J N Johnson Sales & Service traces its roots to 1895, when John N. Johnson started the Company in Minneapolis. For over 115years we have sold and serviced the best in fire extinguishing equipment.


Today, we offer the full range of modern fire extinguishers, fire extinguishing systems, suppression and detection systems, and related products. Service is provided throughout the Twin Cities and the state of Minnesota and neighboring states by 15 service trucks. These trucks are all staffed with highly trained and experienced service technicians.


In addition to our Twin Cities headquarters we operate a complete service facility in Hibbing, MN which services the Iron Range and Northern Minnesota.


Through our Total Compliance Management (TCM) with our sister company Low Voltage Contractors, Inc. we can eliminate the service headaches of dealing with multiple vendors to service your building systems. Let us simplify your building operations.
