Radiators, thermostats, water pumps and hoses: goodbye to overheating.
See detailsWhy is the air conditioning barely cooling?
The most common cause is gradual refrigerant loss — every circuit loses a little each year — followed by leaks, a dirty cabin filter or a failing compressor. A regas with leak detection identifies which is your case.
Advice we give everyone: run the air conditioning in winter too, a few minutes a week. The compressor is lubricated by its own circuit, and six months idle is the perfect recipe for July arriving with no cold air. As for engine cooling, if the temperature needle climbs above normal or the coolant level drops on its own, do not let it slide: between a thermostat in time and a head gasket there is an enormous difference in cost.
Gas top-up vs. circuit repair: what does your A/C need?
Quick answer: if the system lost gas gradually over several years, a full regas solves it; if it empties in weeks, there is a leak to repair first.
| Criterion | Full regas | Repair + regas |
|---|---|---|
| Gas loss | Slow, natural for the circuit | Fast (days or weeks) |
| Procedure | Recovery, vacuum and exact charge | Leak detection, repair, then regas |
| Result | A/C like new for years | Definitive fix |
| Mistake to avoid | — | Regassing again and again without fixing the leak |
We always pressure-test before charging: if the circuit leaks, we tell you with a repair quote — we do not sell repeat regasses.
Frequently asked questions
How often does the A/C need regassing?
A healthy circuit loses a little gas naturally; a regas every 3–5 years is typical. If you need one every summer, there is a leak to find.
Which gas does my car use?
Cars before ~2017 usually use R134a; modern ones R1234yf. We check the engine bay label and use the corresponding equipment.
Why does the car’s air smell bad?
Usually a saturated cabin filter or microorganisms on the evaporator. Fixed with a filter change and a ventilation circuit cleaning treatment.
What do I do if the car overheats in a traffic jam?
Turn off the A/C, set the heater to maximum to help shed heat and, if the needle keeps climbing, stop the engine and call us. Driving an overheated engine multiplies the damage.
