ARC-licensed cool room and cold room repair across Perth & WA. Food safety emergencies prioritised. Fast response for commercial operators — call 08 7095 3550.
A cool room failure is simultaneously a food safety emergency, a stock loss risk and a compliance breach. PEMS holds ARC Authority AU59251 — our technicians are legally authorised to handle refrigerants and respond to refrigeration breakdowns across all Perth metro and WA. We carry common parts and prioritise refrigeration calls above standard bookings.
Systematic diagnosis of cooling failure — compressor faults, refrigerant loss, evaporator icing, thermostat failure, condenser restriction and controller issues. We find the root cause, not just the symptom.
Commercial compressor diagnosis, repair and replacement. Copeland, Tecumseh and Embraco compressors. Compressor replacement is the major cool room repair — we assess honestly whether repair or replacement of the whole unit is the better decision.
Electronic leak detection, repair and licensed refrigerant top-up under ARC Authority AU59251. All refrigerant types handled. Leak location documented for your records.
Cool room door seal replacement, door panel repair, door closer and hinge replacement. A failed door seal causes constant temperature loss and compressor overwork — it's often the cheapest fix with the biggest impact.
Evaporator coil cleaning, defrost heater replacement and defrost termination thermostat replacement. Evaporator icing is one of the most common cool room faults in Perth's climate.
Condenser coil cleaning, fin straightening and condenser fan motor replacement. A dirty condenser is the single most common cause of efficiency loss and premature compressor failure — regular cleaning prevents expensive breakdowns.
Digital and analogue temperature controller replacement and calibration. Accurate temperature control is essential for food safety compliance and stock preservation.
Temperature monitoring setup, calibration and compliance documentation for food safety audits and council requirements. HACCP-ready service records provided with every job.
Most likely refrigerant loss or dirty condenser. Check whether the condenser (usually on the roof or outside wall) is clean and unobstructed. If it's clean, call us — it's likely a refrigerant issue requiring a licensed technician.
Defrost heater failure or defrost cycle issue. Ice accumulation on the evaporator blocks airflow and eventually stops cooling entirely. Usually a failed defrost heater or thermostat — a cost-effective repair if caught early.
The compressor should cycle on and off. Continuous running indicates it's fighting something — refrigerant loss, a dirty condenser or a faulty thermostat. Continuous run kills compressors. Act before it fails.
If a new door seal didn't fix the temperature problem, the fault is elsewhere — usually refrigerant level or a condenser issue. Call us for a full diagnosis.
Usually a blocked drain or defrost drain issue. Not immediately a refrigeration emergency, but if left, water pooling leads to floor damage, hygiene issues and eventually evaporator problems.
Electrical fault in the compressor motor or wiring. Do not keep resetting. Isolate and call us — repeated reset can cause further damage or create a safety hazard.
Cool room breakdowns are priority dispatches. Call 08 7095 3550 and explain the situation — particularly if food stock is at risk. We will attend as quickly as logistics allow, often same day.
Call now. A unit running warm means the refrigeration cycle is compromised. Waiting allows stock to reach unsafe temperatures and risks the compressor failing entirely — a much more expensive repair than the original fault.
Yes. ARC Authority AU59251 covers R404A, R134a, R290, R448A, R449A, R507 and all common commercial refrigerants.
Yes. Skope, True, Hoshizaki, Carrier, Friginox, Irinox and custom-built cool rooms. If it's a commercial cool room in Perth or WA, we service it.
At minimum annually — condenser cleaning, gasket check, refrigerant level, temperature calibration. High-use cool rooms benefit from six-monthly checks. Preventative maintenance is significantly cheaper than emergency breakdown response.
Yes. Full Perth metro from Yanchep to Mandurah, all suburbs. Regional WA by arrangement.
