Air Conditioning Maintenance In Big Island, HI FAQs​

They’re both corrosive but through different mechanisms. Salt air primarily corrodes aluminum coil fins and metal components through chloride attack. Vog contains sulfur dioxide, which reacts with copper and brass components and can also attack aluminum over time. Both accelerate corrosion of outdoor unit components, but vog’s sulfur compounds can be more aggressive toward refrigerant fittings and electrical contacts than salt alone. Properties in areas that experience both vog and ocean proximity face a more demanding environment for AC equipment than either condition alone.
Twice a year is more appropriate than once a year for outdoor units in frequently vog-affected areas. Vog deposits acidic material on condenser coil surfaces that corrodes aluminum fins and reduces heat transfer efficiency. The accumulation rate is faster than standard dust and debris, so waiting a full year between service visits allows more damage to develop than is worth accepting. Rinsing the outdoor condenser coil with clean water between professional visits also slows the accumulation rate.
Vog-specific checks include inspecting the condenser coil fins for pitting or discoloration that indicates corrosion, examining all copper and brass refrigerant fittings for green or white corrosion deposits, checking electrical connections and contactors for sulfur-related tarnishing that can increase resistance, and noting whether coil coating has worn through in any areas that should be spot-treated or recoated. The findings inform whether more frequent follow-up is warranted and whether a full coil treatment should be applied at that visit.
You can reduce exposure impact by keeping the unit clean. Rinsing the condenser coil with a garden hose from the inside out every few weeks during heavy vog periods removes acidic deposits before they have time to cause corrosion. Avoid using high pressure, which can bend the delicate coil fins. Coil coating products designed for marine or corrosive environments can be applied by a technician during service to provide a protective barrier. Positioning the unit to minimize direct vog exposure, where the site allows, also helps.
Lower humidity and less biological growth in the Kona climate means the indoor air handler is less prone to mold growth on the evaporator coil than properties on the wetter Hilo side. However, Kona’s proximity to the coast and its position under the regular vog plume from Kilauea means outdoor unit corrosion can still be a significant concern. Annual maintenance is the minimum on the Kona side, with additional attention to outdoor unit corrosion depending on how frequently vog affects the specific location.
