Temperature Design, LLC

We provide residential and commercial heating and cooling services in Mooresville, Lake Norman, and surrounding communities, including Cornelius, Davidson, and Huntersville. For more than 25 years, we have focused on helping homeowners and businesses create comfortable indoor environments. We listen carefully to each customer’s concerns and recommend customized options based on needs such as indoor air quality, allergy management, noise reduction, energy efficiency, and cost.

Our experienced technicians, installation crews, and sales staff handle HVAC system analysis, installation, repair, and ongoing maintenance. We work with modern heating, air-conditioning, and ventilation equipment, and we continually invest in industry training and continuing education for our team. Our process begins with a thorough system assessment, followed by a clear explanation of the problem and available solutions. After completing a repair whenever possible, we test the system for safe and efficient operation and answer any questions. We also offer 24-hour emergency HVAC service and seasonal maintenance plans that may include filter replacement, ductwork inspection, system tune-ups, efficiency testing, and safety checks.

For new installations, we offer free in-home estimates, professional system sizing, equipment from leading brands, manufacturer warranties, and flexible financing options. We also provide installation, service, and maintenance for a wide range of geothermal products. We are a WaterFurnace dealer because we value the brand’s commitment to innovation, quality, and customer service. Above all, our goal is to provide personalized service centered on each customer’s comfort needs and to maintain the strong reputation our team has built throughout the Lake Norman area.
