9 Air Conditioner Myths Kaysville Homeowners Need to Stop Believing

At Golden Rule Plumbing, Heating & Cooling, we believe in helping Kaysville homeowners make smart choices about their home comfort. Unfortunately, there are plenty of myths floating around about air conditioners—many of which can lead to higher energy bills, unnecessary repairs, or reduced comfort.

Let’s bust some of the most common AC myths so you can keep your home cool and efficient all summer long.


Myth #1: Bigger AC Units Work Better

Many people assume that a larger AC system means better cooling. However, an oversized unit will short cycle—turning on and off frequently—which wears out parts faster and fails to effectively remove humidity. The right-sized system for your home is always best.


Myth #2: Turning the Thermostat Way Down Cools Faster

Your air conditioner cools at the same rate no matter how low you set the thermostat. Setting it extremely low won’t cool your home faster—it only makes your AC work longer than necessary.


Myth #3: You Don’t Need to Change Filters Often

Dirty filters restrict airflow, making your system work harder. Changing your air filter regularly—typically every 1-3 months—keeps your system running efficiently and improves indoor air quality.


Myth #4: Closing Vents in Unused Rooms Saves Energy

It might seem logical to close vents in unused rooms, but doing so can actually increase pressure in your ducts and reduce system efficiency. Your AC is designed to cool your entire home evenly.


Myth #5: AC Units Only Cool the Air

Your air conditioner also removes humidity from your home. In fact, reducing humidity plays a big role in making your home feel cooler and more comfortable.


Myth #6: Maintenance Isn’t Necessary Unless There’s a Problem

Skipping regular AC maintenance can lead to unexpected breakdowns, higher energy bills, and shorter equipment lifespan. Annual tune-ups help prevent costly repairs and keep your system running at its best.


Myth #7: Ceiling Fans Cool Rooms

Ceiling fans don’t lower room temperature. Instead, they create a wind-chill effect, making you feel cooler. Fans are most effective when you’re in the room—otherwise, they’re just using electricity.


Myth #8: The Outdoor Unit Doesn’t Need Cleaning

Your outdoor unit—also known as the condenser—needs proper airflow to work efficiently. Dirt, leaves, and debris can clog the fins and reduce performance. Cleaning around the unit regularly helps it operate effectively.


Myth #9: Newer AC Units Don’t Need Professional Installation

Even the most advanced AC units can’t perform well if they’re not installed properly. Professional installation ensures correct sizing, airflow, and refrigerant levels, maximizing efficiency and longevity.
