GEA Screw Compressor, Dewalt Fan, & Buddy Heater: An Admin Buyer's Guide to HVAC & Equipment
If you're an admin buyer like me, you're probably juggling a dozen requests at once. Operations needs a new GEA screw compressor for the plant. Someone's asking about a Dewalt fan for the shop floor. Facilities is wondering if a Mr. Heater Buddy Heater is good enough for the warehouse. And finance wants to know if a heat pump or furnace is the better investment. Sound familiar? I've been managing this kind of equipment procurement for five years now, processing roughly 60-80 orders annually across eight different vendors. So here's my honest, been-there-done-that take on the most common questions I get.
