Is ef-22a propane?
ef-22a is a hydrocarbon refrigerant that replaces R22
How can you remove liquid from a r22 cylinder?
To remove liquid from an R22 cylinder, you need to first ensure the cylinder is upright and not tilted. Connect a recovery machine to the cylinder and open the liquid valve. Allow the recovery machine to pull out the liquid until only vapor remains in the cylinder.
What are normal R22 operating pressures?
The pressures depend on the temperatures so it is not possible to give "normal" temperatures. The pressures change with the outdoor and indoor temperatures. You need to be EPA certified to attach gauges to the unit to check the pressures.
How much is Freon per pound and how many pounds can be pumped into a central AC unit?
Freon is a brand name coined by Dupont. Most residential ac's use R-22 currently. Cost to the consumer is going to be around $39.80/lb. Capacity is going to vary by size of unit and different condenser/coil combinations. The average, if there is one, would be around 4 lbs. Another answer $40 a pound plus $95 per hour labor. I called the best known heating and air company in town and they said $49 per lb. Another place said $44. I started calling some of the smaller guys and finally got answers around $35. My advice is make sure you call at least 4 places before hiring anyone. Another answer The cost of r-22 is going up every day, so every time you have your system recharged it will cost you more than the last time. June 3, 2009 Tulsa, OK -------- I paid $35 for a pound of R-22 today. Another answer Freon prices vary. A few factors involved in charging an a/c unit are the factory charge, linset length, and indoor coil size. It is a complex process which if completed properly will extend the life of the equipment. More important than price is the knowledge and ability to perform the function properly and finding and fixing the reason that is causing your a/c to leak. Instead of shopping for price, you should shop for personal recommendations from satisfied customers. Another answer In whittier, CA they charge anyone 15 dollars a pound for R22. (Certified tech with epa card.) Freon is R12. Do you really need Freon R12? If you need R22, which is not Freon, it's $45 a pound.
R134a or R600a refrigerant in home refrigerators. which is more environmentally friendly or hurts ozone depeltion and global warming lesser?
R600a or Isobutane is better for the environment, but it is very flammable. I don't see is ever being used in the USA. It also use up to 20% less electricity in properly designed systems compared to R12 and R134a. In other countries R600a used in small refrigerators, in small amounts of around 50 grams. R134a is being replaced in automotive use for a refrigerant called R1234yf. R134a does cause global warming and that's why the EPA wants to replace it. I don't see R134a going away anytime soon, but the new R1234yf comes at a cost. It's very expensive and when put into an 134a system the capacity will be lowered (less cooling). Right now R22 (for home A/C) is being replaced by R410a. It's better for the environment, but it's expensive. If your getting a R22 system replaced it will be a 410 system. It requires all the copper lines to be replaced. If you still have a 22 system and it needs to be worked on, then it will cost more to repair. The cost of R22 use to be $70 per 30 lbs. right now it's almost $400 per 30lbs. This cost just get passed on to the customer. It forces people to change out old systems.
Do you add liquid or vaor to the low side?
it depends on the gas you are using. for ex\mple r134a and r22 you charge vapour through the low side and some gases are liquis charge only r404a r409 r407c and others these you charge carefully and slowly as liquid through the low side.
Is R12 Compatible with R22?
No it's not. R22 is designed for use in home HVAC systems where as R12 is intended for automotive systems. Using R22 in an automobile will cause swelling of seals and hoses, possible compressor failure due to different running pressures.
Is r12 r22 compatible?
No it's not. R22 is designed for use in home HVAC systems where as R12 is intended for automotive systems. Using R22 in an automobile will cause swelling of seals and hoses, possible compressor failure due to different running pressures.
What is the correct pressure on the high side and low side on R22 at 95 degrees?
150 high 75 low
Can you use r22 manifold gauge set for r410a?
No, you should not use an R22 manifold gauge set for R410A. R410A operates at higher pressures than R22, and using an R22 gauge set could lead to inaccurate readings and potential equipment damage. It's essential to use a manifold gauge set specifically designed for R410A to ensure safety and proper functionality.
Can you use a 134a freon manifold gauge set for R22?
No. the pressure are different, r22 runs at a fairly low pressure and you shouldn't be worried about blowing your gauges, but you won't be able to determine your super-heat or sub-cooling. for a about $100cdn you can buy the right gauges.
What is the process for converting an HVAC system from R22 to R410a using a conversion kit?
To convert an HVAC system from R22 to R410a using a conversion kit, the process typically involves recovering the existing R22 refrigerant, replacing the compressor oil with a compatible oil for R410a, installing a new filter drier, flushing the system to remove any remaining R22, and then charging the system with the new R410a refrigerant. It is important to follow manufacturer guidelines and consult with a professional HVAC technician to ensure proper conversion and system performance.
Can you mix R22 and R22a together?
No, you should not mix R22 and R22a refrigerants together. Mixing different refrigerants can lead to system inefficiency, reduced cooling capacity, and potential damage to the equipment. It is important to use the correct refrigerant specified by the manufacturer for your system.
Can you buy r22 freon from walmart?
Wal-Mart do not have r22 freon, this is a false ad.
What are the correct pressures for R410a?
The pressure for an R410a air conditioner system should be 118psi LP and 412psi HP. This is the same pressure as an R22 air conditioner.
What is the ton rating for Heil air conditioner model CA5524vkd3?

Substitute for r22?
