Where do you usually begin when you want to find a high quality local heating and air company? Most of us go to the Internet, the Yellow Pages, or talk to a friend. Sometimes these approaches work, ending in a satisfying customer experience. But too often you can feel your frustration because of a company’s poor performance or follow-up. With so many claims in the marketplace, it's difficult to know which companies are actually delivering on their promises.
Diamond Certified ends the guessing game by ensuring you'll be choosing from ONLY top-rated local companies. We believe in your right to know which local companies are performing at the highest level, and the peace of mind that comes from it.
Why Diamond Certified works for you.
They run the country's most rigorous and accurate rating and certification process of local companies. It starts with the in-depth pass/fail rating of our company's satisfaction, license, insurance, and business practices. Only those rated Highest in Quality earn the prestigious Diamond Certified award. Most simply can't qualify.
But they don't stop there. They continue to monitor our company and complete ongoing customer satisfaction research. Finally, they stand behind our ongoing rating and certification work by backing your purchase with the Diamond Certified Performance Guarantee.
We care about customer satisfaction, and we care about you. We're proud to give you all the information you need to choose with confidence and proud to have been Diamond Certified for SEVEN YEARS RUNNING! And we look forward to the next seven as well.
Please call us with any questions, we would love to chat!
