Car Air Conditioning Derby
Warm air, intermittent cooling, compressor noise, or a system that keeps losing gas: a regas only helps when low refrigerant is the actual problem. We diagnose the fault first, then arrange the correct R134a or R1234yf refrigerant service.
Book an assessment if
- Air from the vents is no longer cold
- Cooling works only while driving, not in traffic
- Cold air comes and goes
- Compressor is noisy or doesn't engage
- Cooling faded soon after a previous regas
- Weak airflow or an unpleasant smell
Diagnostic process
- 01
Identify the system
Vehicle, refrigerant type and symptoms confirmed, never assumed from the car's age alone.
- 02
Test the fault
Compressor, pressure, cooling-fan and electrical checks isolate the actual cause.
- 03
Repair and verify
Findings explained, repair carried out, and cooling performance confirmed before handover.
Regas or repair?
A regas is useful only when it addresses the actual problem
Warm air doesn't prove low refrigerant is the only fault. Electrical, compressor, sensor and fan problems can produce similar symptoms and need proper diagnostic testing first. We work with both R134a and R1234yf systems, with the gas type and specified charge confirmed from the vehicle rather than assumed.
Air Conditioning questions
Does my car just need a regas?
Possibly, but warm air alone doesn't prove that. Electrical, compressor, sensor and fan problems can cause the same symptom and need proper testing.
Why did the air con stop working soon after a regas?
A leak may have let the refrigerant escape, or the original problem involved a component or electrical fault rather than gas quantity alone.
Can you find an air-con leak?
Yes, leak detection is available according to the system's condition. Condensers, joints, pipes, seals and evaporators are all possible sources.
Why is it cold only while driving?
Vehicle speed increases airflow through the condenser. Fading in traffic can point to a cooling-fan, airflow or pressure-control problem.
Will a regas fix weak airflow from the vents?
No. Refrigerant affects air temperature, not the volume of air the blower can move. A filter, blower fault or flap issue needs separate attention.
How often should air con be serviced?
There's no single interval that proves every system needs a regas. Performance, service history and measured condition matter more than a fixed date.
