I initially called Ramon because the timer for the spa wasn't working. The heater hadn't worked in a few months, but with summer upon, wasn't too concerned about that. After Ramon pointed out that a timer was not necessary for the spa since we had a manual switch for when we wanted to use it. We had been running the spa for about an hour each evening per the previous owners of the house, and Ramon said that he had never heard of anyone doing that. Since he was there, I asked for a quote to get the heater fixed and also what it would cost to get one big enough to heat the pool in the winter as well if we needed a new heater. After the estimate, I called to set up the appointment. Ramon was very professional and very thorough in explaining everything to me on the new equipment. He was on time; the initial appt. had to be rescheduled due to some weather that caused delays with other appointments he had, which is understandable. I would hire him again for any spa/pool repair..very satisfied.
