I have santro club 2004.Last year i installed new ac,Condenser Compressor and pipes.The problem is my car ac puts so much load on the engine that without ac it gives 14 -15 km but with ac it just gives 7-8km.The pick of the car with ac on is very low.And on cng it is very difficult to move the car.The car does not cool well in idle but cooling is good as car gets faster.In one year it has leaked the gas 3 times.What should i do?Should i change the compressor? If yes then which one.Should i try Toyota Duet compressor?Pls guide me.Also mention price of compressor.
