Tech arrived for a Parts and Labor Warranty HTU. Upon inspection, the capacitor was within specs. The contactor was in working condition. The condenser coils were dirty and were hosed off. The system did not appear to have Surge Protection. The filter was dirty and replaced. The drain system was clear and bleach was poured. There was no pan treatment strip. There was no inline drain safety switch however there was a wet switch. The UV system was functioning. The UV bulb has been in the system since installation. The older the bulbs are, the less effective they can be. The customer decided to replace the UV bulb today. Customer was informed of recommendations today and she would like to wait on the Surge Protector until her next visit. The customer is aware that we provide Solar and does not wish to recieve additional information at this time. The system was functioning upon departure.
