REMOVE charge to DECREASE liquid line subcooling Note: When adding or removing refrigerant with a TXV equipped system, suction pressure may remain relatively constant. Suction pressure is a function of the evaporator load, and the TXV only controls the evaporator superheat. Low evaporator pressure ma...
Then, use a thermometer to measure the temperature of the refrigerant tank outer surface and connect a pressure gauge to the tank to measure its internal pressure. Find the saturation pressure corresponding to the measured outer surface temperature from Table 9-1. If the de...
PROBLEM TO BE SOLVED: To reduce GWP: Global Warning Potential, increase cooling / heating efficiency, reduce power consumption, and improve COP in an air conditioner using a refrigerant R410A. SOLUTION: A working fluid in which a refrigerant R410A is recovered, is composed of Difluoromethane ...
Annual inspections can reduce home appliance costs by replacing small components, like a compressor or condenser, before you are forced to replace an entire AC unit. HVAC specialists can also provide a quick Freon charge and fix any refrigerant leaks to keep your system working at optimal performa...

Charge the unit with enough R-410A to meet the manufacturer's specification if, based on the information from their data sheet, there may be a too low sub-cooling problem. If this is the case, it is most likely due to lack of refrigerant. Sub-cooling temperatures that are too high may...
Professionally installed systemsare just about the same with one exception – they typically do not contain enough refrigerant for the system to run properly. Therefore, they require additional refrigerant charge to be done by a licensed technician who is certified to handle refrigerant. It is our ...
If I decide to install it myself, will I need vacuums to charge up the lines. I assume that the lines need to be charged up with refrigerant and that it has to be setup by a qualified air conditioning technician correct? YES. YOU WILL NEED A SET OF GAUGES FOR R410A AND A VACUUM...
You can usually find a local supplier that sells to the public, but as a bonus with the EPA cert, you can get licensed by your state to work as a refrigerant contractor. I was a service tech for years and the amount of people that just dumped that stuff into the air is horrifying....
