Why Sri Lanka's Best Companies Choose K.S. Ref Engineers
For 25 years, we have earned trust not by promising the most – but by consistently delivering it. Here is what makes us different.
Our proprietor K. Chathura Kolitha Perera holds a professional certification from German Tec – one of the world’s leading HVAC and refrigeration training institutions. While most local competitors carry only Sri Lankan trade qualifications, our technical knowledge is benchmarked against international standards. That means better diagnosis, better installations, and fewer callbacks.
We know that a failed air conditioner or refrigeration system cannot wait. Whether it is a home unit, a hotel facility, or an industrial cold room – K.S. Ref Engineers responds quickly and works efficiently to get your system back up and running. Our clients include UNICEF Sri Lanka, CIC Holding PLC, and Taprospa Resorts – organisations that simply cannot afford delays. We hold ourselves to the same standard for every client, big or small.
Before any work begins, you receive a clear, itemised quotation covering parts, labour, and timeline. We explain exactly what needs to be done and why – in plain language, not technical jargon. No surprise charges at the end of the job. No upselling you on services you don’t need. Just fair, honest pricing that reflects the quality of work we deliver. That transparency is one of the reasons our clients have trusted us for over two decades.
