As a professional in the duct cleaning industry, I have had many opportunities to come in contact with and work with Courtney Eston. I have always found Courtney to be a consummate professional: he is knowledgeable, he keeps in touch with new and upcoming technology, and he remains focused on doing his job well and meeting the customers’ needs and expectations. I have seen that many duct cleaning professionals seek him out for advice and recommendations, especially when they encounter new or difficult projects.

Courtney is well acquainted with the requirements and challenges associated with both commercial and residential duct cleaning, and therefore he knows both what it takes to operate a successful business, and how to go about doing so. I have seen that Courtney has a genuine talent for finding customers, and for establishing their confidence level in him and his services. Having booked the job, he proceeds to go the extra mile to assure that he completes the job as promised and that the customer is satisfied, thus assuring repeat business.

It’s my personal opinion that Courtney is the best at what he does. I have not met anyone in the duct cleaning field who surpasses him in terms of professionalism, knowledge, determination and ability. I believe it could only be to your advantage to establish a business relationship with him.

I am writing this letter in reference to Design Air, Inc. owned by Mr. Courtney Eston. Starting in August 1998, design Air Inc. proceeded to clean the ducts in two buildings for us. One was 97,051 square feet and the other was 22,282 square feet. After completing, I was so pleased with the performance of Mr. Eston and his crew that I had them clean the cooling coils on 41 air handlers and the intake screens. The main stack of H an J building that houses patients are climate controlled by fan coil units in approximately 400 rooms.

Mr. Eston has always been most helpful in providing information and advice about duct cleaning, materials and installation. I have found that his broad range of expertise has been very helpful.

I would not hesitate to hire Design Air, Inc. to do any of my HVAC cleaning. In fact I have plans for another building FY 2000.
