Adding Refrigerant To Rv Air Conditioner

A drop in the level of refrigerant translates into a drop in the machine s efficiency.

Adding refrigerant to rv air conditioner.

Schedule or perform routine maintenance before adding more freon. As the refrigerant is added the temperature differential between the air within the unit and the air in the rv should be monitored and recorded numerous times. If your technician suspects a freon leak your costs will also have to go up. When enough refrigerant has been added the temperature differential between the air conditioning unit and the rv temperature should vary by about 20 degrees fahrenheit.

Refrigerant is fairly standard in automotive air conditioning systems but the rooftop units on your rv while still using the same basic design of air conditioning do not use r134a and typically use r22. While adding a second air conditioner will be great for your comfort level it s also going to add a pretty significant amount of weight to your vehicle. Your ac s air filter blower wheel evaporator coil and condenser coil need to be cleaned before you charge your unit with more refrigerant. If you have an older r12 based system you cannot simply add r134a to it although the system can be upgraded and modified to accept r134a.

The air conditioner works by passing air over an evaporator coil which is cooled by the use of a refrigerant. Coleman is also a sealed system and the only way to recharge them is to buy access valves and a rv air conditioner recharge kit. Recharging the freon in an rv air conditioner should be left to the professionals for a number of reasons. Since refrigerant is a regulated substance than can be harmful to the atmosphere the epa demands that a leak check be.

Make sure you use an outlet rated for 30amps to prevent failure but when it comes to repair it s not really a diy job. Much of this is accomplished through how you pack. But on the other hand with a large house comes a large air conditioning unit and this will cost more to refill when it inevitably runs low. That is if it doesn t spring a leak.

Adding more refrigerant to a unit with dirty parts can damage the ac. They are sealed systems and the freon inside is made to last the life time of the unit. As has been stated already most rv air conditioners are designed to not be recharged.
