I was called to a home to replace a failed capacitor and test the cooling works. Upon arrival, I found that the capacitor had failed and was causing the air conditioner to not work properly. I replaced the capacitor and tested the cooling works to ensure that it was working correctly. I also checked the electrical wiring and connections to make sure that they were all secure. After completing the repairs, I tested the air conditioner to make sure that it was cooling the house effectively. The customer was very satisfied with the work and thanked me for my help.
