Common HVAC Myths Debunked: Separating Fact from Fiction Oct 17, 2025

When it comes to maintaining a comfortable home environment, ensuring your HVAC system functions efficiently is crucial. Yet, myths and misconceptions about HVAC systems often cloud the understanding of homeowners. At Bolen HVAC, we aim to debunk common HVAC myths, helping our customers make informed decisions about their heating and cooling systems, ultimately saving on energy costs and avoiding unnecessary repairs.

A common myth suggests that you should close off vents in unused rooms to save energy. Contrary to popular belief, closing vents can lead to an imbalance in your entire HVAC system. Modern HVAC systems are designed to maintain a consistent airflow throughout your home. When vents are closed, the air pressure increases in the ductwork, which can cause leaks and strain the system. This undue pressure not only increases energy use but can also shorten the lifespan of your HVAC unit. It's best to keep vents open to ensure optimal airflow and efficiency.

Another prevalent misconception is that setting your thermostat to the highest or lowest setting will heat or cool your home faster. HVAC systems work at a consistent rate, regardless of the thermostat setting. Setting the thermostat to extreme temperatures only prolongs the system's run time, increasing wear and tear and driving up your energy bills. Programmable thermostats are a smarter choice, allowing for scheduled temperature changes that align with your daily routine, ensuring comfort and efficiency.

Many believe that changing air filters is not a priority. In fact, regularly changing your air filters is one of the simplest yet most effective maintenance tasks you can do. Dirty filters restrict airflow, causing your HVAC system to work harder than necessary. This strain can lead to increased energy consumption and potential system failures. Aim to check your air filters every month, replacing them every 60 to 90 days, depending on factors such as usage and whether you have pets.

A widely held myth is that maintenance is unnecessary if an HVAC system is running smoothly. Annual maintenance is essential to ensure that your system operates efficiently and reliably. Regular check-ups by Bolen HVAC professionals can uncover minor issues before they escalate into costly repairs. Preventive maintenance also extends the life of your unit and ensures it runs at peak efficiency, saving on energy costs in the long run.

Finally, some homeowners believe that all HVAC service companies are the same. Choosing the right HVAC service provider is crucial for ensuring quality repairs and installations. At Bolen HVAC, we pride ourselves on delivering professional, reliable, and timely service. Our expertise and commitment to customer satisfaction set us apart, ensuring your heating and cooling needs are met with precision and care.
