There is a solder that is rated for 410a pressures. It's called StayBrite 8. I've been using it for 20+ years on 410a systems. It does have its limits. I don't use it on compressor changeouts. But if done correctly, it works just fine. At my company the install crews use it on all changeouts. Our failure rate is less than .03%.In this HVAC Training Video, I show the R-22 and R-410A Range of Operating Pressures on Air Conditioning Systems! I show why we Measure Pressures and Tempera...We will first examine the low-pressure side of the system, otherwise known as the vapor or suction line. During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be …pressures in a R-410A system to be much higher. A normally operating R-410A system with the same condensing temperature of 120°F and a 45°F evaporator saturation temperature will have a high side pressure of 418 psi and a low side pressure of 130 psi. Air conditioners using R-410A are specially designed for these higher pressures.

However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20˚-25˚ suction saturation below outdoor ambient.The maximum recommended temperature is often around 150 to 160 degrees Fahrenheit (65.6 to 71.1°C) for the condenser coil. What is normal subcooling for 410A? Normal subcooling for R-410A systems can range from 10 to 20 degrees Fahrenheit (5.6 to 11.1°C) depending on the specific system design and conditions.Operating an air conditioner for extended periods of time in low temperatures outdoors lowers the suction pressure to a velocity where the oil will not return to the compressor and will run dry. Also, under low ambient conditions "indoors" does not provide sufficient load to change refrigerant from a liquid to a 100% vapor.American Standard Heritage 15, R410A, Req Subcooling 10, installed 6 years ago.
