When it comes to keeping your home comfortable in Palm Beach County, few things are as important as a reliable HVAC system. Unfortunately, there are plenty of myths and misconceptions out there that can lead homeowners to make costly mistakes. At Duke's Air Conditioning and Heating, we believe in helping our customers separate fact from fiction so they can make the best decisions for their comfort and their budget.
Myth #1: You Only Need to Change Filters Once a Year
A dirty filter can cause your system to work harder, waste energy, and reduce indoor air quality. In our South Florida climate—where humidity and dust can quickly build up—filters should be checked every month and replaced every 1–3 months, depending on your home’s needs.
Myth #2: Bigger HVAC Units Are Always Better
It’s a common misconception that a larger system will cool your home faster and better. In reality, an oversized unit can cycle on and off too quickly, leading to uneven temperatures, higher energy bills, and unnecessary wear. The best system for your home is one that’s sized correctly for your layout, insulation, and cooling needs.
Myth #3: Closing Vents Saves Energy
Many homeowners think shutting vents in unused rooms will save money. In fact, this can disrupt airflow, increase pressure in the ductwork, and strain your system. Balanced airflow is key to efficiency, and that means keeping vents open.
Myth #4: HVAC Maintenance Isn’t Necessary If the System Works Fine
Just because your HVAC system is running doesn’t mean it’s in optimal condition. Preventive maintenance helps catch small issues before they become major repairs, improves efficiency, and extends the life of your system. Skipping tune-ups can cost more in the long run.
Myth #5: Thermostat Placement Doesn’t Matter
Your thermostat is the “brain” of your HVAC system, and its location can greatly affect comfort and efficiency. Placing it near windows, doors, or heat-generating appliances can lead to false readings and uneven temperatures.
