Washed condenser coil. Customer stated he had just done this too a couple weeks ago. Checked electrical. Compressor is running on very high amperage. This number also goes up in higher temperatures. Customer stated that made sense since the unit doesn’t work very well in high temperatures. Checked freon pressures and they are slightly low but advised customer it wasn’t affecting cooling performance. He asked h
