Best service for the AC installation. First class service starting from Paul giving quote till the complete installation. Rodica is great in her communication skills and always available at the end of the phone to answer any questions. Installation guys, father and son duo were excellent, kept me informed about the progress of the installation at all the time, very professional. Couldn't have asked for more. Thank you guys for an excellent service and please keep up doing the great work.

As a facilities manager you need the support and reliability of company's. Denmanair never missed a service, turned up when they said they would, sent the same engineer back. Which just makes my job easy. So Denmanair keep doing what you are doing. Believe me, there are not a lot of company's doing this Service: A/C system maintenance

Denmanair installed last year and now service my elderly parents' air conditioning system and they have been delighted with the quality of the service received. As my parents are both clinically vulnerable it was reassuring for them to see full PPE used and the technician was on time, polite and kept them fully informed throughout as to what had been done. Highly recommended.

We were absolutely delighted with the service offered by Denmanair. We had a/c installed throughout our Victorian house, with tremendous attention to detail and sensitivity to the layout - resulting in virtually no exposed ducting. An excellent job all round, and would highly recommend Denmanair. Service: Install AC

From start to finish Denmanair Ltd were the ultimate professionals. Nothing was too much trouble. They arrived on time each day and were polite and friendly. The product is first class and was installed with the minimum of disruption at a reasonable price. I can not recommend Denmanair Ltd highly enough. Service: Install AC

Since having AC installed by Denmanair Limited some years ago we have continued to receive exceptional support and quality service. The engineers are a credit to the company, being courteous, informative and knowledgeable. They are always on time and never leave any mess behind. I cannot recommend the company highly enough. Many thanks to all at Denmanair

We have been using Denman Air for a couple of years now for the servicing and maintenance of our AC systems. We have found them to be very professional in their approach, competitive with their pricing, responsive and extremely helpful all round. Every interaction that we have had with them has been excellent. During the recent warm spell we found that our system failed leaving half of the building unbearably hot.

We gave them a call and somehow they managed to find a member of their team who was able to attend site to ascertain what issue we were facing. We were looking at a 6-8 week wait for a repair to be completed as they had a full appointment ledger for all of their team. We were fortunate enough that they were able to generate a couple of days of engineer time to assist the public sector premises that we work from. We cannot thank them enough. We have found them to be first class.
