Red Hot Fire Extinguisher Sales & Service currently has technicians and mobile service units based in two convenient locations that allow us to provide service to our customers in eastern Montana and western North Dakota. Our mobile service units are fully equipped and give our technicians the ability to provide our services right at your place of business. These services can range from basic annual inspections up to six year maintenance or hydrostatic testing on most types of extinguishers. There is no need to worry about not getting your extinguisher back or that you might not have enough fire protection while your extinguishers are somewhere else being worked on. Contact the location nearest you for more information.
