Your service men always check with me first when they arrive. They are very attentive and actually listen to what I have to say. They then adjust their treatment accordingly.
This time the tech really check my year, sometimes the tech says they check but they do not. I watched the last guy that was there and he never opened anything, never went under my house like he said he did. I want just someone to do the job I pay for
Our service technician is friendly and knowledgeable. He always asks about any specific problems or areas needing treatment and applies the necessary treatments.
My soon to be retiring tech, Steve, has always been professional, pleasant, thorough. He has always taken the time to give advice and answer my questions.
If you were not doing a good job I would send a complaint and depending on how the complaint was handled would then dictate if further action is needed.
