It’s easy to pick up bits of advice about your home’s heating and cooling system—from friends, online forums, or even well-meaning family. Unfortunately, some of the most common HVAC “tips” are actually myths that can cost you money, reduce your comfort, and even shorten the life of your equipment. At UBA Heating & Cooling, we believe in empowering our neighbors with the facts. We’re here to debunk the most persistent HVAC misconceptions so you can make informed decisions and keep your system running at peak performance.
System Performance and Efficiency: Clearing Up Confusion
Many homeowners try to outsmart their HVAC system to save money or get faster results, but the system often works best when it’s allowed to operate as designed. Understanding a few key facts about how your equipment functions is the first step toward true efficiency.
Myth: Setting the Thermostat Extremely High or Low Will Heat or Cool Faster
This is one of the most common mistakes we see. The belief is that if you crank the thermostat to 50 degrees in the summer or 90 degrees in the winter, the unit will work harder and reach your desired temperature (say, 72 degrees) more quickly.
The Facts: Your thermostat acts as a simple switch, not an accelerator. Your unit produces heated or cooled air at a consistent, fixed rate. Setting the temperature to an extreme just means the system will run longer until it hits that extreme setting, wasting energy and increasing wear and tear. The best practice is to set your thermostat to a comfortable, steady temperature for optimal performance.
Myth: Closing Vents in Unused Rooms Saves Energy
It seems logical: why pay to heat or cool a room you aren’t using? Many homeowners attempt to save on utility bills by closing off the vents in a spare bedroom or storage space.
The Facts: Your HVAC system is sized for your entire home and relies on balanced airflow. Closing vents creates pressure imbalances in your ductwork, forcing the system to work harder. This leads to several problems:
- Reduced efficiency
- Potential air leaks
- Unnecessary strain on the blower motor

Myth: A Bigger HVAC Unit Is Always Better
When replacing an older unit, some homeowners assume that a larger, more powerful system will deliver faster, more effective comfort.
The Facts: An oversized system is actually less efficient and less effective. If a system is too large, it will “short cycle”—turning on and off frequently. This constant cycling causes:
- Uneven temperatures throughout the home.
- Poor humidity control, a major issue in humid Louisiana.
- Increased wear and tear on components.
- Higher energy bills.
Correct sizing is critical and requires a detailed load calculation that accounts for your home’s specific features.
Essential HVAC Maintenance Facts You Need to Know
Ignoring your system is the most expensive thing you can do. A few simple maintenance practices are necessary to protect your investment and maintain your home comfort.
Myth: You Only Need Maintenance When the System Breaks Down
Filters are often out of sight, so it’s easy to forget about them for long periods.
The Facts: Your filter should be checked and likely changed every 1–3 months. A dirty filter causes significant issues:
- Restricts airflow, forcing your system to work harder.
- Skyrockets your energy bills due to inefficiency.
- Puts unnecessary strain on internal equipment.
If you have pets or allergies, more frequent changes are necessary to keep the air clean and your system running efficiently.
