    What makes you think you need R-22 added?

  • Dennis Boxerman May 11, 2010

    Let me suggest something here. You probably will not get any help due to the EPA laws. No one will put their name on the line for this. They could loose everything. Your problem is doable, but you may want to repost and word it differently to get someone to help ya out.



    Good Luck and much success.

Connect to the bottle and then connect to the low side (blue usually) to the low side service valve. You want the bottle to be warm. If its not warm it will be harder to charge. Don't heat the bottle just put it in the sun or put hot towels around it.

My mother had a ruud furnace/air conditioning system installed 8/2003 - the installer now says the condenser is gone. She died in 2/2010 so the system was used only 9 years. Do condensers go that quickly...


Hello
Usually there is a 1 year warranty from the installer and a 5 year from the manufacturer.
It may not be the Whole condenser is bad.But the compressor in the condenser is bad.Ask your repairman about that.R22 units are getting hard to get now as they will soon be gone.

9 yrs is a little short but it depends on how often it was used and maintained.
You certinly can try Rudd and see if they will do something.

I doubt they will. I know lennox does not.

I had a Heating and Air Conditioning Service my A/C unit in my home. I was wondering what is the going rate fro the Freon per pound?


A 30lb bottle or R22 Refrigerant your cost would be $650. As a Licensed Refrigeration Mechanic, I would charge 4 hour minimum for leak check and repair. The hourly charge is $75 and the Refrigerant which is extra to the price is $35 - 40 per pound. As the price of R22 Refrigerant goes up in price as it is being phased out per Government Regulations, you will see $75 - $100 per pound +. As for my pricing, my fellow workers say I charge too cheap. If you take $650 and divide it by 30, it would be $22/pound, but it can only be delivered to you and charged into your unit by a Licensed Refrigeration Mechanic...then the labor comes into effect for all of this. So in an nutshell, if you were charged $30 - $75 / pound , I think you did well.
I hope this clears it up.

Need special fittings to hook up gages. Repair mans standard gages won't fit on compressor unit. Where can I get fittings to adapt to your machine?


It may be a 410a unit. regular R22, R134 gauges will not work. You will need 410a gauges as it has much higher pressure in the system.
