We conducted a comprehensive home energy audit and efficiency diagnostic for this residence in Texarkana. Our team performed blower door testing using specialized equipment to measure building air leakage and evaluated the performance of both the 5-ton and 1.5-ton HVAC systems. We also documented the existing gas furnace specifications and water heater capacity to assess the home's overall mechanical health. We carefully inspected the attic insulation levels, verifying depths of loose-fill material between 10 and 20 inches to identify thermal gaps. Our technicians performed detailed duct testing and pressure measurements to ensure the ventilation system was functioning properly. These diagnostic procedures provided the necessary data to optimize indoor comfort and improve the property's overall energy performance.
