A Bayswater refrigeration tech you deal with directly
Bayswater is about 6 km from the Perth CBD, and it is one of the suburbs Sam Celesti passes through most days. When a Bayswater business calls about a cool room, Sam is the person on the line and the person who turns up with the tools. He has spent more than 20 years on commercial refrigeration, holds ARCtick licence AU55592 and works alone, so the advice you get on the phone matches the work done on site.
Every job starts with a free phone assessment of the symptoms. Once Sam has inspected the system, you get a fixed quote and nothing is done until you agree to it. Emergency jobs with stock at risk are handled first, 7 days a week.
Old cool rooms, old refrigerants
Bayswater is an established suburb, and a lot of its refrigeration is as established as its buildings. Cool rooms in older industrial units and shopfronts were often installed 15 or 20 years ago, and some still run on R22. R22 is an ozone-depleting refrigerant that Australia is phasing out under the Montreal Protocol, so supply for servicing old systems is limited. When an R22 system leaks, a simple regas is rarely the cheap fix it used to be.
Ageing systems also wear in predictable ways. Compressors draw more current and run hotter. Expansion valves stick. Insulated panels lose their seal at the joints, and doors that have been slammed for two decades stop closing properly. The cool room may still reach temperature on a mild day, then fall behind every hot afternoon.
Repair or replace? Sam will not push a new system on you. If a leak can be found and fixed and the compressor is sound, he will quote the repair. If the numbers point the other way, he will show you why, and you can compare it against a new condensing unit or a full cool room build.
For leaks on any refrigerant, old or new, our leak detection and regas service covers finding the leak first, repairing it, and only then recharging the system.

First steps when the temperature climbs
- Look at the condensing unit. If it is silent, check the isolator switch and the breaker on your board. If the fan is spinning but the coil is caked in dust, that alone can be enough to stop an old system coping.
- Keep traffic in and out to a minimum. Prop nothing open, and close any strip curtain gaps.
- Start a temperature log with times. Potentially hazardous food should sit at 5°C or below. Under 2 hours above that, it can be chilled again; between 2 and 4 hours, use it now; at 4 hours or more, it goes in the bin.
Bayswater's town centre and industrial area
The Bayswater town centre around King William Street and the rebuilt train station is home to cafés, bakeries, small restaurants and takeaway shops. These businesses mostly run a single walk-in cool room backed up by display fridges, under bench units and sometimes an ice machine, and one fault can stop the kitchen.
Further out, the light industrial area around Collier Road and Tonkin Highway holds food wholesalers, small manufacturers, caterers and trade businesses. Many of them run walk-in cool rooms and freezer rooms for ingredients and finished product, often in older tin roofed units where the plant has been upgraded piecemeal over the years. Those mixed systems are where we see the most trouble: a newer controller on an old compressor, mismatched fans, or a condensing unit relocated without enough airflow around it.
Sam also looks after nearby Morley and the rest of the eastern suburbs. For a wider look at how he handles walk-in faults, see our Perth cool room repair service.
