“This letter is to thank you for a job well done, outstanding cooperation and extra efforts during the course of the entire Air Conditioning Construction Phase. We know this was a difficult project, due to the constraints of budget, complexity of the existing structure and tight physical space. You kept all established deadlines, worked very well with the entire construction team and produced a project that had 0 items that needed a follow up. It's been a total pleasure to work with you and your staff on this project and I hope to have the opportunity to work with you and your company in the future.”
