Addressing Common HVAC Myths: What Every Homeowner Should Know Nov 28, 2025

Maintaining an efficient and effective HVAC system is crucial for homeowners, ensuring comfort and reducing energy costs. However, several myths about HVAC systems can mislead homeowners, leading to decisions that might not be beneficial. At College Grove Service Company, we believe that dispelling these myths is essential to help you make informed choices. Here’s what every homeowner should know about common HVAC myths.

One prevalent myth is the belief that setting your thermostat to a higher or lower temperature than desired will heat or cool your home faster. In reality, HVAC systems work at a consistent rate, regardless of the thermostat setting. Rapid temperature changes can overwork your system, increasing wear and tear without speeding up the process. It’s best to set your thermostat to the desired temperature and let the system do its job efficiently.

Another misconception is that closing vents in unused rooms will save energy. This idea seems logical—why heat or cool spaces that aren’t in use? However, modern HVAC systems are designed to balance air distribution. Closing vents can disrupt this balance, causing pressure imbalances and potentially leading to duct leaks. Instead of saving energy, you might end up causing your HVAC system to work harder than necessary, leading to higher energy bills and increased maintenance costs.

Many homeowners believe that regular maintenance isn't necessary if their HVAC system is functioning correctly. This misconception can lead to unexpected breakdowns and costly repairs. Regular maintenance, such as changing filters and checking for leaks, is crucial for the prolonging life and efficiency of your system. It allows professional technicians to catch small issues before they become significant problems, ultimately saving you money and ensuring your home remains comfortable year-round.

A common myth is that the larger the HVAC system, the better it will perform. While it might seem beneficial to have a more powerful system, an oversized unit can lead to inefficient operation and frequent cycling, which causes unnecessary wear. It’s essential to have a system that is appropriately sized for your home for optimal performance and comfort. Consulting with HVAC professionals can help determine the best system based on your specific needs and house size.

Homeowners often overlook the impact of their HVAC system on indoor air quality. A misleading notion is that air filters solely protect the HVAC equipment, but they also play a crucial role in maintaining indoor air quality. Using high-quality filters and replacing them regularly helps ensure that dust, pollen, and other pollutants are removed from the air circulating in your home, promoting a healthier living environment.

Lastly, some believe that running their HVAC system all day is more efficient than turning it off when not at home. While it’s true that constant temperature control prevents your system from working hard to readjust, a programmable thermostat can solve this issue. By adjusting your system’s operation around your schedule, you can efficiently manage your home’s climate without wasting energy.
