Walk into Milani Plumbing Drainage & Heating Ltd.’s facility in Burnaby and the first thing you see is a display of the latest energy-efficient furnaces, air conditioning units and hot water tanks. Further in are customer service representatives efficiently handling all manner of inquiry. At the end of the building is a vast inventory of plumbing, drainage, heating and air conditioning components, neatly categorized in ceiling-high racks. Out back you’ll find an equipment rentals department and the bright red service trucks that are always coming or going, but never still.
