Why Changing Your Capacitor is a Good Idea
Capacitors are small, but they do play a big role and sometimes they fail. More often than not, they will eventually. Here are some reasons why they fail.
Heat Exposure: Especially living in the valley of the sun we know about being exposed to heat. Now for capacitors being exposed to the heat for long periods of time it really takes a toll on them. So, make sure you can shade your unit as much as possible, so it spends fewer hours in the sun to maximize the life of the capacitor.
Age: Usually a capacitor is designed to last somewhere between 10-20 years, but a lot of different things play a role in the lifespan of them, such as we discussed earlier, like exposure to heat, if the capacitor is undersized, or even if it was built with wrong parts, a number of things play into how long they will last, the good thing is capacitors are not that expensive.
Voltage Rating: A lot of the time homeowners tend to find they have bad capacitors and take it amongst themselves to change them. Sometimes they pick the wrong one for their unit just trying to save a few bucks. It might seem like an easy fix but in reality, it’s best to have an experienced professional take care of it. Each A/C unit calls for a specific capacitor with a specific voltage rating and when changed themselves, some homeowners don’t always get the one intended for their unit. That can cause the capacitor to short or work even harder and shorten the lifespan of the capacitor. The wrong capacitor can even cause parts to break down and that can lead to system failure.
