The customer requested a new air conditioning unit installation after completing renovations that required an upgraded cooling system. We performed a full load calculation to determine the right size for optimal energy efficiency and comfort, then installed a high-efficiency central air unit with a smart thermostat and updated duct connections. After charging the refrigerant and verifying system performance, we ensured the new HVAC system delivered consistent cooling, reduced energy usage, and improved airflow throughout the home. This AC installation not only enhanced indoor comfort but also aligned with modern energy-saving standards.
