BEFORE YOU BOOK

Check before you book

No register applies

No register of car mechanics exists in any UK nation, but car air conditioning is the exception for one task: recovering refrigerant. gov.uk's F gas guidance says you must hold a qualification to recover refrigerant from the air conditioning of passenger vehicles with 8 seats or fewer and goods vehicles under 3.5 tonnes.

Ask the technician which F gas qualification they hold. gov.uk →

The Motor Ombudsman accreditation

No law requires it, but a business accredited to The Motor Ombudsman's Service and Repair Code has agreed to let the Ombudsman settle disputes. For a car air conditioning technician, that means an independent decision if you cannot agree, after the business has had eight weeks to reply.

Check the name on The Motor Ombudsman's Garage Finder; the logo alone proves nothing. businesses.themotorombudsman.org →

A price agreed before the work

Agree the price for the car air conditioning technician in writing before anything is taken apart. If no price was fixed, the Consumer Rights Act 2015 only obliges you to pay a reasonable one, and Citizens Advice says a garage may keep the vehicle while a bill is disputed but may not sell it.

Get the figure in a message, and ask to be called before any extra work. citizensadvice.org.uk →

VAT

Air conditioning regas and repair is standard-rated at 20%. Car air conditioning technicians with more than £90,000 of taxable turnover must register for VAT, charge it, and itemise it on every quote and invoice.

Ask the garage for its VAT number and whether the regas price includes the 20%. gov.uk →

“Do you hold an F gas qualification for car air conditioning?”

A good answer: Yes — a qualification from one of the awarding bodies gov.uk lists.

“Which refrigerant does my car's air conditioning use?”

A good answer: R134a or R1234yf, from the label under the bonnet.

“Will you leak-test the system before a regas?”

A good answer: Yes — vacuum test or dye — so you do not pay for gas that escapes.

“How will you recover the old refrigerant?”

A good answer: With a recovery machine, never vented.

“If it needs a repair, which part has failed?”

A good answer: Compressor, condenser, valve or a pipe, with the reason.

“Will you replace the cabin filter or treat a smell?”

A good answer: Priced separately.

“What guarantee covers the air conditioning work?”

A good answer: In writing.

AFTER

When the job is done

Check the vent temperatureCold air within minutes; note it on a hot day.
Watch for loss of coolingWeeks later, warm air means a leak; go back.
Keep the invoiceRefrigerant type and amount, parts and guarantee.
Write the reviewSomething wrong? Use make-it-right first and give the garage a fair chance to sort it before you review.

STEP 1Tell the technician, in writingDescribe what is wrong with the air conditioning and what you want. Reasonable care and skill is the standard the Consumer Rights Act 2015 sets for the work.
STEP 2Let Locufy follow it upRate the car air conditioning technician under four stars and Locufy asks if you want the garage to have the chance to fix it before the review is published; we follow it through.
STEP 3Escalate itAn accredited business can be taken to The Motor Ombudsman after eight weeks without a fix. For a garage outside the scheme, the consumer helpline hears the car air conditioning technician complaint and can refer it to Trading Standards — Citizens Advice on 0808 223 1133 in England and Wales, Advice Direct Scotland on 0808 800 9060, and Consumerline on 0300 123 6262 in Northern Ireland.
STEP 4Money still in disputeA claim over a car air conditioning technician can go to the small claims track in the county court up to £10,000 in England and Wales, to simple procedure in the sheriff court up to £5,000 in Scotland, or to the small claims court up to £5,000 in Northern Ireland — no solicitor needed.

Hiring a car air conditioning technician: questions people ask

To recover refrigerant from a car or small van system, yes — gov.uk's F gas guidance requires a qualification for it. Other mechanical work needs no licence.

An invoice stating the refrigerant type and amount, any parts and the guarantee.

Only when it stops cooling well; a system that keeps losing gas has a leak.

Most people pay between £60 and £500 per job; £150 is the typical figure. The car air conditioning repair price guide shows what changes it, and a search above lists car air conditioning technicians nearby.

Newer cars use R1234yf, which costs much more than older R134a.

Go back in writing. Under the Consumer Rights Act 2015 you can require the work to be redone if it was not done with reasonable care and skill.
