Because their HVAC system was having some start-up issues, this client from Los Angeles, CA, called Pioneers Heating and Air. One morning, the compressor outside their residence suddenly stopped working. Instead, it repeatedly made loud humming noises while attempting to start but failed. As a result, the air conditioner spewed heated air when it eventually switched on. To identify the issue, our technician went to their home that day. We examined the condensing unit's guts and tested the AC capacitor using a multimeter. Finally, we determined the culprit?the system's circuitry overheated due to extremely high outdoor temperatures, causing the AC capacitor to fail. After testing the AC unit, we replaced the defective capacitor. Within the next two to three minutes, it finally turned on. We finished the replacement of the AC capacitor?so simple and quick!
