If you are experiencing blown fuses from your AC unit. It’s often an electrical issue with the breaker or the house wiring. Likely a short circuit or some type of a fault to ground issue. It could also be that a dirty filter is the culprit. One not uncommon answer is to check the electrical box in the condensing unit.
