Straightforward, precisely engineered climate work
Precision Air Worx was founded by Deric Um, a Sydney HVAC tradesman with over 10 years in the industry. After a decade working across residential homes, commercial fit-outs and refrigeration jobs across Sydney, Deric started Precision Air Worx to deliver the kind of climate work that Sydney homeowners and business owners actually want and rarely get.

We do not cut corners. Proper commissioning, correct refrigerant charge, clean job site.
