Devin K arrived on time. He was courteous. However, he did not a deep clean of the system as I requested. The system functioned correctly. The issue was that my tenant complained of a bad smell.
The technician said the system, which is only 5 years old, should be replaced because the system cannot be cleaned any further. He said a mini split system is meant to be a "disposable" system. I was shocked by this comment. I believe this technician was not ethical and just wanted me to spend money unnecessarily.
