"They claimed they had cleaned this system 3 times over the course of 1 week (2 man team, 8 hours each time) and sent in writing along with these pictures that it was “fire safe”."
What do you think? Obviously the FM who sent these to me did not need my reply. He no longer uses this company to clean systems in his area.
Looking at the grease trough, there is still buildup plugging
it up so the grease from the filters does not flow to the catch pan.
Looking up the stack we start to see where the cleaning stops
Further up we see clear areas that were missed
And even further us into the horizontal, we see little was done.
These were actual pictures sent by the cleaner claiming it was fire safe!
Looking into the fan bowl we see some scraping .
There were no pictures of the actual back of the fan blades.
