Upon arrival came out here for an AC check, tested static static was passing, but CFM counts were failing. I took a look at the rest of the unit and got some amp draws. Everything was looking perfectly fine. Take a look at the blower wheel itself. It was pretty clean. I hook up my gauges and took a look at the charge for the outside unit. The charge was within range of what it needed to be. The only thing that I was needing was an extensive coil clean. I did let the customer know and she wanted me to just called by and let him know about that. See if you wanted to get anything done.
