In the age of information, misinformation often spreads like wildfire. That’s why fact checking is a must. When it comes to Heating, Ventilation, and Air Conditioning (HVAC) systems, there is a mass of myths and fake news circulating that can misguide homeowners and lead to potential issues. In this article, we aim to debunk some common misconceptions and set the record straight about HVAC systems. 


  1. Closing vents in unused rooms saves energy. 


One common misconception is that closing vents in rooms not in use will save energy. However, modern HVAC systems are designed to operate efficiently with a balanced airflow. Closing vents can disrupt this balance, leading to increased pressure and strain on the system, potentially reducing its efficiency and causing unnecessary wear and tear. 


Debunking: Keep vents open to maintain proper airflow and system efficiency. Consider investing in a zoning system for more targeted control over individual room temperatures. 


  1. Turning the thermostat to the lowest or highest setting heats or cools the room faster. 


Many believe that setting the thermostat to an extreme temperature will make the heating or cooling process faster. In reality, HVAC systems work at a consistent rate, and adjusting the thermostat to an extreme setting does not speed up the process. 


Debunking: Set your thermostat to a comfortable temperature, and the HVAC system will work efficiently to achieve and maintain that level. 


  1. Regular maintenance is unnecessary. 


Some homeowners may fall into the trap of thinking that HVAC systems do not require regular maintenance. Failure to conduct regular maintenance may result in decreased efficiency, higher energy consumption, and the possibility of system malfunctions. 


Debunking: Regular maintenance, including cleaning filters, inspecting components, and addressing issues promptly, is essential to ensure the longevity and optimal performance of your HVAC system. 


  1. Saving energy is achieved by shutting doors and closing vents in rooms that are not in use. 


The act of closing doors and vents in unused rooms is thought to focus heating or cooling efforts on the areas that are currently occupied. However, it can disrupt the system’s balance, leading to increased pressure and potential damage. 


Debunking: Maintain a consistent airflow throughout your home by keeping doors and vents open. This allows the HVAC system to operate efficiently and evenly distribute conditioned air. 


  1. Bigger HVAC systems are always better. 


Some homeowners think that installing a larger HVAC system will provide better performance. However, oversized systems can lead to short-cycling, inefficient operation, and increased energy consumption. 


Debunking: Proper sizing is crucial for HVAC systems. Consult with a professional to determine the correct size based on your home’s specifications and requirements. 


Navigating the world of HVAC can be challenging, especially when misinformation abounds. By debunking these common myths, we hope to empower homeowners to make informed decisions about their HVAC systems. For reliable information and advice, always consult with HVAC professionals who can guide you toward optimal efficiency and comfort in your home.
