Debunking HVAC Myths: What Homeowners Need to Know Dec 28, 2025

The world of HVAC is filled with misconceptions and myths that can steer homeowners in the wrong direction. Understanding the truth behind these myths is crucial for efficient home heating and cooling. At EPS Heating and Cooling LLC, we aim to empower our clients with the right information so they can make informed decisions about their HVAC systems.

One common myth is that closing vents in unused rooms can save energy. This belief persists from the idea that less airflow equates to less energy use. In reality, modern HVAC systems are designed to balance air distribution throughout the home. Closing vents can lead to an imbalance in airflow, causing the system to work harder to maintain the desired temperature. This could increase energy consumption and lead to wear and tear over time, potentially requiring more frequent HVAC maintenance.

Another myth we often encounter is the assumption that the bigger the HVAC unit, the better it will be at cooling or heating your space. While it might seem logical to assume a larger system would be more effective, this is not the case. An oversized unit can lead to uneven temperature regulation and poor humidity control, leading to discomfort. It may also cycle on and off more frequently, thereby reducing its lifespan. Proper sizing based on the specific needs of your home is critical, and it’s best determined by an experienced HVAC professional.

Some homeowners believe that routine maintenance is unnecessary unless there’s a noticeable problem. This myth can prove costly in the long run. Regular HVAC maintenance is key to keeping your system running efficiently and prolonging its lifespan. By scheduling periodic check-ups, homeowners can avoid unexpected breakdowns and costly repairs. Maintenance tasks like filter changes, coil cleaning, and thermostat checks help in maintaining system efficiency.

Additionally, programmable thermostats often come with their share of myths, such as the claim that they don't save energy. A wisely programmed thermostat can significantly reduce energy bills by adjusting the home’s temperature according to your daily schedule. Setting your thermostat to a lower or higher-than-comfortable temperature when you are away or asleep can reduce energy use substantially. Modern programmable thermostats are intuitive and can be set to follow routines that suit your lifestyle, optimizing both comfort and energy savings.

Many people also erroneously believe that energy efficiency improvements will immediately reflect on their bills. While upgrades do contribute to lower bills, the extent varies based on several factors, including home insulation, usage patterns, and even geographical location. Consistent usage practices along with upgrades are essential in realizing these savings over time.

Contrary to the myth that air conditioners only cool the air, they are also responsible for removing humidity. This is especially important in warm climates where high humidity levels can cause discomfort. If your air conditioner isn’t removing humidity effectively, it may indicate a system malfunction or the need for an upgrade.

In conclusion, staying informed about your HVAC system can help improve its efficiency and lifespan. EPS Heating and Cooling LLC is here to assist you with expert guidance, ensuring you reap the benefits of a well-maintained HVAC system. By debunking these myths, you can make smarter decisions for your home’s comfort. Feel free to reach out to our team for professional HVAC services tailored to your needs.
