I went down to the cannery last Friday to talk to a purchaser that has been experiencing some trouble with the ventilation system. The purchaser uses a big ventilation method to unfasten all of the airborne contaminants. That guy has a construction company that makes high-end plus detailed furniture pieces. The ventilation method unfastens all of the fumes from paint plus varnish plus it gets rid of the sawdust plus other air contaminants. The owner called that heating plus AC service company because he felt there was more sawdust in the air than correct plus he was upset there might be an issue with the ventilation fan. I hastily put on our overalls. I knew I was going to need to crawl through the ventilation Network to particularly get a nice look at things, however luckily, the air duct plus the cannery is about 4 ft across plus 2 ft High. There is plenty of space for a qualified serviceman to transport around inside of the area, then as soon as I accessed the ventilation system, I did not need to go any further. I unfastend the panel plus shined a light inside of the air duct. I saw numerous locales where the light seemed to shine back plus that meant holes in the air duct. I told the owner of the cannery that I needed a couple of hours to particularly assess all of the damages, but things did not look good. The 40 year-old air duct method had a lot of repairs that needed to be made if the ventilation fan was going to work properly.
