A/C coolant

Here is the post

I did this a year and a half ago. It works. Look for the post by me.

For little cost, you can get a license from the Gov. (Online Test) and purchase any Freon. I believe the cost was $25 in 2013

I had the same problem on my '76 Fireball. The place that said they could do it got 3 servicemen on the roof and then decided they couldn't do the job. Meanwhile they broke the roof trusses because of the extra load of 3 big guys in one little spot. That when I decided to get a new AC with a new MH under it.

If you are mechanical minded you could probably recharge your A/C unit. The Tap-A-Line will work but they have a very high failure rate in a short time. Without an EPA license, you can't buy R-22 and if the unit is pre 2010, thats the refergerant it probably takes. If you use an after market replacement, you'll loose capacity(BTU's). If you hire an a/c contractor to do it, you could spend around 1/2 of what a new unit would cost. And like Doug said, unless you find and repair the leak it will all be a waste of time because it will leak out again.

Others on this forum have bought a tap valve from Grainger or Ebay and have got the roof air operational. If you do an advanced search the subject was discussed last year or two. You could search YouTube videos for additional info. One is www.youtube.com/watch?v=GzowQ9Lgbhg

Bob, have you done this or has anyone that you know of done this successfully?

You could buy a self tapping saddle valve and a R22 Freon substitute on Ebay and try to get a roof top air to cool. One such company selling a substitute is Enviro-Safe. Otherwise, it is time to replace the AC unit.

Yes, thank you!

Roof A/C no, dash A/C yes. Does that answer your question?
