Air Conditioners:

 

1. It's not the Freon. When an air conditioner is not cooling as well you might like, it is not because it is low on refrigerant. A unit is either empty or full when it comes to refrigerant and - the degree to which a system is charged does not affect any other component. For example, freon does not make a unit blow breakers or fail to shut off. Units do not have services port so you can not simply hook a can of refrigerant anywhere on the unit and any time someone offers to add refrigerant to a system for $50.00, you are dealing with a jack-leg claiming to be a technician. Run!!

 

2. It is almost never the thermostat. Folks like to replace thermostats because they are handy and simple to replace. Replacing them also almost never fixes the problem!

 

Electricity

 

1. There are no RVs that are wired with 240 volts and there are no 240-volt appliances in an RV.  On a 50-amp service there are two 120-volt legs, but they feed two separate 50-amp breakers in the RV. Everything in an RV except the air conditioner will run off an extention cord with an adapter to the plug on the RV.  Do not ever wire a 240-volt receptacle and plug your RV into it. You potentially will destroy some of the components in your RV, if you do!

 

2. If you attempt to run the air conditioner off a standard extention cord, it will usually run, but you will melt the plug.
