In Florida, your HVAC system works harder than almost anywhere else. Unfortunately, common HVAC myths can cause your system to waste energy, break down prematurely, and increase your monthly costs. At Bayonet Plumbing, Heating & Air Conditioning, we’re here to set the record straight and help you avoid costly mistakes that hurt comfort and efficiency.
Myth #1: Duct Tape Works for Sealing Ductwork
Despite its name, duct tape doesn’t belong anywhere near your HVAC ducts. In Florida’s heat and humidity, the adhesive quickly breaks down, leaving gaps that leak conditioned air into attics or crawl spaces. Those leaks force your AC to run longer, driving up energy bills and straining your system. Even small leaks can waste 20% or more of cooled air. The right fix is professional duct sealing using mastic or foil-backed tape rated for HVAC systems.
Myth #2: Turning the Thermostat Way Down Cools the Home Faster
When your home feels hot and sticky, it’s tempting to crank the thermostat down to 60°F. However, it doesn’t cool your house any faster. Air conditioners work at a steady rate, so setting it lower just makes your system run longer and use more electricity.
Every degree you drop below your standard setting can increase cooling costs by 3–5%. Instead, keep your thermostat around 76-78°F when you’re home and raise it slightly when you’re away. Installing a smart thermostat can automate temperature changes for comfort and savings. It’s one of the simplest ways to avoid high energy bills while staying cool in Florida’s climate.
Myth #3: HVAC Maintenance Isn’t Necessary
If your system seems to be running fine, it’s easy to assume heating maintenance in Marco Island can wait—but skipping tune-ups is a costly mistake. Over time, dirt buildup, clogged drains, and low refrigerant levels cause your system to lose efficiency and wear out faster.
Without maintenance, your HVAC can waste up to 10% more energy each year. That means higher bills and a greater risk of breakdowns during the peak of summer. Regular service helps prevent expensive repairs and extends your equipment’s life.
Myth #4: Closing Vents in Unused Rooms Saves Energy
It might seem smart to close vents in rooms you don’t use, but doing so actually increases duct pressure and reduces system efficiency. Restricted airflow can cause leaks, frozen coils, or motor damage—each of which can lead to expensive repairs.
Your HVAC system is designed to move air evenly throughout your home. When you block that airflow, you force it to work harder, wasting energy and shortening its lifespan. If you want better temperature control, consider a zoning system or smart dampers that let you control different areas individually without harming efficiency.
The Bottom Line: HVAC Myths Waste Energy and Money
Believing HVAC myths won’t save you money—it will cost you more in energy, repairs, and comfort. From leaky ducts to thermostat mistakes, small misunderstandings can add up to big expenses over time.
