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.
How often should I service my air conditioner?
We recommend professional servicing at least once every 6 months – especially in Sri Lanka’s tropical climate where dust, humidity, and continuous use put high demands on A/C systems. Annual Maintenance Contracts (AMC) from K.S. Ref Engineers cover this automatically.
What are the signs that my HVAC system needs repair?
Watch for: reduced cooling performance, water leaks from the unit, unusual sounds (rattling, hissing, grinding), bad odours from vents, or a sudden rise in electricity bills. If you notice any of these, call us on 077 320 5858 before a small issue becomes an expensive one.
Do you offer emergency repair services?
Yes. We understand that refrigeration and cooling failures can’t always wait for business hours. Contact us on 077 320 5858 and we will arrange urgent response for critical systems.
Do you work with industrial and commercial clients, not just homes?
Absolutely. Commercial and industrial work is our core strength. We serve factories, hotels, supermarkets, hospitals, offices, leisure clubs, and international organisations including UNICEF. We also handle marine and vehicle A/C systems – capabilities very few firms in Sri Lanka offer.
Are your technicians certified and insured?
Yes. Our lead engineer holds an international certification from German Tec. All senior technicians are qualified and experienced. Business Registration No. WJ 5784 confirms our formal registered status. We are eligible for government tenders and formal procurement processes.
