What can extreme outdoor temperatures notably do to HVAC systems?

Extreme outdoor temperatures can significantly impact the efficiency and effectiveness of HVAC systems. When temperatures are very high or very low, these systems must work harder to maintain the desired indoor climate. For example, in extreme heat, the air conditioning units may struggle to cool spaces adequately because the heat load increases, requiring more energy to achieve the same level of cooling. Conversely, in extremely cold conditions, heating systems may have to operate continuously to counteract the loss of heat, which could also lead to inefficiencies.

This added strain can result in a higher energy consumption rate, leading to increased utility bills and potential wear and tear on the system components. Over time, such prolonged stress can decrease the lifespan of the HVAC equipment, and the overall comfort level within the space can diminish. Therefore, extreme outdoor temperatures typically lower the overall efficiency and effectiveness of HVAC systems.
