I was called to a home to address a problem with the air conditioner. Upon arrival, I found that the air filter was dirty and needed to be replaced. I also noticed that the coils were dirty and needed to be cleaned. Additionally, there was some condensation in the drain line, so I cleared that out as well. After completing these tasks, I tested the pressures and found that they were within normal range. The customer was very pleased with the results and thanked me for my help.
