Everyone has different experiences.. Few people have effed up systems.. And few go with good systems and just get the servicing done...
My friend went to him with a Nissan 85..
He installed condenser, compressor, made pipes, charged the refrigerant and said thora chalayen set hojaega... And once he brought the car to me for some wiring work. We opened the dashboard for that work so, cooling coil was badly choked... They just charged the refrigerant and took him in confidence that bus itna hi thanda hoga ziada nai...
Anyhows we got those tubes in cooling coils opened.. And it was better...
And few people from our vicinity openly said abubakar is great...
