If you mixed refrigerents, the system charge needs to be recovered and labeled mix gases. Then you can try a system flush, ( never used before ) but sold at the supply houses for flushing r-22 line sets before installing r-410a equipment.

Where to put freon


There no freon in your refrigerator. It illegal to use, own, sell, product it here in the USA. Refrigeration unit use other types of refrigerants for operation. Freon destroys the ozone layer; therefore, 95% of the world has banned it use, production, distribution.

If you don't have the gages and the correct refrigent and some know how. Don't mess with it. It could be VERY DANGEROUS! Let someone who knows refrigeration units work on it. This job isn't one of those DIY job. stewbison

Evaparotor coil


  • This is a tough one for a home owner, it takes a advanced tech to find it, with specialized tools. There is one thing that a home owner can try; in a central air conditioning system, oil circulates in the lines along with the freon. So when there is a leak, the oil will excape also, leaving a oil slick, showing up on the coil as a dirty stop, because dust and dirt will stick to the oil.
If the leak is small, it is harder to find, if it is completely flat - no freon - it should be easier to spot,
A HVAC service tech will use electronic sniffers, using a limited amount of freon and bringing the pressure up in the system, using nytrogen.
In really tough ones, a dye is put into the system, and ran for awhile, then a black light is used to located the leak.
I am sorry that I don't have better news, but this will keep you informed on the whole proccess.
Have a great evening.
Sincerely,
Paul G.

I have a Nordyne unit I need to locate where the freon is put in the air conditioning central air unit


The refrigerant is charged into the system on the low side or the larger line outside at the condensor. Unless you have an EPA card to buy R22 you have to have a service tech Mainly for your safety. Get a free estimate wont cost you anything and you know upfront what it will cost. Rus

Central air conditioner won't stay running


Sounds like it cycles on either head pressure or low pressure. If you have a Carrier unit it has both controls. Is your outside fan running. Is your condensor dirty. A unit that old needs to checked bby a service tech. Remember freon does just go away. If he puts gas in your unit there is leak. HINT Ask for free estimate on repair before it is fixed. That way you know the cost up front. Rus

How do i put freon in my central heat and air my central heat and air unit is a payne


This job is best done by service tech. You have to know what your doing to be able to charge a system. Plus you have to have EPA card to handle Refrigerant. You need to call service tech. Remember if you have to put gas in there isa leak. Make sure they look for one if you ahve it recharged. A unit can run forever on the same gas. Cost of chargeing an AC can very from 100 to 300 dollars. My suggestion is to ask for a free estimate. So you know up front what it will cost. Rus

Central AC unit not cooling


If you have access to your piping system you may use a soap bubbles to test the pipe connection. the leak gas will blow the bubbles if there is leaking. But if your system is out off freon gas, you can not use this method. just try it check the connection first put the bubbles around it.
