Adding Refrigerant To Rv Air Conditioner

Schedule or perform routine maintenance before adding more freon.

Adding refrigerant to rv air conditioner.

The most common refrigerant is freon a brand name owned by dupont that is universally albeit mistakenly used as a generic term. You can expect your air conditioner to weigh at least 40 pounds. 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. 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. Recharging the freon in an rv air conditioner should be left to the professionals for a number of reasons. The air conditioner works by passing air over an evaporator coil which is cooled by the use of a refrigerant. Adding more refrigerant to a unit with dirty parts can damage the ac.

Since refrigerant is a regulated substance than can be harmful to the atmosphere the epa demands that a leak check be. As has been stated already most rv air conditioners are designed to not be recharged. They are sealed systems and the freon inside is made to last the life time of the unit. 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.

If you re an experienced rv or camper user then you know how important it is to keep your vehicles balanced. 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. 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. If your technician suspects a freon leak your costs will also have to go up.

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