?t do any warranty repair work on the heaters they install. I reminded them that the heaters I purchased were less than a year old, and the reason I purchased the heaters from Fun in the Sun was the warranty. They were selling these Pentair heaters for about 20% more than other dealers. The person on the phone told me that ?our heaters do have a full warranty, we are just not trained on how to service the units ? we are only trained on how to install them?. She then gave me an 800 number to call in order to have a different company come out to service the heaters. The company that the manufacturer wanted to send out didn?t have any openings for two weeks, and I needed it fixed immediately since I had a paying guest staying in my Disney property, so I had to pay $210 out-of-pocket to get one of my brand-new heaters fixed. The fact that Fun in the Sun doesn't service the heaters they install was NEVER DISCLOSED during the sales process. I never would have selected them if I knew they couldn't stand behind their products. Fin in the Sun is a big company. If I was only dealing with underlings or customer service reps that might explain their lack of caring. Since I was dealing with the owners though, it was extremely disappointing. Since the new pool pumps were installed, and since I paid this other company to fix the heaters, both systems have now been operational for a couple of months. This is the first continuous operation of these systems since last October. I would suggest looking elsewhere for your heater and solar needs.
