Great service from start to finish. From my first call with Allie, to the electrical service performed by Brandon and Sam, which was unctual, skillful, and professional. Everyone I dealt with at LHR Electrical was very efficient and adept. Would definitely recommend and use again.

Common Questions About Kitchen Hood Suppression Systems
How often do commercial kitchen hoods need to be inspected in NH?
In accordance with NFPA 96 and 17A standards, commercial kitchen fire suppression systems must be inspected every six months (semi-annually). These inspections ensure that the nozzles are clear, the fusible links are replaced, and the fuel shut-off is functional.
What happens during a semi-annual kitchen hood inspection?
Our technicians check the pressure in the cylinders, inspect the detection line, replace the fusible links (the metal pieces that melt during a fire to trigger the system), and verify that the gas or electric power to the appliances will automatically shut off if the system is activated.
Does LHR service kitchen hoods for restaurants in Manchester and Concord?
Yes! We provide comprehensive kitchen hood fire suppression services across the Seacoast and Greater Manchester areas. We focus on keeping your kitchen compliant with local New Hampshire fire codes so you never have to worry about a surprise inspection.
Why do I need to replace my fusible links every 6 months?
Over time, grease and heat can degrade the integrity of the fusible links. Replacing them during your semi-annual service is a mandatory fire code requirement to ensure the system triggers precisely when it is supposed to.

Our Clients Say
Posted on Paul DuclosTrustindex verifies that the original source of the review is Google. This company was absolutely outstanding to work with throughout our entire commercial renovation project. They are professional, provide a very reasonably priced service, handle all your fire safety needs, and are always there even in emergency last minute situations. We hired LHR Fire Protection to raise our sprinkler main in our warehouse space and rework the branch lines. The project did even start yet and one of our other contractors (not affiliated with LHR) broke a sprinkler head during demo. Josh from LHR was there within the hour to cap it off and get the rest of the building back up and running even though the ink from our contract hadn't even dried yet! They met all of our deadlines, were at every inspection on time, and surpassed our expectations with their impeccable service. Because we had such a great experience with them we are continuing to use them for our fire extinguisher annual inspections and know that we are in great hands. Thank you to everyone we worked with at LHR Fire Protection you truly deserve more than 5 stars!Posted on Barry SwansonTrustindex verifies that the original source of the review is Google.
