HIU MAINTENANCE

I have Add Detail service my HIU Heating System every October. I choose October because the heating will already be on for winter and if there is a fault, they can fix the fault at the same time as the service. So far, after several years, I have had no faults. I put this down to the system having a very good service every year. Add Detail are very professional, very punctual and very efficient. They give the heating system a fully comprehensive service at a competitive and fair price. I would recommend Add Detail wholeheartedly.

Justin from Add Detail attended to my flat to install new smart thermostats for my underfloor heating and to help me map the manifold actuators with correct areas of the flat, and also checked my HIU. Justin patiently explained everything. Previously I had horror experiences with a large contractor imposed on us by our building's freeholder/ their managing agent, so I am so glad I have found Justin. Also very fair pricing per hour. Have recommended Add Detail HIU to neighbours in our building needing help as well.

An efficient, punctual, professional and reasonably priced company. Highly recommended. A damaged activator in my HIU unit was identified as the reason why I had no hot water. A replacement was sourced and fitted successfully with a week.

Engineer Justin is a very careful and capable man, he identified our problems which was existed for nearly 7 years. I appreciated his service so much, as we have suffered terrible trouble for so many years. And when Justin was doing the HIU service, he kept very clean, no water dropped to the floor and around, it was amazing!

We contacted Add Detail to have a look at our faulty underfloor heating. Service was prompt and efficient. Initially it was thought that there was a faulty pump which needed to be replaced, but even once that was changed the heating still did not work. Ultimately Justin managed to fix the problem and did not charge for the new pump (this was removed and the old pump returned). Would not hesitate to contact again. An honest trader who charges an honest rate! Thanks again!
