The bill's sponsor, Senator Nancy Skinner (D-Berkeley), said that her bill was necessary because, "Californians ...While R410a is expected to rise some as demand grows, the costs of R410a have remained relatively the same and are generally cheaper than R-22. As R-22 phases out and units that use the refrigerant become more and more scarce, its price, due to rarity, has increased to match the additional demand and scarcity of the product.First, you need to select the refrigerant (R-410A in our case). Since the problem of icing is due to the evaporation process, you need to select the dew point. Finally, enter the pressure 93.2 psia, and you will get the saturation temperature. Figure 4 illustrates the pressure and temperature for dew and bubble points.

If you see a liquid line pressure that is more than 30 degrees saturation above outdoor temperature (like a 440 PSI liquid pressure on an R410a system on a 90-degree day), do not proceed until you have further addressed the possible causes of high head, regardless of what the superheat or subcool might be reading.

357. Post Likes. Like Doug said, all new condensing units I have seen are charged for 15 feet of lineset. You have 35 feet total, 35-15=20, 20x.6=12, 12 oz to a pound should do it for ya. and with the r410A, being low 12 oz will make a real difference in cooling capacity, try to get the charge as close as possible.

Before checking the refrigerant charge in subcooling, the indoor and outdoor temps must both be above 70°F. This provides a heat load for the system to work with and is the minimum indoor and outdoor temps that you can accurately check the refrigerant charge at. Connect the gauges and purge the air from the hoses prior to starting the unit up.

Every air compressor needs lubricating oil. You can't just use any type of refrigerant oil, as you may well know. You need a specific air compressor oil type.
