A/C Recharge



This may be a dumb question, but I want to add some refrigerant. Is the blue capped inlet in the picture the correct location to add refrigerant?
Thanks, Mike

First question is have you experience in adding refrigerant? before adding refrigerant you should always find and fix the leak.

I will not provide online information to anyone that is not versed in the safe handling of refrigerants. You get hooked up to the high pressure side and you can explode the refrigerant can and cause sever personal damage.

One does need to read about safety when working with dash air. We have owned Newmar motor homes for 23 years and at this time we own a 18 London Aire which I just had to add 12 OZ. of R-134 to bring the unit back to good working condition. We have spent thousands of dollars having A/C work done on our coaches and have found that about every year we need to add some R-134 to bring the unit back to good working condition. After all these different repairs done by A/C shops all seem to end up needing to add some R-134 after a year or so.
Yes the blue cap is the low side which is the valve to add the R-134. Do get the hose to add the R-134 with a gauge on it and follow all safety procedures and might try this first. Try a you tube video for more information.
