Look at the name plate on the unit and it will tell you how much. It may give it in ounces or pounds and ounces.

I have a goodman Model CKL 36-1K . It says Factory Charge oz R22 . Does that mean it uses R22 freon? The guy who sold it to me says it uses 410a and was only 2 or 3 years old. The serial # is 040637071 ....


Hello, the unit is a 3 ton and was built in 2004. 0z R22 stands for R-22 refrigerant. Not sure why he told you 410a but if the unit says R-22 than that must be used.

R-410A The New Refrigerant for Air Conditioning


R-410A possesses excellent cooling capacity and operates at 50% higher pressure. R-410A is a mixture (blend) of refrigerants that create properties nearly identical to R-22, but are free of ozone depleting chlorine molecules. R-410A was developed in response to an agreement between numerous countries (known as the Montreal Protocol). That stated that those countries would move toward discontinuing the use of hydrochloro-fluorocarbon (HCFC)-based refrigerants. R-410A, chemically known as an HFC (hydrofluorocarbon), contains no chlorine and will not damage the ozone layer.

R-410A is an azeotrope mixture of R-32 and R-125. R-410A cannot be used to retrofit existing R-22 a/c equipment due to significantly higher operating pressures and much higher cooling capacity as outlined in the chart below. R-410A when operating at normal operating pressures and temperatures has higher pressures. R-410A cannot be used as a "drop-in" replacement for R-22; the higher operating pressures will damage R-22 compressors and components. Therefore the old R-22 refrigerant systems needed to be buffed up some to handle the higher pressures. Because of this R-410A and R-22 equipment cannot be cross matched.

R-410A has unique performance specifications and characteristics for oil, moisture indication, thermal expansion valves, compressors, filter driers and refrigerant handling. R-410A air conditioners use newer synthetic lubricants that are usually more soluble with the R-410A than the old mineral oils are with the older R-22 refrigerants. R-410A systems use mineral oils for lubrication. R-410A systems can be more reliable than R-22 systems. R-410A air conditioners and heat pumps are today's "state of the art" systems, and utilize the most current technology available for efficient and reliable operation.

R-410A was developed to replace the ozone depleting R-22 refrigerant now used in most residential and some commercial air conditioning equipment. R-410A has no ozone depletion potential but does have a higher global warming potential.

R-410A has quickly become the refrigerant of choice for use in air conditioning applications because the refrigerant delivers higher efficiency and better Total Equivalent Warming Impact (TEWI) than other choices. Make sure that if you are installing a new air conditioning system, that you specify that the new system uses R-410A. Not only is a R-410A system more reliable, but remember that R-22 use will be discontinued in 2010. An R-410A system will give you the best and most effective service for the foreseeable future.

Any diagrams on installing a 410A TXV on a R-22 Evap coil?


You don't install a 410A TXV on an R-22 Evaporator coil.
If converting your system to a 410A, then you must be using a 410A condenser, and an evap coil, and drier rated for 410A.........

Do you have to charge a 3 ton 410a unit split as a liquid? on a 85 d day


Hi,
It is always best to charge 410a as a liquid to ensure that you get the proper mixing of the refrigerant...just turn the can upside down and take your time adding the liquid slowly...with the unit running.

Chargeing Unit


The old 410A fittings are different than the r-22 fittings. There are adapters available on ebay. Remember 410A runs at higher pressures than 22. Be sure to use gauges for 410A! Use the right gauges with the right hoses! High pressure.. Use the right gauges and the right hoses!

In a residential system that presently has a 3/8 -5/8'' lineset 30 ft long on a R22 system, can a 2.5 ton 410A system work on that size lineset?


Look at the manufacturer's instructions and it will tell you how much line set the factory charge is good for. Don't plan on using the same line set that was hooked to the R22 unit as R22 and R410a use different types of oil that are not compatible. Hope this helps.

I have installed a new split system. 410a i have flushed out the lines with flush. its been converted from r22 to 410a. My indoor coil is freezing any advice.


Either there is not enough air flow thru the coil or the charge is wrong. Is there a TXV on the system? If not, put one on.

The factory charge is 195 oz. seams kind of high for a residential heatpump to me. i'm used to a unit holding approx 5-6 lbs. this is a 410a system.


410a system is a higher efficiency unit that has a larger outdoor coil and inside evaporator coil.also the copper line coming from outside are larger one size in diameter. thats almost 12 lbs. sounds like you have a 5 ton system
