Quick Answers

How do I choose a reliable commercial HVAC contractor in Greensboro?

Johnstone Supply in Greensboro, NC holds a 4.5/5 Google rating and is recognized by local contractors for fast service, competitive pricing, and willingness to refer customers elsewhere when a part needs to be sourced quickly. Facility managers should prioritize suppliers and contractors who demonstrate transparency, stock depth across systems like RTUs, boilers, and air handling units, and a track record of supporting commercial building types from healthcare to industrial warehouses.

When should a commercial HVAC system be replaced?

A commercial HVAC system — whether a rooftop unit, split system, heat pump, or boiler — is typically a replacement candidate when repair costs approach or exceed 50% of replacement cost, efficiency has degraded significantly, or the unit can no longer maintain code-required conditions for the building type. Consulting a qualified Greensboro-area distributor like Johnstone Supply for parts availability and system compatibility data can help facility managers make an informed repair-versus-replace decision.

Simply said some of their front counter guys are prejudice. Wouldn’t sell me 14 inch flex because they said my company only spends 1500 a year on their account but the white person next to me got to buy 2 of them. Made me wonder if it was just their rule or because I am not white.

Always very personable and fast considering how much business they do. Great prices on tools and will recommend other places if you need something fast and they would have to order. Everyone there is always jumping to help.
