Which two conditions can impact the performance of supply and return registers?

• A. Blocked supply registers, dirty HVAC filter
• B. Unsealed ducts, ludicrous placement
• C. Inadequate power, improper size
• D. Weather changes, sunlight exposure

Answer: (A)

Blocked supply registers and a dirty HVAC filter can significantly hinder the performance of both supply and return registers. When supply registers are blocked, the airflow is restricted, leading to uneven heating or cooling in the space. This not only results in discomfort but can also increase energy costs due to the HVAC system working harder to maintain desired temperatures. Additionally, a dirty HVAC filter restricts airflow, causing the HVAC system to operate inefficiently. If the filter is clogged with dust and debris, it can impede the system's ability to pull in air, which affects overall indoor air quality and can lead to further mechanical issues if not addressed. Regular maintenance, including checking and replacing filters and ensuring that supply and return registers are unobstructed, is vital for optimal HVAC system performance.
