Trying To Revive The Air Conditioner

At the end of last summer our main air conditioner decided to quit working.  Luckily we have a second air conditioner that we relied on but we had to do a few things to the RV to block the sun from coming in.  We face the southeast which means we have sun in the RV from morning through evening.  When both air conditioners work no problem but when down to one it makes it tough.  Tim researched all winter and tried to recharge our main air conditioning unit by replacing the piercing valve and recharging the unit with Freon  and it worked!  But only for a few days.  It was a valent effort and worth a try.  Check the pictures out.  Unfortunately, it did not work so a new air conditioning unit is being purchased and Tim will replace it.
