Mr McIntyre - May 2023

Excellent, first class service, from a professional who takes a pride in what he does, all at a great price. Thanks, will be using again in the future.

Mr Millar - April 2023

Mark's been servicing my boiler for years and has just installed a new one. Honest recommendations, competitive prices and first class work every time. I wouldn't think of going anywhere else.

Mr Wilson - Feb 2023

Very efficient and pleasant service at a reasonable price.

Mrs Cooke - Dec 2022

Mark took the time to phone me late at night when no heating or hot water and very patiently talked me through getting the boiler running again. It was below freezing temperatures that night so really appreciated that he done that, especially being outwith his working hours. Would definitely recommend this company

Mrs B - Nov 2022

Fantastic service. Fixed my boiler & also did a safety check which I wasn't expecting. Thank you so much

Mr Collins - Oct 2022

Mark and his associate were 5 star.
No hot water, no heating, boiler on the blink after been serviced by another company three months ago. Phoned DTSN came out same day. Diagnosed quickly and sorted promptly. Cannot recommend DTSN enough. Thank you Mark.

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.
