BLOG HVAC Myths Debunked: What Every Homeowner Should Know Jun 16, 2025

In today’s world, homeowners constantly seek ways to better manage their home environments, and HVAC systems play a crucial role in achieving that comfort. However, with the plethora of information available, various myths about HVAC systems can lead to confusion. In this article, we will dispel some common HVAC myths and provide clarity to help you make informed decisions about your home’s heating, ventilation, and air conditioning. At Storey’s Services, our goal is to empower you with knowledge so your home remains comfortable all year long.

One of the most prevalent myths is the belief that closing vents in unused rooms saves energy. The logic might seem straightforward: block off rooms that aren’t in use, and you’ll spend less on heating and cooling. However, this can actually have the opposite effect. Modern HVAC systems are designed to distribute air evenly throughout your home. Closing vents can cause an imbalance and strain the system, leading to reduced efficiency and potentially higher energy bills. When airflow is restricted, pressure builds up and could lead to leaks in your ducts, resulting in more energy loss.

Another myth worth debunking is that the bigger the HVAC unit, the better it will perform. While it might make sense to believe a larger system will heat or cool a home more efficiently, the reality is quite different. An oversized unit can lead to issues with humidity and higher consumption of energy. It cycles on and off more frequently, causing wear and tear. Properly sizing your system is essential for optimal operation and efficiency.

Homeowners might also believe that they only need to change their air filters once a year. This is far from true and ignoring regular filter changes can lead to a myriad of problems. A dirty filter restricts airflow, forcing your system to work harder, which can result in increased energy use and heightened risk of breakdowns. Storey’s Services recommends checking your filter every month and replacing it every three months or when it’s visibly dirty.

Some people assume air conditioning systems only need attention when they break down. Preventive maintenance is actually key to extending the life of your HVAC system and ensuring smooth operation. Regular maintenance checks help to catch small issues before they turn into major and costly problems. Our expert team at Storey’s Services advises scheduling regular inspections to maintain optimal performance and efficiency.

Lastly, there's a misconception that thermostats can be set and forgotten. Implementing a programmable thermostat is beneficial, but it requires proper setting adjustments based on your schedule. By programming the thermostat according to when you are home or away, you can significantly reduce your energy usage and save on utility bills. Adjusting it to a higher temperature in the hotter months and a lower one during the colder months when you’re not at home can boost efficiency.

By dispelling these myths, you take a significant step towards better HVAC management. Understanding how your system truly works and taking the proper actions ensures you derive the most benefit while potentially saving on unexpected costs. At Storey’s Services, we are committed to helping you maintain a comfortable home environment through accurate information and reliable service.
