What is included in a 21-Point inspection?
A 21-point HVAC inspection is a comprehensive checkup of a heating and cooling system where O'Brien examines 21 key components to ensure everything is safe, efficient, and working properly. It typically includes inspecting the thermostat, electrical connections, filters, coils, blower motor, refrigerant levels, condensate drain, and safety controls, along with checking for wear, leaks, or airflow issues. The goal is to catch small problems early, improve system performance and energy efficiency, and reduce the risk of breakdowns or costly repairs.
