Johnstone Supply

Have a Johnstone account? Probably not... Having an account at one Johnstone location does not mean you have it at all locations. Technician wasted time driving there for parts only to be turned away because the Johnstone account we have isn't affiliated with these locations. Same company, different owners, different account. Terrible business model.

Great service clean store and knowledgeable staff can't say enough great things about the staff and service

Purchased equipment from Johnstone supply in South Plainfield the Johnstone in Hamilton is much closer to the job where we were working at they refused a warrantee swap out even though they acknowledge they were under warranty because they were bought at a different branch . even spoke to the manager Paul Who also acknowledged they were under warranty from the manufacture still had no interest in providing service. Stay away from this branch at all costs

Hands down the best HVAC supplyhouse in the area. In our industry everything is about relationships, they treat their customers right and are always there to help. WARNING-If you're a homeowner or "Joe" the handyman don't shop here. They won't sell to you, Thank GOD!!! One more MR. FIX IT SAVED or DISASTER AVOIDED.
