Boost Your Business

Considering the statistics, servicing heating and air conditioning systems is an offering not to be taken lightly. CVW explains why having this facility can attract customers and boost business.

“Around 90% of your customers have air conditioning fitted to their cars, therefore you already have an existing customer base for your air con business,” explains GEMCO’s Andy Craddock. “If you cannot repair their air conditioning they may go elsewhere and you could potentially lose all their business. But if you properly kit yourself out for the job then you can look after your existing customers and potentially attract new ones.”

“The modern air-conditioning machine is an environmental recycling centre,” says Andy. “It removes refrigerant from the car and separates oil. It also cleans, dries and stores the refrigerant for re-use. Most are fully automatic, taking between 5 to 10 minutes of your technician’s labour for each re-charge. If you invest approximately £3,000 to £3,500 in an air con machine, some oils, leak dyes, nitrogen leak test kit and technician training, you could expect to get payback in 12 months with only six jobs per month. This is based on a £50 re- charge fee, minus the costs for oil, dye, refrigerant and labour. The estimated gross margin is 80%.”

AC servicing tips

Leak testing

Adding ultra-violet dye to every vehicle you re-charge will help you identify leaks faster. If the vehicle in your workshop has no refrigerant in the system, identified by zero pressure on the gauges of the machine then you should pressurize the system with Oxygen Free Nitrogen (OFN) and investigate the leak with your ultra-violet lamp.

Low refrigerant

The most common fault in the automotive air conditioning field is caused by low refrigerant and a straightforward re-charge is required. All vehicles with AC fitted, lose between 10 to 15% of their refrigerant per year, so every two years the system will not work efficiently due to lack of refrigerant. Potentially 50% of your vehicles will need maintenance every year. This does not include any additional work due to component failure.

Air conditioning: the law

All technicians working with refrigerant gases must have an F gas certificate gained by attending an approved training course and passing the end of course examination (IMI or City & Guilds).

All cars and light commercial vehicles from before 2012 use refrigerant R134a. Vehicles built after 2012 use refrigerant R1234yf. After 2017, all cars and light commercial vehicles must use R1234yf. Agricultural vehicles, truck cab or any plant and equipment can continue to use R134a.

“You will need a R134a machine for all existing cars and all existing models built this year, plus a new R1234yf machine for all cars homologated after 2012,” Andy comments. “Some dual gas machines are available which can work with either system, but you should decide if two separate machines would be a better buy for you. A dual gas machine can only work with one car at a time, whereas two separate machines could offer you more flexibility by working two cars simultaneously.”
