R-410A Certification is a no-cost certification offered by Mainstream to allow you to demonstrate that you have received additional training in the handling, servicing, and recovery of R-410A equipment.

No. R-410A Certification is not required by the EPA however some equipment manufacturers require certification when handling their R-410A equipment to avoid injury or accidental damage. Yes. If you have used Mainstream's Section 608 self-study course, R-410A training is included. However our FREE R-410A Certification goes into greater detail and better prepares technicains to safely work with R-410A and R-410A appliances. The statement, "Cylinders can become over-pressurized for several reasons. See similar questions...

R-410A is a hydro fluorocarbon (HFC), which is an environmentally friendly refrigerant that is considered by most to be the likely replacement for R-22. See similar questions...

Mainstream has reviewed many of the R-410A certification programs as well as the hype that goes along with much of the R-410A frenzy. R-410A is a high pressure refrigerant and therefore there are safety issues that technicians need to be aware of. R-410A is also a near azeotropic refrigerant, therefore charging and servicing these systems is different than other 400-series blended refrigerants. See similar questions...

R-410A has a higher heat transfer coefficient than R-22. This is somewhat of an advantage for the manufacturer, but not so much for the end user. With higher transfer coefficients, one might be able to use a physically smaller system to obtain the same rating. For the person who is purchasing the unit, the efficiency would still be the same 10, 11, 12, 13, or higher SEER’s. See similar questions...

Systems that use R-410A will run at a higher pressure than systems using R-22 (approximately 60% higher). The number of service technicians currently trained and equipped to service these units are, at this time, very limited. The standard gauges, tools, and recovery equipment are not compatible for use on R-410A systems. This limits the number of service personnel qualified to service R-410A systems.

Even though R-410A performs very similar to a single component refrigerant, it should be removed from the cylinder as a liquid to insure optimum and consistent performance. See similar questions...

The EPA has not formally ruled as to whether an appliance using R-410A is considered a "Very High-Pressure Appliance" or a "High-Pressure Appliance", however Mainstream has investigated the issue and has concluded that R-410A should be considered a "High-Pressure Appliance" and the evacuation of R-410A appliances should adhere to the requirements for all "High-Pressure Appliances" See similar questions...

Yes, as long as the temperature does not exceed 125°F. This is the same guidance given for R-22 and other common refrigerants. However, you must realize that on a hot sunny day, the temperature inside a closed van or truck can exceed 125°F, so if you are storing any refrigerants in your vehicle, don't let the temperature get to 125°F.

Yes. It is a blend of HFC-32 and HFC-125 (50/50 wt%) that performs very much like a single component refrigerant. See similar questions...

R-410A is the same refrigerant whether it is called Puron, Suva 410A, Genetron AZ20, Forane 410A or Klea 66. Puron is Carrier's brand name for R-410A. See similar questions...

The safety and toxicity characteristics of R-410A have been thoroughly studied by reputable companies and organizations around the world. They have concluded that R-410A can be handled safely when the proper protective equipment is used and when appropriate safety guidelines are followed. These safety practices are very similar to the practices that have been used with R-22 and other HFC and HCFC refrigerants. There is more information on this in the R-410A manual. See similar questions...

The pressure of R-410A is significantly higher than R-22. This does not mean that R-410A, or equipment containing R-410A is unsafe. It does mean that technicians must use AC equipment; cylinders and service tools have been re-engineered to handle these higher pressures. Since R-410A acts very much like a single component refrigerant, any change in composition due to a leak is minimal. The system can be topped off, without removing the entire charge.

There is an alumni rate for students that have previously taken the specific SANS training for the certification or STAR they want to challenge. For example, if you previously took SANS Security Essentials through any of the SANS training programs (conference, online training, Local Mentor program, Instructor Led Online Training) you would be eligible for the discounted fee for the GSEC Challenge. The alumni rate for full certifications is $599 USD. The alumni rate for STAR is $75 USD. See similar questions...
