I am an experienced home service technician who specializes in air conditioning systems. Recently, I completed a job at a residential property where the air conditioner was not cooling properly. After inspecting the unit, I discovered that the condenser coil was dirty and clogged with debris. I cleaned the coil thoroughly, replaced the air filter, and tested the system to ensure it was functioning properly. The homeowner was very satisfied with the results and expressed gratitude for my prompt and efficient service.
