Examples of Ventilation work you might want doing

Ventilation Tips

Filters

Clogged filters can massively increase the power usage of your system. Regular filter changes will also ensure long trouble free service from your equipment

Air handling units

These often have a 'frost lockout' (it will show up on the main panel) - if this trips it tends to mean you have clogged filters

Noise

Noise is usualy due to loose supports.... Have you tried tightening them?

Legal

Duct cleaning is now a legal requirement in commercial kitchens as is keeping records of it being done.........
