EPA Section 609 Need to Know

Losing your air conditioning on a long summer road trip is not cool! In today’s air-conditioned world, most people will not wait long before cruising into a mechanic shop to beat the heat. If you are considering the auto mechanic profession, you will want to cash in on the public’s desire to keep cool on the way to work and school. However, if you plan on servicing and repairing motor vehicle air conditioning (MVAC) units, you are going to need an EPA Section 609 certification.

Featured School

Earn your career diploma and become an HVACR Technician in as little as 5 months. The Montreal Protocol is an international treaty signed in 1987 by almost every country in the world. Its goal is the elimination the use of ozone-depleting substances worldwide.

Venting refrigerants into the atmosphere had been a commonplace practice. But this treaty prompted the United States Environmental Protection Agency (EPA) to implement the Clean Air Act. The Clean Air Act prohibits venting and requires an EPA certification for any technician handling and disposing of refrigerants. Since there is a vast number of refrigerants and applications, the Act has multiple sections that provide guidelines for specific refrigerants and their applications.

These guidelines are in place to identify which refrigerants are harmful to our atmosphere. They address how the threat can be minimized. They provide specific guidelines for each refrigerant and how it should be properly handled for its specific use.

MVACs alone represent about 15% of the global use of HFCs. Section 609 of the Clean Air Act specifically regulates the handling of refrigerants used in MVAC units. What Counts as a Motor Vehicle? Passenger cars, vans, pickup trucks, and commercial vehicles are among the obvious examples of everyday motor vehicles that have MVAC units regulated under Section 609 of the Clean Air Act.

There are also multitudes of vehicles that are not commonplace, but do have MVACs that require an EPA certified technician to service or repair. These include off-road and construction vehicles such as backhoes, enclosed-cab tractors, some cranes, and various all-terrain vehicles.

Any MVAC on a motor vehicle falls under section 609 of the Clean Air Act. Do I Need an EPA Section 609 Certification? If you plan to do auto mechanical work for a company or simply making an extra buck side getting your friends back up and running, you will likely run into a faulty A/C during the hot summer months. Anyone who repairs or services a motor vehicle air conditioning (MVAC) system for any kind of compensation must be trained and certified in accordance with section 609 of the Clean Air Act.

The 609 certification allows technicians to recover the refrigerant from these units. It also ensures technicians are trained to properly handle refrigerants. However, Section 609 certification only permits the purchase of specified refrigerants used for MVACs. Remember, just because it rolls doesn’t make it an MVAC! The refrigerant commonly used in food-truck refrigeration systems and in cargo trailers does not fall under the guidelines of section 609. They require a Section 608 certification.

Section 609 specifically covers the air conditioning system used to cool passenger compartments in motor vehicles. Featured School. Earn your career diploma and become an HVACR Technician in as little as 5 months. Both section 608 and 609 of the Clean Air Act cover the handling of refrigerants under guidelines set forth by the EPA.

Section 609 specifically covers service and repair of motor vehicle air conditioning (MVAC) units and the handling of specific refrigerants associated with MVACs. Section 608 addresses handling and recycling of refrigerants used in stationary refrigeration and air conditioning systems.

While 608 is very comprehensive and actually mentions MVAC’s, a section 609 certification is still required. The specifics regarding service and repair of motor vehicle systems are not found in section 608. Despite the differences in these two certifications, there are some areas of overlap involving the requirement of certification and record keeping.

A Section 609 does not allow you to purchase refrigerants used in stationary systems but certification under Section 608 does allow you to purchase refrigerant used in MVACs in small amounts. However, it still does not certify you to service MVAC systems. “MVAC-like systems” also fall under Section 609 because, despite their classification as appliances, they cool the passenger area of a motor vehicle. These would be larger systems that are not integrated into a vehicle’s system. Tractors and some other types of heavy equipment fall into this category. On the other hand, a Section 608 EPA certification allows you to work on systems in some buses, trains, aircraft, and boats that Section 609 does not govern.This is usually because of the specific refrigerant used in these systems.

A good rule of thumb for MVAC license requirement is that if you are going to be an employee at an automotive repair shop working on passenger vehicles, a Section 609 EPA certification is going to be satisfactory for you.

If you wish to get into commercial vehicles or aspire to own your own shop, you need to start working towards acquiring a Section 608 certification after acquiring your Section 609.

If you have a Section 608 and find yourself working on MVAC-like systems, you should consider also acquiring a section 609 to better familiarize yourself with the requirements for servicing MVACs. Please refer to our Section 608 vs Section 609 Certification page for more specifics highlighting the differences between the two certifications. In order to pass the Section 609 Motor Vehicle A/C Technician Certification exam you have to take an exam. You must answer twenty-one out of twenty-five questions correctly.

Prepare EPA Certification Tests

Is My EPA Certification Good in All States? The Environmental Protection Agency (EPA) has certification requirements for those who work with refrigerants. There are four different EPA certifications available, depending on the type of system you are working with. To pass the certification test, you need to understand the core concepts of working with refrigerants, plus specific information for your certification type. Core Requirements for All EPA Certification Types.

The EPA requires passing at least two exams for its Section 608 certifications, which cover small appliances such as residential refrigerators, window air conditioning units and vending machines. These exams include a core requirement exam as well as a specialized exam for each type of 608 certification.

If you are seeking Section 609 certification, which is required to work on motor vehicle coolant systems, you only need to take one exam. Core Requirement Exam. The core requirement exam for all 608 certifications is the same, no matter which certification you are pursuing. In the core exam, you will need to know how to use safety equipment like gloves, goggles, and in extreme cases, self-containing breathing apparatus. You will need to understand how to safely dispose of refrigerants and how to safely fill and refill refrigerant tanks.

You will also need to know about ozone depletion and clean air laws and regulations. Another aspect of the core requirements is how to recover, reclaim and recycle refrigerants. Study materials for the core requirement section of the EPA certification exams are available via the EPA website or on a variety of EPA test preparation sites. EPA 608 Type 1. In addition to the core requirements mentioned in Section 2, passing the 608 type 1 exam requires an understanding of refrigerant requirements for small appliances manufactured both before and after 1993, which is when the EPA instituted new refrigerant recycling rules.

As a result, appliances manufactured before that date are not designed with the same ozone protection standards as appliances manufactured after that date. You also need to know a variety of coolant recovery techniques, including how to recover the refrigerants from a non-operational device.

Finally, this exam includes safe refrigerant disposal techniques. EPA 608 Type 2. The EPA 608 type 2 certification is designed for those who need to work with high pressure coolant systems such as supermarket refrigeration systems. Beyond the core requirements for all EPA certification tests, this exam also covers leak detection in high pressure systems, including recognizing signs of a leak and methods of testing for leaks. This exam also covers leak repair, as well as recovery methods and requirements for different appliances. As with all exams, safe disposal techniques for the coolants used in these appliances are also covered.

EPA 608 Type 3. The EPA 608 type 3 exam is for those working with low-pressure systems, primarily chillers. This exam covers leak detection and leak testing options for a low-pressure system, which differ significantly from those used on high-pressure systems. This exam also covers the recovery of refrigerant from the system prior to a major repair; safe methods of refrigerant disposal; and requirements to safely recharge the equipment with new refrigerant following a repair. EPA 609.

The EPA 609 exam is an entirely different test from any of the 608 certification exams from groupbuy seo. The 609 exam is specifically geared to automobile mechanics. You must successfully complete this exam to work with motor vehicle air conditioning systems. This test covers everything you need to know to safely drain, repair and recharge with refrigerant the air conditioning systems in cars. This certification is not acceptable for dealing with refrigerated cargo trucks, which would require one of the above certifications. The 609 certification is only for passenger cabin air conditioning systems.

Testing Protocol

The EPA 608 certification tests are closed book, multiple choice exams. These can be taken online or in person via a HVAC distributor or a certified online testing company. Each section of the EPA exam has 25 questions, of which you need to answer 18 questions correctly. There is one section for the core requirements, and one for each certification type. The EPA 609 certification exam is 50 questions, open book, and requires 42 correct answers to pass. Stuart, Alice. “How to Prepare for the EPA Certification Tests.” Work –
