During my inspection today, I found a few things I wanted to bring to the customers attention. First being that the indoor unit was not equipped with a surge protection device. I gave the customer the option to do so, but they did not go with it today. I then found that the drain line was a little bit dirty. I am giving the customer the option to do a drain pan strip to help with this. I am also giving the customer the option to do a dryer vent inspection. Before my inspection today the customer said that the outdoor unit was noisier than normal. When inspecting the system, I did not find anything out of the ordinary, and took a video of the system running. The customer said that she doesn’t hear the noise anymore.
