Johnston Furnace Service Corporation

Johnston Furnace Service Corporation serves Marinette and the surrounding Wisconsin communities as a dedicated HVAC contractor with 16 verified reviews earning a 4.8-star average rating. The company operates Monday through Friday from 7:30 AM to 4 PM, providing heating and cooling services to residential and light commercial customers throughout the region. Technicians at Johnston Furnace Service handle furnace installations, repairs, and routine maintenance, with the flexibility to accommodate emergency service requests when heating systems fail unexpectedly.

One distinguishing aspect of Johnston Furnace Service is their work with Bryant heating equipment, including dual-stage furnaces and heat pump systems that integrate with existing ductwork. A reviewer noted that their Bryant furnace installation qualified for a federal tax credit, and the system reportedly reduced monthly energy costs significantly. The company coordinates with local service providers for related work, with one reviewer mentioning Veith duct cleaning as a recommended partner for comprehensive installations.

Customer reviews highlight specific technicians who responded to emergency calls. Chris arrived at one homeowner's residence within an hour on a weekend to repair a failed furnace, explaining the mechanical issue to a customer unfamiliar with HVAC systems. Nick handled another Friday afternoon emergency in freezing conditions, locating a needed component in their own shop to complete the repair the same evening rather than making the customer wait until Monday. These accounts demonstrate the company's willingness to go beyond standard business hours for customers in heating emergencies.
