When the warmer months arrive in the Scottish Borders, a fully functioning air conditioning system can make all the difference to your driving experience. At A&E Garage Services, we help drivers across Earlston, Kelso, Selkirk, St Boswells, Melrose, and Galashiels keep their vehicles comfortable and road-ready all year round — and your car's air conditioning is a bigger part of that picture than many people realise.
How Does a Vehicle Air Conditioning System Work?
Your car's air conditioning isn't just a luxury — it's a complex system that works hard every time you press that button. At its core, it uses a refrigerant gas that cycles through a series of components: the compressor, condenser, receiver dryer, expansion valve, and evaporator. The refrigerant absorbs heat from inside the cabin and releases it outside, leaving you with cool, comfortable air.
It sounds straightforward, but each of those components is under constant pressure and subject to wear over time. That's why regular vehicle servicing should always include a check of your air conditioning system — not just your engine, tyres, and brakes.
Why Air Conditioning Systems Need Regular Attention
One of the most common misconceptions we hear at A&E Garage Services is that air conditioning only needs attention when it stops working. In reality, by the time you notice a problem, the system may already have been underperforming for some time.
Here's what can go wrong:
Refrigerant leaks — Over time, even a healthy system loses a small amount of refrigerant through natural seepage. A system that's low on refrigerant won't cool effectively and can place extra strain on the compressor.
Bacterial build-up — The evaporator coil is a warm, damp environment — ideal conditions for bacteria and mould to develop. This is often the cause of that musty smell you notice when you first switch the air conditioning on.
Compressor wear — The compressor is the heart of the system. If it's not properly lubricated (which happens when refrigerant levels drop), it can fail — and compressor replacement is one of the more costly vehicle repairs you'll want to avoid.
Electrical faults — Modern vehicles rely on sophisticated electronics to manage the air conditioning system. A fault here may not trigger a warning light, which is why proper diagnostics equipment is essential.
What Does an Air Conditioning Service Involve?
At A&E Garage Services, our air conditioning service uses professional-grade equipment to recover, recycle, and recharge your refrigerant to the manufacturer's specification. We also inspect the system for leaks, test the compressor operation, and carry out a full pressure check to make sure everything is working as it should.
If we identify any underlying issues, we'll discuss your options clearly before carrying out any vehicle repair work - no surprises, no hidden costs.
Air Conditioning and Your MOT
While a working air conditioning system is not a direct MOT requirement, faults within the system can sometimes contribute to issues that are — such as a damaged compressor belt or an electrical problem affecting other systems. During your MOT, our technicians carry out a thorough inspection of your vehicle, and we'll always flag any air conditioning concerns we spot, even if they fall outside the test criteria.
If you're due an MOT and haven't had your air conditioning checked in the last couple of years, it's a great time to book both together and save yourself a return visit.
