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.
Automotive climate control is our singular craft. Every repair begins with electronic diagnostics and pressure verification — then we service what is genuinely at fault.
Full automotive climate diagnostics and guaranteed mechanical repairs on Miriswatta Road. From cooling failure to compressor, coil and valve overhauls.
Refrigerant recovered, system deep-vacuumed to remove moisture and non-condensables, and recharged with pure virgin refrigerant and synthetic PAG lubricant.
We repair faulty parts—magnetic clutch, pulley bearings, shaft seals, and valve plates—saving you from purchasing expensive complete assemblies.
Tracing why your system loses gas repeatedly. We run high-pressure dry nitrogen holding tests and electronic halogen sniffing so leaks are fixed permanently.
Cleaning, micro-puncture repair, or replacement of front condensers, in-cabin evaporator cores, expansion valves, and receiver-driers.
Dual manifold readings, vent temperature logging, sensor checks, and electrical climate control diagnostics to solve intermittent or weak cooling.
Blower motor servicing, resistor diagnosis, cabin pollen filter renewal, and anti-bacterial vent treatments to eliminate musty smells and restore strong airflow.
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.
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.
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
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.
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.
15+ Years Specialized Automotive Climate Experience
Dedicated service bays on Minuwangoda–Gampaha–Miriswatta Road
We do not dilute our time with oil changes or general mechanical repairs. Our technicians and diagnostic equipment specialize purely in automotive refrigerant cycles.
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.
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.
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.
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.
