Any refrigeration supplier provided you have the proper federal certification.
short answer: Only people with and EPA certification may purchase R22 and/or R410A refrigerants.
R-12..........
R22 needs import license,R410A does not need anything special
One refrigerant that is chlorine free is cfc-22. This refrigerant has gained popularity in the past few years in many homes.
No
No, R410a runs higher pressures.
Most new equipment is built for and charged with R410a, a refrigerant with much higher pressures than the R22 used for decades, R22 units are still available, dry charged however, you must fill them with R22 onsite. This is how new R22 compatible equipments being sold still.
No, R410a runs higher pressures.
As of now, Air conditioner uses R22 refrigerant. In coming days ACs will come with refrigerants such as R410A, R407C etc.
An R22 coil will work properly with R410A only ifseveral conditions are met.First, the manufacturer of the coil must specify that it will work with both refrigerants. R410A systems operate at about 40 to 70 % higher pressure than R22 systems.Second, the new coil must be equipped with an inlet control (either a thermal expansion valve or orifice) that is intended for R410A. The new coil may not use a capillary tube metering system to control refrigerant flow into the evaporator coils.Third, the tonnage, or Btu capacity, of the coil and control device, and the EER/SEER of the coil must match those same ratings for the condensing unit.Fourth, if the new coil has been used in an R22 system, it must be thoroughly flushed clean of oil, and must be refitted with the proper control valving for R410A.
No.
No. r410a runs at a much higher pressure.
