Wouldn’t it be nice to get all cosy holidaying around the UK in your car with the AC in full blast? Or perhaps, would you like to sell your vehicle fast? If you answer yes to both questions, you should keep the unit in great condition. That includes having it replaced or repaired when needed. 

The average car AC repair cost is £440. Now, that sounds like a lot. But remember that mechanics consider several factors to reach the right price for their services. This guide examines each to give you the best estimate for car AC repair fees.

What affects car AC repair costs?

What is the average car AC repair cost? To answer this question, let’s examine the factors affecting the price. 

Car repair parts and labour

A considerable portion of what you pay a technician goes toward car repair parts and labour for the following reasons:

  1. The air conditioner is a sealed system with different interrelated parts. Usually, technicians don’t just repair a component but also perform a thorough inspection to ensure they’re fixing the root cause. 
  2. Credentialed and experienced technicians command a higher hourly labour rate. Most mechanics charge £25 to £80 an hour, depending on the location, experience, and expertise.
  3. Some parts are challenging to fix. The car AC compressor, for example, could cost you over £500 for the component alone. This is because technicians should find one that fits the space. Further, it is more likely to be defective when the problem is diagnosed.

Whether the parts are original or aftermarket also matters. OEM (original equipment manufacturer) components are always the best to use since they are guaranteed to fit. But they can also be pricey, so many mechanics opt for aftermarket ones. These cheaper alternatives don’t necessarily come from the car’s manufacturer. They might not be an exact match, but they should work just as well. 

One advantage of aftermarket parts is that technicians have wider choices. The downside is that it might take longer to find the right parts. Using them might also void your vehicle’s warranty.

Your location

Your residence or the mechanic’s address will also determine the overall car AC leak repair cost. In particular, it is a huge factor in labour and car-part availability. 

Mechanics often charge the highest in busy cities, such as London, where the average daily rate is £50. You might also spend more if the technician is working in a dealership than in their own garage or shop. If you want to spend less, look for independent car repair experts near you. 

Meanwhile, getting your vehicle's AC fixed in rural areas might be tricky. It can take time for the parts to arrive, or you'll find fewer mechanics to work on the issue.


Your auto insurance policy covers a portion of the air conditioner regas cost. But this is usually only if it’s due to an accident or comprehensive coverage. 

Comprehensive plans are the most inclusive and can pay for weather damage, theft, glass breakage, and other incidents not related to accidents. If you live in a place with severe weather conditions, this could be a lifesaver. 

Keep in mind, though, that your deductible will apply. If you have a £500 deductible and the total repair cost is £1,200, you’ll only pay £700 out of pocket. Also, some insurers require that you use their preferred body shops for repairs. In such a case, you might not have a say on who does the repair work or how much you’ll pay for it.

Add-on services

Another variable that can affect car AC leak repair costs is add-on services. Many mechanics cross-sell to boost their revenues. These include:

  • Refrigerant recharge  

  • Leak detection test  

  • Compressor repair or replacement  

  • Drier or accumulator replacement  

  • Evaporator repair or replacement 

  • Repainting

  • AC regassing

  • Body modification 

  • Car cleaning

Many offer these services as bundles, a.k.a. value packages, so you can take advantage of several services for a flat fee. Others provide maintenance plans to help retain clients. You can always avoid these add-ons, but having them might help in the long run. For instance, they could uncover issues that might become costly problems later. 

Car model and type

Can a car AC be fixed? Yes, but it varies according to the vehicle’s make, model, and year. Older vehicles require more time and effort to repair since their parts might no longer be in production. Luxury cars will almost always be pricier to maintain than economy models because of their design and materials. 

Insurance rates are also usually higher for aged and expensive vehicles because of the required fixing and maintenance. Sometimes the claim might be insufficient to pay for part repair or replacement. In this situation, the insurance company may declare the vehicle as salvage.

Your car’s AC might not be blowing cold air for reasons, such as a Freon leak, a faulty compressor, or a damaged evaporator. The best way to determine the cause is to take it to a mechanic for an inspection.

Car AC prices can widely vary, depending on the part that needs replacement. Compressors are the most expensive.

The time it takes to fix a car’s AC unit will depend on mechanic availability, the severity of the damage, and the vehicle type. Usually, it can take a few hours or a day.

A car’s AC can stop working for many reasons. The most common one is the system is low on refrigerant. It often happens when the AC unit has a leak or the compressor isn't working properly. Other potential causes are a faulty condenser, an electrical problem, or an evaporator issue. If your car's AC isn't working, take it to a mechanic to have it checked.
