Pressure washers for HVAC/R service — cleaning condenser and evaporator coils, casings and outdoor units on site and in the workshop. For AC, refrigeration and heat-pump installers and service techs.
A pressure washer delivers a regulated water jet that removes dust, grease, pollen and grime from heat-exchanger fins (condenser, evaporator), unit casings and heat-pump outdoor units. In HVAC/R service the priority is being gentle with thin aluminium fins — too much pressure or a pinpoint jet bends them flat, so you work with a fan nozzle from a sensible distance. The range includes 230 V mains units and cordless battery units for rooftop or car-park work with no socket, plus lances and angled nozzles to reach densely finned coil blocks.
When choosing, check working pressure (bar) and flow rate (l/h) — fin cleaning usually needs moderate, adjustable pressure rather than an industrial machine. For fieldwork, battery power, self-priming from a canister or bucket (suction-from-tank mode), and overall weight and handling matter. Look at the detergent tank (for foaming coil cleaner/degreaser), hose and lance length, fan-nozzle quality and the available accessories — brushes, angled lances and fin-protecting guards.
