Refrigeration Checklist
Refrigeration is really very simple. If everyone did the things on this list you would hardly ever need to call us!
(1) Clean the outdoor condensor unit coils regularly.
(2) Check all fans are working on the outdoor condensor unit. If the unit has multiple fans, some may only turn on when the weather is hotter.
(3) Clear away leaves and other debris from around the unit that can inhibit good airflow.
(4) Clean the indoor evaporator unit coils regularly.
(5) Check all fans a working on the indooor evaporator unit.
(5) Keep the door closed on your coolroom as best as possible, especially on humid days.
Excessive humidity can cause the evaporator to frost over quickly and this reduces airflow. The hard frost also builds up and can damage evaporator fans.
If your unit seems to be frosting up excessivly it needs to be looked at before it causes worse problems.
(6) Keep an eye on motor capacitors for signs of deterioration. Capacitors are attached or located in close proximity to motors (fans). Capacitors come in a few different shapes and sizes.
Deterioration could be a sign of more complicated problems. Some may leak oil and others may deform over time.
Capacitors are more likely to fail during a period of hot weather and a failed capacitor will cause a motor to stop working.
(7) Visually inspect piping and look for signs of tiny oil leaks. This is a sign the system could be losing gas. Also watch out for failing insulation around piping. This makes the system a lot less efficient and you won't notice the lack of performance until a hot day comes around.
(8) Become familiar with the noises your machine makes when it is running correctly. Any change in noise is a sign there is a problem. The quicker you call us, the cheaper it usually works out.
