Vehicle Air Conditioning Service & Repair

At Howlett of Lavenham we provide professional vehicle air conditioning servicing, diagnostics and repair for modern petrol, diesel, hybrid and electric vehicles.

Whether your air conditioning is no longer blowing cold, has developed unpleasant smells, or simply needs routine maintenance, we can diagnose and repair the fault properly rather than simply topping the system up and hoping for the best.

We support both R134a and newer R1234yf refrigerant systems used on modern vehicles.

Based in Lavenham, we regularly carry out air conditioning work for customers from Sudbury, Long Melford, Hadleigh and across Suffolk and North Essex countryside.

Car Air Conditioning Regas 

Over time, all vehicle air conditioning systems naturally lose refrigerant gas through seals and joints. Even a healthy system can lose efficiency gradually without obvious symptoms.

If your air conditioning:

• is not as cold as it used to be
• takes a long time to cool the car
• stops cooling in traffic
• mists the windows excessively
• smells damp or musty

then it may be time for an inspection and regas service.

We carry out:

• R134a air conditioning regas - generally vehicles upto 2017 
• R1234yf air conditioning regas - generally vehicles after 2017
• performance testing
• pressure testing
• leak checking
• temperature testing

Air Conditioning Diagnostics & Fault Finding

Many modern air conditioning faults are not simply caused by low refrigerant.

Our workshop can diagnose issues including:

• refrigerant leaks
• failed condensers
• leaking pipework
• compressor faults
• pressure sensor faults
• cooling fan issues
• electrical faults
• climate control system faults

Correct diagnosis matters. Simply recharging a leaking system often results in the air conditioning failing again shortly afterwards.

We prefer to identify the actual cause of the fault so the repair is carried out properly.

Hybrid & Electric Vehicle Air Conditioning 

Modern hybrid and electric vehicles often use specialist electrically driven air conditioning compressors which require the correct oils and servicing procedures.

Using incorrect equipment or oils on these systems can cause expensive damage.

We follow correct servicing procedures for modern hybrid and EV air conditioning systems where applicable.

Why Regular Air Conditioning Servicing Matters 

A properly functioning air conditioning system does far more than simply keep the cabin cool in summer.

It also helps:

• demist windows quickly
• reduce moisture inside the vehicle
• improve driving comfort
• maintain air quality
• reduce strain on system components

Regular servicing can also help identify leaks or component wear before larger failures occur.

Common Signs Your Air Conditioning Needs Attention 

You may need your vehicle air conditioning checked if:

• the air is no longer cold
• cooling performance varies
• the system cycles on and off repeatedly
• there are unusual noises when AC is switched on
• windows mist excessively
• there is a damp smell from vents
• fuel consumption has increased unusually
• the system has not been serviced for several years

Frequently Asked Questions 

How often should car air conditioning be serviced?

Most manufacturers recommend checking or servicing the system every 2 years, although performance issues can appear sooner.

Does air conditioning gas run out naturally?

Yes. Most systems gradually lose refrigerant over time even without major faults.

Can you repair leaks?

Yes. We can diagnose leaks and advise on the correct repair depending on the fault found.

Is air conditioning important in winter?

Yes. Air conditioning helps remove moisture from the cabin and improves demisting performance during colder months.

How long does an air conditioning service take?

A standard service or regas is often completed within around 1 hour, although diagnostic work may require longer.
