What is Reyds Refrigeration?

Premium HVAC, refrigeration, and cold-room maintenance services for residential and commercial clients in Boksburg and the East Rand.

What usually causes cold room temperature fluctuation?

The most common causes are: Short-cycling from an incorrect differential; Probe positioned in the air stream or against product; Defrost cycles too long or too frequent; Expansion valve hunting from poor superheat control. A proper diagnosis identifies which one applies before any part is replaced.

Can I fix cold room temperature fluctuation myself?

You can safely check the basics — power supply, filters, door seals and airflow obstructions. Anything involving refrigerant, sealed systems or electrical components requires a qualified refrigeration technician, both for safety and to avoid voiding warranties.

How soon can you attend in Boksburg?

Boksburg is our home base — emergency calls here are typically attended the same day, often within a couple of hours. Call 069 268 0988 and describe the symptom so we arrive with the right parts.

Will it need a regas?

Only if there is a genuine leak, and only after that leak has been located and repaired. Charging gas into a leaking system is a temporary fix that costs you twice.

Cold Room Temperature Fluctuation in Boksburg

Cold Room Temperature Fluctuation is one of the faults we attend most often in Boksburg. It is a symptom rather than a diagnosis — several very different failures produce the same behaviour, which is why measurement matters more than guesswork.

Below are the causes we actually find on site, the process we use to separate them, and how quickly we can get to you. If stock, trading or comfort is at risk, phone 069 268 0988 rather than waiting for a form reply.

How we isolate the fault

Log room temperature over a full cycle rather than reading a single number
Assess heat load: door openings, product turnover, lighting and ambient plant-room temperature
Inspect the evaporator for ice build-up and check defrost timing and termination
Check condensing unit performance, head pressure and fan operation
Test controller settings, probes, solenoids and expansion valve superheat
Survey panel joints, door seals, closers and floor insulation for infiltration
