World Class RV Refrigeration Incorporated

Below are some answers to questions that we are asked.

1) Is it difficult to install a cooling unit?

Answer:  No. Installing a cooling unit is a simple bolt on procedure. There are no special tools or equipment required. Also, we send detailed installation instructions with each unit that we ship, and we do have technicians available by phone that can walk you through most any problem you might encounter.

2) Do I have to charge the unit once I install it?

Answer:  No. A cooling unit is a sealed system. It comes to you pre-charged and ready to install.

3) What do I do with the old unit?

Answer:  We require that you ship it back. Our company depends on the ready availability of cooling unit cores. For this reason, we send a prepaid return shipping label with every unit that we ship for you to use to send your core back with. There is no refund for doing so, but we do charge you if we do not receive a core.

4) Why do we not build new units?

Answer:  There is no need to. Some of my competitors claim that their suppliers are the only ones that can build a complete unit from scratch. This is not true at all. We have the equipment and knowledge to do so, but this is absolutely not necessary. There are 2 parts of a cooling unit that go bad...the evaporator that rusts out and the boiler assembly that gets plugged up or cracked. The other parts of the cooling unit like the condensor fins, the accumulator tank, the absorber coils, etc., are all unaffected by normal operation of a refrigerator. For this reason, why replace them? This only adds money to the cost of a replacement cooling unit...money that could be better spent elsewhere.

5) What happens to the old cooling units?

Answer:  We recycle the old cooling units by remanufacturing the cooling unit cores, and reclaiming the chemicals inside them. In this manner, remanufactured cooling units are actually good for the environment by keeping the old cooling units and the chemicals inside them out of our landfills.

6) Can a unit be repaired or recharged in the field?

Answer:  No. Charging a cooling unit is not like adding freon to an air conditioner. The chemicals involved in ammonia absorption refrigeration must be kept at a certain temperature and humidity in order for the concentration to be correct, and the tools involved are extremely specialized and not available to the general public.

7) Is it important to seal the cooling unit?

Answer:  Yes...Yes...Yes. By not sealing the cooling unit, the heat generated by the refrigerator will leak into the refrigerator compartment, thus making you think that your cooling unit is not working properly. Seal the perimeter of the cooling unit, and seal the flange of the refrigerator fins with putty tape. Do not use silicone!

8) Does a galvanized evaporator make a difference?

Answer:  Yes. The evaporator is the part of the cooling unit that gets cold. It is also the part of the cooling unit that is encased in foam. This foam is necessary to insulate the evaporator from the heat generated by the refrigerator, however, it does have it's drawbacks. The outside of the evaporator tubes get coated with ice while the refrigerator is running. When you turn off the refrigerator, the ice melts. Because the evaporator is encased in foam, the water from the melted ice cannot evaporate, so it sits on the surface of the tubing and causes rust to form. Galvanizing the evaporator aids in preventing rust to form, and ultimately adds years of service to the lifespan of your cooling unit.

Some of my competitors say that this is just a spray coating that we apply. This is absolutely true...to a point. This is not the type of spray coating that the average person can acquire. This is a special industrial coating that we use and apply in a power ventilated paint booth. So, you need to ask them this...if it is "just" a spray coating, why don't they do it?

9) Can I replace my rv refrigerator with a household model?

Answer:  Yes, but why would you want to?

First, household models are made to be stationery. They cannot absorb the vibrations from traveling. I have customers that stated they went through as many as 2 to 3 household models yearly.

Second, you will need to make major modifications to your cabinets in order to retrofit a household unit. RV refrigerators are built-ins, household units are not. RV refrigerators typically are installed above the floor, with a cabinet below them. Household units sit directly on the floor.

Third, you will have to add extra invertors (and wiring) to supply the electricity that they require.

Finally, an rv without an actual rv refrigerator has a lower resale value. This is true, and you can generally expect this amount to be the price of a new rv refrigerator plus the cost of installing it.

When you add up the extra costs required to retrofit a household refrigerator, it is not worth it.
