Mrs Thomson - April 2022

Mark has now installed new boilers for us at two properties that we own. He works very hard and shows great attention to detail, making sure that all the pipework, etc. is installed correctly and that every thing is functioning as it should. We would definitely recommend him and will certainly use him in the future.

Mrs Smith - March 2022

Fantastic service. Mark came out despite being busy, and comes highly recommended. He showed me what the problem was and explained everything to me. I'm definitely sticking with this company for life!

Mr Tait - Feb 2022

Just moved to the Ardrossan area and needed a boiler service. Randomly picked DTSN’s number from a quick Google search……and so glad I did. Mark was timely, courteous, professional and didn’t try any unnecessary up-selling. He also took the time to explain what he was doing and happy to answer any questions I had. Will definitely be using him again……excellent value for money.

Mr Dunlop - Feb 2022

I had a problem with my boiler showing L2 fault. DTSN was recommended. I spoke to Mark who arrived soon after despite him having a busy schedule. Mark was professional, friendly and efficient. Fixed the problem quickly and explained the problem to me in layman's terms, also price was very reasonable. I would highly recommend.

Carly - Jan 2022

Needed a radiator fitted before we could finish decorating a room so quickly went on Google and chose Mark on a whim - and so glad we did. Mark came on time, sent a quote by the end of the day and had the job finished a few days later. What really amazed us though was that after explaining general the issues we’ve had with the whole heating/hot water system and the peculiar method we’ve got in place to manage both, Mark seemed totally unfazed and corrected this too (this is after 2 different engineers AND an electrician have told us we’d need to spend an elaborate amount to correct it) Would definitely recommend DTSN for any heating concerns!!

Mr Craine - Jan 2022

My boiler was losing pressure, and after phoning Mark he quickly diagnosed the issue. He was out quickly and resolved it there and then. I will be contacting Mark on a yearly basis now to service my boiler - friendly service and very reasonably priced. I also had a separate issue with a radiator and he helped me at no additional cost!

Ms Kenmore - Jan 2022

Great service from Mark. My radiator hadn’t been working for a while and he sorted it very quickly. Very competitive price too. Won’t hesitate to call DTSN in the future. Very efficient and very nice guy.
