Separating Fact from Fiction in HVAC Maintenance


Myths and misconceptions often surround the topic of critical systems like HVAC (Heating, Ventilation, and Air Conditioning). At ATS Mechanical, we believe in providing accurate information to our customers. In this blog post, we’ll debunk a common myth related to HVAC maintenance.

Myth: Closing Air Vents in Unused Rooms Saves Energy

Many homeowners believe that closing air vents in unused rooms can help reduce energy consumption and lower utility bills. However, this is a widespread myth that can actually have the opposite effect.

Modern HVAC systems are designed to operate with a balanced airflow throughout the entire ductwork system. When you close vents in certain rooms, it disrupts this balance and creates excessive pressure within the system. This increased pressure can lead to the following issues:

  • Increased energy consumption as the system works harder to overcome the pressure imbalance
  • Potential for ductwork leaks, leading to energy loss and indoor air quality issues
  • Strain on the HVAC system, potentially reducing its lifespan

The Better Solution

Instead of closing vents, it’s recommended to keep them open and maintain proper airflow throughout your home. If there are rooms that you don’t use frequently, consider adjusting the thermostat temperature or investing in a zoning system that allows you to control the temperature in different areas of your home independently.

At ATS Mechanical, we prioritize educating our customers on best practices for HVAC maintenance and energy efficiency. By dispelling myths and providing accurate information, we aim to help homeowners make informed decisions that can save them money and prolong the life of their HVAC systems.
