Car A/C Specialists.Diagnosed & Repaired Right.
Automotive air-conditioning diagnosis, gas recharging, and precision mechanical repairs in Gampaha. From compressor overhauls and electronic leak detection to complete climate restoration — we identify the true root cause before turning a single bolt.
Engineered Care for Every Car A/C Component
Automotive climate control is our singular craft. Every repair begins with electronic diagnostics and pressure verification — then we service what is genuinely at fault.
- 01
A/C Gas Recharge
Refrigerant recovered, the system evacuated and recharged to the specification for your vehicle, then checked under pressure.
- Correct refrigerant type and quantity for the vehicle
- System vacuum to remove air and moisture before charging
- High- and low-side pressure check with manifold gauges
- 02
Compressor Repair
Inspection of the compressor, clutch and pulley bearing — repairing the faulty part where that makes sense instead of replacing the whole unit.
- Noise, clutch engagement and bearing checks
- Clutch, bearing and seal repairs
- Replacement when a repair is not the right option
- 03
Leak Detection
Tracing why a system keeps losing gas — across hoses, joints, seals and components — so the leak is fixed rather than refilled again.
- Pressure testing of the refrigerant circuit
- Inspection of hoses, O-rings, joints and service valves
- Repair of the leaking part before recharging
- 04
Condenser & Evaporator Service
Cleaning, repair or replacement of the condenser, evaporator, expansion valve and receiver-drier when they limit cooling.
- Condenser and receiver-drier replacement
- Evaporator and expansion valve servicing
- Cooling check after reassembly
- 05
A/C Diagnosis
A structured check of pressures, electrical controls, sensors and vent temperature to find the actual cause of weak or intermittent cooling.
- Vent temperature and airflow checks
- Electrical, sensor and control checks
- A clear explanation of what was found before work begins
- 06
Airflow & Cabin Air
Blower motor, cabin filter and vent servicing for weak airflow and musty smells from the vents.
- Cabin filter replacement
- Blower motor and resistor checks
- Vent and duct cleaning for odours
Unsure What Is Causing The Problem?
Describe your symptoms to our technicians on WhatsApp. We will advise whether a simple gas recharge, leak check, or full diagnosis is required before you visit.
Six Components. One Closed Thermodynamic Loop.
Automotive air conditioning moves heat out of your cabin by circulating pressurized refrigerant through a closed circuit. Select any component below to see its function and common failure signs.
Compressor
Pumps refrigerant around the system and raises its pressure. It is the heart of the circuit — when it stops, cooling stops.
Failure Signs to Watch For
- Noise when the A/C is switched on
- A/C clutch not engaging
- No cold air at all
Workshop Testing Standard
We check high/low gauge pressures, magnetic clutch coil resistance, and bearing play before determining whether a repair or overhaul is needed.
A Dedicated Car A/C Specialist in Gampaha
Janaka Auto AC is an automotive air-conditioning workshop situated on the Minuwangoda–Gampaha–Miriswatta Road. Vehicle climate control is our full-time focus — not a sideline to general mechanical servicing.
Passenger sedans, SUVs, and commercial vans come to our covered service bays for everything from precision gas recharges to compressor overhauls and electronic leak detection. Our approach is grounded in craft: diagnose the root failure first, explain it clearly to you, and execute the repair with durable components.

Why Vehicle Owners Rely on Janaka Auto AC
- 01
100% Automotive A/C Focus
We do not dilute our time with oil changes or general mechanical repairs. Our technicians and diagnostic equipment specialize purely in automotive refrigerant cycles.
- 02
Diagnosing Root Causes, Not Just Gas Top-ups
If your system repeatedly loses gas, topping up is a temporary cover-up. We run electronic leak testing and vacuum holds to fix the real source of the leak.
- 03
Repairing Over Costly Replacement
Whenever mechanically sound, we overhaul compressors, renew bearings, and replace O-rings. We never force expensive complete unit replacements if a repair solves the problem.
- 04
Direct Technician Consultation
Speak directly with the workshop technicians by phone or WhatsApp. We explain what was found, what is required, and give you clear pricing before work begins.
- 05
Six-Day Service Availability
Open Tuesday – Sunday from 8:30 AM – 6:00 PM (closed Mondays). Convenient weekend availability so you do not have to disrupt your work schedule.
