UES provided us with a tailor-made solution to improving the ventilation in our office. They cleverly adapted the existing ductwork in the ceiling to save time and money for the new installations. We are delighted with the new filtered fresh air, and the staff have welcomed our new back-to-the-office plans.

UES has developed a great understanding of our infrastructure. They react quickly, and their staff are highly knowledgeable. I have recommended them to several people.

Matt Johnstone

UES have proven across multiple projects that they are an efficient and reliable contractor who consistently works to an exceedingly high standard. First Bus always trusts UES to get the job done swiftly and timely, and the savings we have made from their installations have often quickly surpassed the cost of the initial investment.

UES are experts at reducing heating costs through carbon reductions technologies and I am looking forward to working with them again soon.
