Located in Washington Township, Johnson Heating and Cooling LLC takes on residential, commercial and industrial work. The company describes itself as a full service mechanical contracting and engineering firm, with commercial, industrial and residential HVAC equipment among its specialties. Reviewers mention a steam boiler replacement that left the system running better than before, a water heater swap finished with a thorough cleanup, and a fast callback on a holiday weekend. One homeowner building a new house says the company helped design the HVAC system and then ordered all the parts. That design help is worth asking about if you are planning new construction or a major addition, since it goes beyond a standard repair call.

EMS Plumbing & Heating is a small local shop in Washington Township. We could not review a service list online, so call ahead to confirm which heating equipment they work on before booking. Reviewers describe workmanship they call fantastic and prices they call reasonable, and one says they plan to come back as a repeat customer. Another reviewer notes that when the shop was too busy to fit in a job, it still returned the call and suggested another serviceman. Long relationships come up as well, with a customer saying they have had good luck with the company for decades. For homeowners who prefer an established local name, it is worth a call.
