Changing out an air conditioners refrigerant isnt like changing your cars gasoline from regular to premium. No more sweep charging or fast flush.
Your existing condensing unit and cooling coil are not suited to the new higher pressure refrigerant.
Changing from r22 to r410a. As of 2012 the heating ventilating and air conditioning HVAC industry is in the process of changing over from ozone-depleting R-22 refrigerant to environmentally-friendlier R-410A refrigerant. By Robert Scaringe PE Many contractors are experiencing compressor burnout problems with R-410A HVACR systems soon after theyre converted from R-22 refrigerant. A conversion should always include condenser evaporator and line-set change-outs but the problem lies in the fact that linesets cant always be changed out.
This is a video focusing on the process of changing a R22 condenser and evaporative coil to a 410a condenser and evaporative coil. This will help you at lea. On the AC side everything really needs to be changed R22 uses mineral oil based lubricants.
R410a uses ester oil lubricants. Getting all the residue out would cost a bunch and these cant be mixed. The compressor will need to be changed and the TXV orifice will need to be changed.
Changing from R22 to 410A. You do not need to replace the lineset when changing to R410a as long as you properly flush it with a good flush kit. Generally R410a systems call for a smaller line set than R22 systems do so I dont see how you can end up with an undersized line set unless the origional system had an undersized line set or you.
A 13 SEER R22 condenser matched with a 10 SEER R22 evap coil. Often gives a system efficiency of 8 to 9 SEER. R410A condensers are designed to operate at a higher saturated evap temp then R22 condensers.
So matching an R22 designed only evap coil with a R410A condenser will yield a low efficiency and loss of capacity. R22 refrigerant and its HFC replacement R410A are totally incompatible. Your existing condensing unit and cooling coil are not suited to the new higher pressure refrigerant.
This enclosure will have to be rebuilt or you may have to buy a new air handler that. REM2P3600A 3 TON R22 AIR HANDLER 2- An R410A compressor of equilivent BTU. The 36 in the model numbers above represent the tonage and BTU 36000 BTU is 3 ton 3- An R410A accumulator.
The one in there will not work. 4- An R410A expansion valve TXV inside and outside. The one in there will not work.
This is the refrigerant metering device. System requirements changing from R-22 to R-410A Originally Posted by rickyccong Recently I have inspected by Eddy Current Tubing Examination on York Chiller Mode. YSCBCAS35CD D on the Condenser and Evaporator Enhanced Copper tube.
Im replacing an R22 split system with a new R410A system. Because this is a 2nd story system with the evaporator coil in the attic the lineset runs down through a wall into the crawlspace. The project manager tells me that the run through the wall is too tight to remove the old lineset 12 years old and run a new one so our options are to either reuse the old one or run a new one out of.
The old R22 compressors were not so picky. A tech could do a poor job of installing the R22 condenser and the unit would last for 10 years or more. With r410a units the installers must have there process dialed in tight.
No more sweep charging or fast flush. Each system must be vacuumed down to 350 700 microns. If you have existing R-22 systems that need frequent repairs or are nearing the end of their operating life transitioning to R-410A equipment may make sense.
With the latest energy efficiency standards in full effect you may have questions about replacing existing units especially when switching from R-22 to R-410A equipment. In 1987 the Montreal Protocol signed by the United States set a timeline for the elimination of R22 systems and conversion to more environmentally sensitive systems fueled by R410A. The old split system unit was running with R22 refrigerant and the new one uses R410a.
The installer originally said the piping needed to be changed but on the day of installation flushed the pipes instead before installing the new unit Daikin FTXR50K. I am converting R22 system to 410A. R22 system uses mineral oil 410A synthetic before coil installation evapand condens do I need to clean or flash the lines and if yes how the process itselfOr is there even a need of any kind of treatment for lines presiders.
If youre completely changing out your R22 equipment for R410A equipment there is no reason that shouldnt work. Both systems use typical ductwork. Can I buy a YORK new compressor 410 and still use the coils in the home for r22.
Kyle from Ingrams. 1 R22 and R410A Compressor 1 2 R22 and both R410A Co mpressors 3 Only R22 4 Only R410A Compressor 2 EXPERIMENTAL RESULTS R22 System Tests Figure 3 shows the cooling capacity and COP as a function of the outdoor temperature.

We have a 12 yr old builder grade R22 ac furnace system in the attic of our 12 yr old home in Dallas TX. It uses electricity to run the ac and gas to heat the house. It also specifies on the label that it is suitable for r22 or r410A Condenser outside is a 5 ton R22 Amana.
Changing R22 unit to R410a. Hi all I am about to change my 35 ton 13 year old Goodman AC unit out with a new 14 or 16 SEER unit. Im getting conflicting advice from companies that I am getting quotes for and could use your advice.
Should I stick to a 35 ton unit if I currently have a 35 ton unit when I switch to R410a. R-410a doesnt share the same chemical properties as R-22. It runs at a much higher pressure.
Systems designed to handle R-22 will not be able to handle the huge amount of force and parts will burst. While its theoretically possible to overhaul an old system to. Changing out an air conditioners refrigerant isnt like changing your cars gasoline from regular to premium.
Lets take a closer look at why you cant switch out the two refrigerants so easily. Why you cant replace R-22 with R-410A R-410A works at a much higher pressure than R-22.
