Claim This BusinessD-N-D Services Inc has kept residents comfortable in Caddo Mills and the broader Rockwall area since 1997, building nearly three decades of hands-on expertise in residential and commercial HVAC systems. The company maintains a perfect 5.0-star rating across 120 verified client reviews, a track record that speaks to consistent workmanship and communication. Based at 4770 I-30 Frontage Road, the team responds to calls throughout Kaufman County and surrounding east Texas communities, handling everything from aging system retrofits to new installations.
What distinguishes D-N-D from neighboring contractors is their multi-brand expertise and financing flexibility. As an authorized dealer for Amana, Carrier, and Generac equipment, the company can match homeowners with systems that fit budget constraints without restricting them to a single manufacturer's lineup. Their duct cleaning division deploys industrial-powered equipment, and their indoor air quality assessments address concerns that standard HVAC companies often overlook. Project financing approval can arrive within days, allowing urgent replacements to proceed without delay.
Clients repeatedly mention technician Colton Baker, who replaced a 1980s cooling system at Jody Joiner's daughter's property and handled the entire project from assessment through cleanup within two days of financing approval. For Angela Foster, Colton arrived on time, diagnosed her heating failure immediately, and restored warmth before evening. Reviewer Khalil Martin noted that John guided him through an entire generator installation process from initial consultation in July through completion in November, answering questions at every stage.
Every single reviewer awarded 5 stars, with 120 clients confirming consistent service quality. Technicians Colton and John receive repeated mentions for their responsiveness and clear communication, while several reviewers specifically note the financing team's speed in approvals.
