About DNR A/C & Heating LLC
DNR A/C & Heating LLC operates as a licensed HVAC contractor serving residential clients throughout Houston, Texas. With more than a decade in business, the company has built a track record reflected in its perfect 5.0-star rating across seven client reviews. The team holds certifications in both heating and air conditioning technical work, offering installation, repair, and maintenance services across major equipment categories including split systems, package units, and emerging technologies like UV air purification. Homeowners in neighborhoods spanning the Heights, Memorial, and Galleria areas have relied on this contractor for both routine seasonal maintenance and urgent equipment failures.
What distinguishes DNR A/C & Heating from many independent contractors is their commitment to around-the-clock availability paired with financing options that ease larger investment decisions. The website references a comprehensive service model where one call addresses not just the primary heating or cooling system but also associated components including drain lines, thermostats, electrical switches, and flue pipes. This holistic approach means homeowners avoid coordinating multiple subcontractors when interrelated problems surface. The company emphasizes their certified technical credentials alongside transparent pricing, a combination acknowledged in multiple five-starreviews that cite straightforward explanations of problems and costs before work begins.
Client feedback reveals specific technicians making impressions beyond the work itself. Reviewer Liz Zoellick specifically names Damiany as honest and reliable, noting he goes out of his way to help. John Matos described his technician as knowledgeable and respectful of the home, providing maintenance guidance after completing the repair. Cass P. highlighted rapid response and friendly demeanor during an urgent situation, reinforcing the company's stated emphasis on timely service. These named encounters illustrate how technical competence translates into homeowner confidence during stressful mechanical failures.
