Common Questions
Kitchen Hood Suppression — questions we get asked.
How often does a kitchen hood suppression system need servicing?
Every six months per code, including fusible link replacement. Hood and duct cleaning runs on its own schedule based on how heavily the line is used.
Do the fusible links really need changing every six months?
Yes. They sit in grease-laden air and their response is what triggers the system — a link coated in grease may not release at the temperature it is rated for.
Does the system tie into the fire alarm?
Usually, along with gas valve shutoff and the exhaust fan. All of those interfaces get tested during service.
Do I need extinguishers as well as the hood system?
Yes — a K-class extinguisher belongs on the cooking line in addition to the hood system, and it is one of the more common things we find missing or out of date.
We work on what's already in your riser room
No rip-and-replace pitch on the first visit. We hold current manuals and parts references for every line above — when a system genuinely can't be maintained any longer, we'll show you why before we quote a replacement.
