3 LET’S TAKE THIS OUTSIDE Jake saw this add-on to a system while doing some AC maintenance. “I think it’s genius,” he says. Graham says: Fridgies can be innovative! Hard to tell whether this is a replacement or an addition due to insufficient condensing capacity.
1 PECKING ORDER Craig found this at a major supermarket in the Southern Highlands while doing an audit on the AC plant. “Proof that fridgies always think they are more important than the AC guy!” he says. The loader had been pinched from the HVAC compressor to keep the cabinets going. Graham says: What can I say? Balance between spoiled food and possible insurance claims against a bit of human discomfort!
2 BAILED OUT Frank in Queensland sent us this example of improvisation at its best: two 9L buckets making a duct joiner. Graham says: Improvisation is fine as long as it is only temporary. I once came across a job where the installer had run out of ducting and hadn’t tried to improvise, then wondered why there was insufficient air at the outlet.
4 FILE UNDER COMEDY Josh snapped this ingenious install at a Brisbane bookshop. Graham says: Sometimes the space for possible installation positions is very limited. Doesn’t look pretty but probably works.
5 FIRE AWAY As part of a minor renovation, Karol’s company removed an exhaust canopy and found this roof timber purlin running across the exhaust riser. “Is this not a fire hazard?” Karol asks rhetorically. “Lucky the building did not catch on fire.” Graham says: Not sure about fire regulations but the exhaust fan probably needed some support
