How does insulation impact HVAC system efficiency?

Reduces the workload on HVAC systems
Increases the number of filters needed
Requires more frequent maintenance
Requires specialized HVAC units

The correct answer is: Reduces the workload on HVAC systems

Insulation plays a crucial role in enhancing the efficiency of HVAC (Heating, Ventilation, and Air Conditioning) systems by reducing the workload on these systems. When buildings are properly insulated, they maintain their desired temperature more effectively by preventing the transfer of heat between the interior and exterior. This means that the HVAC system does not have to work as hard to achieve and maintain comfortable indoor temperatures. For instance, in winter, adequate insulation keeps warm air from escaping, while in summer, it prevents hot air from infiltrating. This leads to reduced energy consumption, as the system cycles less frequently. Consequently, the lifespan of the HVAC components can be extended, and energy costs can be minimized. Proper insulation is therefore integral in promoting a more energy-efficient and sustainable operation of HVAC systems without necessitating additional filters, more frequent maintenance, or specialized HVAC units.
