Illegal Refrigerants: Why risk it?
Published: 09 August, 2019
Honeywell is urging garages to make sure they don’t source illegal refrigerants when dealing with air con systems this summer.
“Air conditioning is by far the most popular at-cost optional extra for UK car owners and drivers, “said Lee Hermitage, Marketing Director, Honeywell Fluorine Products Europe, Middle East and Africa. “It is not only a comfort perk – it is more often considered a safety feature, too. And rightfully so, since air conditioning can prevent drowsiness and help keep drivers alert. That all is good news for UK garages, because the more air conditioning units are in cars on British roads, the more maintenance they will require.For air conditioning to work, the system has to use a refrigerant and these refrigerants are subject to some pretty tough environmental requirements policed by the Environment Agency to limit emissions from air conditioning units in cars.”
Since January 2017, all new vehicles must be equipped with a low global-warming-potential refrigerant. In most cases this is R-1234yf. However, older vehicles are still equipped with R-134a.
Lee continued: “The first step when servicing car’s air conditioning system, is therefore to understand which refrigerant it contains, since it is illegal to service R-1234yf systems with R-134a.”
It is also essential to check if the product has been legitimately placed on the market: “Counterfeiting or smuggling are not words usually used when talking about refrigeration,” said Lee. “However, they became a reality of the industry lately. In the European Union, illegal products are estimated to make up 20% of the refrigeration market and create 20 million MT of CO2 a year – equivalent to the emissions of four million cars. According to the Environmental Investigation Agency’s study, 72% of users have been offered refrigerant in non-returnable containers, a clear sign of the refrigerant being illegal.
“With illegal products, users do not know what refrigerant really is in the container. Such unknown mixtures can represent a health hazard for technicians working with these refrigerants. An illegal product can also impact the performance of the air-conditioning system, ranging from increasing the fuel consumption to damaging the air-conditioning compressor.
There are consequences: “Being found to be in possession of these illegal products may mean fines are imposed and it may result in custodial sentences. While there is a lot of risk associated with illegal refrigerants, there are steps a business can take to make sure they never use these products.”
- Blast it! How to disinfect air con systems
With cars having been using their air con in full during the warmer months, Helen Robinson, Marketing Director at Euro Car Parts, wants to remind garages that cleaning air conditioning systems remains a good opportunity into the autumn and beyond.
“We’ve all done it – you turn on the air con after not using it for a few months, only to be greeted by a terrible smell. The reason behind this, however, is quite simple. Stagnant water droplets trapped in your dormant system are blasted out, leaving behind a foul odour and some nasty bacteria. While this is a common driver complaint, not every garage is taking the opportunity to upsell and provide a thorough cleaning and disinfection service. Fortunately, you can take three essential steps using products from Normfest that have been specifically designed and formulated to help these troubled drivers.
“The first step is to ‘bomb’ the system with Viro Dry Shot Plus, a powerful anti-bacterial cleaning agent. Using the product is simple – spray it directly into the air intake nozzles that are usually located in the passenger footwell. The spray then disperses throughout the air conditioning system for a thorough, quick and hygienic clean. Viro One Shot Plus eliminates microorganisms, prevents allergic reactions and leaves a lasting pleasant smell. A single can is enough for one application.
“In the second step, Viro Air Fresh Plus is sprayed directly into the air vents and gets to work on the air conditioner’s piping. Over time, a layer of dirt collects in the ventilation ducts and becomes a perfect breeding ground for bacteria and mould. Viro Air Fresh Plus eliminates these odour-causing particles with direct application, enabled by the included tube nozzle. It provides a long-lasting disinfection and leaves a pleasant citrus fragrance. One can contains enough spray for three applications.
“For the third and final step don’t forget the evaporator. For a complete clean, it is recommended that garages also use Viro Vaporizer to disinfect the air conditioner’s evaporator. A layer of dirt can accumulate on the evaporator fins over time, which provides ideal conditions for microorganisms to reproduce. The product cleans with high-pressure flushing, acting across the evaporator’s entire surface. It quickly kills bacteria and fungi and prevents their resettlement. The product is supplied with a 60-centimetre long tube with a rotary nozzle, helping the user to reach all corners of the evaporator. Viro Vaporizer contains enough spray for one air conditioning system. This final step completes the process, providing comprehensive protection against bacteria and bad odours.”
In conclusion, Helen added: “Disinfecting a vehicle’s air conditioning is not just about removing bad smells. It is important to periodically remove the build-up of bacteria, dirt and dust within the system to avoid discomfort, allergies and health complications. This simple three-step process could be combined with a re-gas and a new cabin filter for a complete system rejuvenation. It presents a great opportunity for garages to upsell and provides a service that directly benefits customers – solving a common driver complaint.”
- Keep cool as air con heats up
As we move towards through summer, motorists are dropping the dial across the spectrum on their climate control systems.
According to Adam White, Workshop Solutions Director at Euro Car Parts, repairers can make the most of the opportunity if they are properly equipped: “The key to profitability is offering the right services and performing them efficiently, in terms of both time and cost. By those measures, air conditioning is one of the most profitable service areas a workshop can be involved in – given the right expertise and equipment. Unfortunately, air con work is sometimes overlooked by garages who fail to see the potential profits it could bring to their business. With summer here, there are lucrative opportunities for those who are prepared.
“Air con is a key growth area for UK garages. A lot of customers that visit a workshop have some form of issue with their air con system and the average job takes just five minutes. It’s easy to see why air conditioning remains one of the most profitable services that workshops can offer. If you want to make the most of the summer rush, now is the perfect time of year to invest in quality equipment.”
As many workshops will know, automotive air conditioning systems use one of two specific gas types; either R134A or 1234YF. Adam observed: “Perhaps the most important decision for a workshop is whether to use a dual gas or double single gas setup. This will likely be dictated by the size of the business or the amount of air con servicing undertaken. The primary advantage of a dual gas machine is that you only require one unit to cater for both R134A and 1234YF, meaning less occupied space and reduce costs. The alternative is two separate machines, one for each gas. Having two machines is more expensive but it allows you to service two vehicles at once and offers greater opportunity for revenue-generation.
“Workshops should ideally have the capability to cover both 1234yf and R134a systems. We aim to support the independent aftermarket in any way we can. Our latest Workshop Solutions brochure outlines the profitability of air con servicing and is well worth a read. New machines only require a hands-on time of around five minutes, with the total air-con service time taking between 45 minutes to an hour. This effectively gives you an additional pair of hands in the workshop – an hour of labour that can be used and charged elsewhere.”
Adam continued: “Autoclimate’s products cover most of the UK market and it offers a support service that can fix 72% of the issues workshops encounter over the phone, minimising downtime. For the remaining problems, the company has 18 dedicated air con repair specialists committed to performing on-site repairs within three working days. For peace-of-mind, all its air con machines are eligible for a five-year warranty package with included annual servicing.”
Adam concluded: “Whether you are considering investing in your workshop’s first air con machine or a seasoned veteran looking to upgrade, make sure that you evaluate the market to find one that best suits your requirements. The Workshop Solutions brochure is a great source of information and advice on how to maximise workshop profitability. The latest issue provides interesting insights into air-conditioning, including comparisons of popular models and useful finance examples.”
- The shoe’s on the other foot
After my recent articles on tyres and TPMS systems, this month’s topic is wheel alignment, and the massive impact excessive toe-in or toe-out could have come MOT time.
A lot of us can spot alignment issues a mile off. I would worry if after 17 years in the trade, that a technician such as myself couldn’t tell the difference between a tyre that had been toeing-in and a tyre that had been toeing-out most of its life. If you look at a front tyre on a car and only the outer edge is bald (and the tyre has plenty of pressure in) then you walk around to the other side and discover the same issue with that tyre, it would be plain enough to see that the wheel geometry isn’t correct.
Compensate
A car with tyres like this and wheel alignment so far out must handle like it has a mind of its own - like Herbie the Beetle. However, people get used to a car in this state and will compensate to a surprising extent. When we take the car for a test drive, we may come back to the customer and say things like; “there maybe an issue with the tracking” or “the car is pulling rather a lot to one side.”
The customer then looks at us in amazement as if we are saying things just get their hard-earned money from them. We then offer a FREE wheel alignment check, and show them the virtual view on the screen. By Jove, the customer can then see with their own eyes exactly why their tyres have worn the way they have.
I first mentioned toe in and toe out. This is the way the wheels ‘point’ in relation to the forward motion of the car. Look down at your feet. Now keep your heels in position, and point your toes inwards so they point towards each other. If you try walking like this you will wear off the outside of your shoes first.
Do the same again with your heels, but point your toes outwards. This is toe-out and walking with excessive toe-out will wear the inner part of your nice new shoes and that’s the last thing you want. I’m sure you’d like it if your shoes wear evenly. The majority of track cars/race cars will be running with toe-out and negative camber. This will be topic of conversation next time as wheel geometry is a large subject.
Minutes and degrees
I also mentioned minutes and degrees earlier too. A while ago I tried explaining this to another tech and he struggled to grasp the concept of the theory behind alignment/ geometry, but he knew how to set the wheel alignment up on 99% of cars.
Getting your head around the actual maths is a different story. Think of it as a clock; there are 60 seconds in one minute; there are 60 minutes in one degree; and there are 360 degrees in a full turn. Our alignment set-up only works in minutes and degrees as it is really sensitive so no need for seconds-it would be worthless. The wind could blow and move the car slightly and that’s enough to make you panic and pick up your spanners again.
Once the alignment is set-up correctly and you’re happy with the end result, your customer will in turn be very happy. Remember, in the end they are the ones paying our wages, not just your boss. It does help if you have a happy boss too of course.
- You don’t know what YOU don’t know
The well known expression of ‘every cloud has a silver lining’ may in some cases be the reverse – that what looks like a good opportunity, actually has a hidden problem. The fitment of advanced driver assistance systems (ADAS) by vehicle manufacturers to provide ‘added value’ to their vehicles is mushrooming, as well as a significant number of these systems now becoming obligatory under vehicle Type Approval legislation. These twin trends offer a welcome increase in the work that will be needed to diagnose, repair and re-calibrate these systems in the workshop. However, the word ‘mushrooming’ may also have other connotations in this context with another well known expression of ‘being kept in the dark and covered in muck’ from the perspective of the independent workshop.
There are a number of problems when the implementation of ADAS is considered, not the least of which is just exactly what is defined as an ‘ADAS’. There are scant details when you start looking and there are ‘interpretations’ of the systems that fall into this category. From the legislative perspective, the transport section of the United Nations (which is increasingly the reference for vehicle Type Approval in the EU) simply shows the following:
