What is a common HVAC installation error that can reduce efficiency?

Incorrect duct sizing is a significant factor that can lead to reduced efficiency in HVAC installations. Ducts that are too small can restrict airflow, making it difficult for the system to deliver conditioned air effectively throughout the space. This restriction can cause the HVAC system to work harder to maintain the desired temperature, leading to increased energy consumption and wear on equipment. Additionally, improperly sized ducts can create imbalances in the system, resulting in some areas being over-cooled or overheated while others may not receive adequate air at all.

Ensuring that ducts are appropriately sized based on the heating and cooling load calculations for the space is essential for optimal system performance. When ducts are sized correctly, the HVAC system can operate more efficiently, maintaining comfort levels while minimizing energy usage.
