Johnson Heating and Cooling LLC

Johnson Heating and Cooling LLC holds a perfect 5-star rating across 5 client reviews in Washington, Michigan. This full-service mechanical contractor serves residential, commercial, and industrial clients throughout Michigan, offering everything from routine furnace tune-ups to complex boiler replacements and building automation systems. The company operates Monday through Friday from 8 AM to 5 PM, providing scheduled maintenance and emergency repair services to homeowners and businesses alike.

What distinguishes Johnson Heating and Cooling is their in-house mechanical engineering capability, a full-time engineer on staff means complex projects receive professional oversight rather than being subcontracted. Their expertise spans heating boilers, process boilers, ductless split systems, and certified air balancing. The company also handles water chemical treatment for commercial systems, a specialized service many residential-focused contractors do not offer. Their "win-win" philosophy emphasizes transparent recommendations: they pledge never to recommend services they would not want performed on their own homes.

Reviewers consistently highlight rapid emergency response. Megan S. described receiving a callback within 5 minutes on a Sunday during Memorial Day weekend, with technician David arriving in under 30 minutes with a fully stocked service van. Susana Armstrong called at 9 PM during a freezing emergency and received same-day service, the technician reached her within 20 minutes and restored heat within 10. Jeff Y. praised their willingness to design and source parts for a new construction HVAC system, while Mark Olmsted noted the technician went above and beyond during a steam boiler replacement, achieving better system performance than expected.
