"As an employee of Carrier for over 10 years, I have dealt with Calvert-Jones on several projects over the years. The level of professionalism and service they give displays their true dedication to their customers and vendors. Their dedicated team of professional employees truly does make a difference in every project. I know when I work with them on a project; the job will get done and above all, done right. They take the time to find out what each of their clients needs are and deliver fast, satisfying results. I want to congratulate each and every one of you in celebrating your 60th anniversary.

"Although the relationship between Calvert-Jones and DMR started back in 1969, my personal experience didn't begin until 20 years ago, back in 1987. When the Mark turned your account over to me he said Calvert-Jones would be one of the best customers I'd ever have. He was absolutely right. Over the years Calvert-Jones has grown, but the core values of the company have remained unchanged – you remain dedicated to the highest standards of quality, honesty & integrity. Although some of the faces have changed, the way you do business has not. Under the best of conditions construction projects can be complicated. Over the years we have worked together on many projects that were far from the best of conditions. Calvert-Jones seems to have a knack for those very complicated, critical space, 24/7 operation projects. Those ugly retrofit projects that seem impossible. It is a testament to your company and your employees that so many of your customers hire you to do these difficult projects again and again. I have thoroughly enjoyed having you all at Calvert-Jones as customers and as friends and look forward to the years to come." David Ruf

"I am writing on behalf of the captioned entity and my affiliation/experience with them. I have worked with Calvert-Jones for over 5 years, and my experience overall has been nothing but extraordinary. I would without hesitation recommend this firm to anyone interested in their services. In our area, Calvert-Jones is the preeminent commercial/residential HVAC contractor, and after working with them for 5 years, I now know why. I look forward to my own continued, long term association with these fine folks. Please contact me for any further discussion necessary, I would be glad to assist."

"As a product rep handling dozens of projects at the same time, the best compliments I can give a contractor is that they are fair and easy to work with. Calvert Jones is the perfect example - their project managers make my job easier, and more enjoyable. They take the time to 'sweat the details', and it shows not only in the quality of their projects but also in their relationships with their clients and vendors. I have worked with them on a wide variety of projects, including hospitals, schools, office buildings and churches. Their PM's and install team have the experience to spot potential problems before they begin, and they work towards solutions instead of looking to point fingers."
