My Honda Civic was not blowing cold air , so I went to different shops to find someone that could work on my version R1234yf and avoid going to the dealership. I found Martin on google search and he had a machine to check if my AC had a leakage. He was able to detect the leakage and advised me to get my condenser fixed, which I did. I was able to resolve everything in a couple of days. Overall, he knows what he’s doing and very knowledgeable about car AC , plus great service and response time throughout the experience. I’d recommend people to come to him.

Great service!!!!! You can trust Mario, he goes above and beyond to get your AC working. I had a 2014 Cadillac XTS with a compressor problem and had to switch out a couple of times and he recharged and took out the free on with always a good attitude. Highly recommended save your money from having to go to the dealer who wanted to charge three times as much. Thanks Mario!

I came to Martin after searching the entire city for someone qualified and knowledgeable about recharging my a/c in my truck. After learning that I did not have the standard 134a refrigerant, I scrambled trying to find someone and avoid the dealership. I spoke with ALL MAJOR MECHANICS and none of them had the machine that was capable. I called Martin and he explained exactly what I needed and that he was available first thing in the morning. His price was half of what the dealer would charge for labor alone. I met him at his house, he was professional and thoroughly explained what was happening. He also checked for leaks and confirmed that my a/c was running cold and sufficient. He even called a few days later to check if I was still satisfied. If you need your a/c recharged and have a newer vehicle that requires the 1234yf, then Martin is your guy no question. Hopefully I won't have to return but I'm coming to him if I do. He's also a personal trainer but I love burgers too much.!!...

The HFO R-1234yf is the refrigerant of the future. Or, at least, that is how it has been marketed. Yf was the first HFO refrigerant to see mainstream attention. A few years back there was immense pressure in the European Union to stop using the HFC R-134a for automotive air conditioning. The pressure was there due to the extremely high Global Warming Potential (GWP) that R-134a has. R-134a has a GWP of one-thousand four-hundred and thirty. It is classified as a super pollutant.The answer to the world’s problems came with the announcement of the new HFO refrigerant known as R-1234yf. Yf refrigerant has a Global Warming Potential of only four. That is a huge difference when comparing it to other refrigerants on the market today. The only downside for yf is that it is rated as slightly flammable or 2L from ASHRAE and other air conditioning organizations.The European Union quickly phased down and out R-134a and had their new vehicles start taking R-1234yf. While the acceptance of yf is much slower here in the United States there are numerous vehicle manufacturers who have begun using this refrigerant in their newer model vehicles. With each year that passes more and more vehicles begin taking yf.

Frequently Asked Questions
  • What applications will use 1234yf?
    • Mostly it will be automobiles that use 1234yf. Eventually we will see medium duty and even heavy duty vehicles come over to the YF side as well.
  • When will 1234yf come to the United States?
    • It’s already here! While the actual phase out R-134a doesn’t go into effect until the year 2020 many auto manufacturers have already taken the initiative and have begun using 1234yf on their newer model vehicles.
  • Why are we switching refrigerant again for automobiles?
    • I am sure most of you remember the days of R-12 refrigerant. R-12 was phased out back in 1992 due to the Ozone depleting Chlorine that it contained. The substitute that we used for R-12 was the new HFC called R-134a. It was later found that R-134a had a very high Global Warming Potential, or GWP, number. GWP is a measurement of Greenhouse Gases and their effect on Global Warming. A lower GWP alternative to R-134a had to be found and thus we have the new 1234yf.
  • How is 1234yf different from R-134a?
    • 134a is a Hydroflurocarbon refrigerant while 1234yf is a Hydrofluroolefin refrigerant. While these are two separate classes of refrigerants they are in fact very close to each other. The only main difference is that the HFO refrigerants have a double carbon bond whereas HFCs do not.
  • I read that 1234yf is flammable, should I be worried?
    • Truth be told, it’s not that big of a concern. Yes, it’s mildly flammable but so is the gasoline in your car. There have been countless tests from all different companies and organizations from all over the world. Throughout all of these tests there has been only one that found bad results from flammability. I will get further into this one bad test in the ‘history’ section in this post.
  • Do I need to do anything different to work on a YF unit if I am already 609 certified?
    • No, if you are 609 certified through the EPA already you are legally able to work on these new YF units. However, it may make sense to go through 609 training again and to take the test again as these tests have been updated to include newer YF questions.
  • Do I need to be certified to purchase 1234yf refrigerant?
    • Yes, as of January 1st, 2018 you will need to 609 certified with the EPA in order to purchase 1234yf refrigerant. The only exception is when purchasing containers that contain less then two pounds of refrigerant. This new rules applies to R-134a cylinders as well.
  • Will I see a difference between temperatures and pressures when working on a 1234yf unit?
    • There is a slight difference as you go up in temperature but for the most part 134a and 1234yf work on very similar temperatures and pressure.
