Ano pala ang mga main reason bat nasisira ang pcb boards and other parts ng aircon?
Is it marketing strategy na rin ba na mas matipid nga siya sa kuryente peeo ang lifespan is mas shorter?
Yes its marketing strategy na din. Given the proprietary designs of inverters, we're obliged then to buy the much more expensive electronics / pcb module solely from manufacturers or just replace with a new AC. Afterall, dito talaga kumikita ang aircon manufacturers: new units and/or costly parts. Hindi tulad ng mga sinaunang aircon that we're able to get majority of its jurassic parts practically anywhere. Kaya you have to think as an investor when you buy inverters given its shorter lifespan, ROI really comes from the electricity savings.
