When your home’s heating or cooling system isn’t working properly, choosing the right HVAC contractor is critical. With so many options available, how do you know who to trust? One of the clearest indicators of reliability, professionalism, and customer satisfaction is a company’s Better Business Bureau (BBB) rating. At D-N-D Services, we’re proud to hold an A+ rating with the BBB, a distinction we’ve earned by consistently delivering quality service to Rockwall and surrounding communities since 1997.
But what exactly does that rating mean for you as a homeowner or business owner? And what should you expect when you choose a BBB A+ rated HVAC contractor? Let’s break it down.
1. Trustworthiness and Accountability
The BBB A+ rating is the highest possible rating and is based on several factors, including how a business handles complaints, its time in business, transparency, and commitment to customer satisfaction. It isn’t bought—it’s earned. At D-N-D Services, we’ve built our reputation on integrity, honesty, and treating every customer like family.
When you hire a BBB A+ rated contractor, you’re working with a company that is committed to doing right by its customers—no shortcuts, no gimmicks, and no pressure tactics. If a simple repair will fix your issue, we’ll tell you. If it’s time for a new system, you’ll get an honest quote and straightforward advice.
2. Highly Trained and Certified Technicians
As a BBB A+ rated HVAC company, we don’t just meet industry standards—we exceed them. At D-N-D Services, all of our technicians are NATE-certified and regularly attend factory training courses to stay current on the latest technology and repair techniques. Our techs are licensed to work on all major HVAC brands, including Carrier, Lennox, Trane, Goodman, York, and more.
When one of our technicians arrives at your home or business, you can expect professionalism, knowledge, and respect. We take pride in doing the job right the first time, whether it’s a small repair, a system replacement, or a complex commercial HVAC job.
3. Comprehensive HVAC Services
An A+ rated contractor should offer more than basic repairs. At D-N-D Services, we provide full-service HVAC solutions for both residential and commercial clients throughout Rockwall and nearby areas including Garland, Greenville, Sunnyvale, Rowlett, Mesquite, and Dallas.
