What is a common result of inadequate insulation in HVAC systems?

Inadequate insulation in HVAC systems frequently leads to increased energy costs. When insulation is insufficient, conditioned air—either heated or cooled—can escape from the intended spaces, causing the HVAC system to work harder to maintain the desired indoor temperature. This added strain on the system results in higher energy consumption, reflected in elevated utility bills.

The system's failure to maintain consistent indoor temperatures often compels it to cycle on and off more frequently, which can lead to additional wear and tear. This situation can create discomfort within the occupied space, as temperature fluctuations become more pronounced. While improved insulation can help achieve consistent temperatures and reduce energy use, the absence of proper insulation primarily drives up energy costs due to the system's inefficient operation.
