About KMI A/C & Heating
KMI A/C & Heating operates from 1701 E. Sunset Blvd. in Celina, holding Texas license TACLA022418C. The company maintains a near-perfect 4.9-star rating across 75 customer reviews, reflecting nearly a decade of continuous service to Celina residents. Homeowners throughout Collin County trust this team for both routine seasonal maintenance and unexpected system failures, with the majority of review authors noting multi-year relationships spanning four to nine years.
This contractor provides comprehensive heating and cooling solutions backed by a network of service agreements designed to keep residential systems operating efficiently year-round. The company extends a 15% discount to educators, first responders, military personnel, and senior citizens, recognizing community members who serve the public. Flexible financing options allow homeowners to address replacement needs without delaying critical comfort upgrades.
Recent customer experiences highlight technicians who arrive prepared and communicate clearly. Lea L.'s duct cleaning project involved technicians George, Austin, Levi, and Kyle, who protected furniture throughout the multi-day process and corrected an unexpected airflow issue without additional charges. SueClark's AC replacement was completed in four hours instead of the scheduled six, with technicians respecting floor coverings and cleaning thoroughly before departure. Don Drysdale's system required only wire replacement after KMI's consultation revealed the issue, cutting an initial $1,400 estimate nearly in half.
What Customers Say
All 75 reviewers award 4 or 5 stars, with multiple customers specifically naming technicians George, Austin, and Joe as knowledgeable and trustworthy. Positive reviews consistently mention transparent pricing and thorough explanations, while the sole 1-star review cites communication gaps rather than workmanship quality.
