Question: 1 / 400

What can be a consequence of improper HVAC installation?

Increased energy efficiency

Higher utility bills

The consequence of improper HVAC installation leading to higher utility bills is a significant concern. When HVAC systems are not installed correctly, they may operate less efficiently than intended. This inefficiency can be due to various factors such as improper sizing of the equipment, inadequate duct sealing, incorrect refrigerant charge, or poor placement of the system. As a result, the system may consume more energy to achieve the desired heating or cooling effect, causing utility bills to rise substantially.

In contrast, correct installation typically enhances the system's performance, leading to lower energy consumption and costs over time, along with improved comfort levels and a longer lifespan for the equipment.
