A homeowner in Emory, TX called us because their air conditioner wasn't cooling and kept running constantly. Our technician arrived and quickly diagnosed the problem — the compressor wasn't starting due to a failed dual run capacitor. This is a common issue that prevents the compressor and fan motor from getting the electrical boost they need to start up properly. We replaced the dual run capacitor, and the unit started right up without any issues. The system returned to normal operation and began cooling the home as expected. If your air conditioner is running nonstop but not cooling, a bad capacitor could be the culprit. It's a straightforward repair when caught early, and it can prevent more serious damage down the road.
