9 Common Air Conditioning Myths North Salt Lake
Homeowners Should Stop Believing

When summer hits North Salt Lake, your air conditioner becomes one of the hardest-working systems in your home. But there’s a lot of misinformation out there about how to keep it running efficiently. Believing the wrong advice can lead to high energy bills, unnecessary repairs, and uncomfortable temperatures.

Let’s clear the air! Here are nine common air conditioning myths—debunked.

Myth #1: Bigger AC Units Always Cool Better

It’s easy to think a larger system means more cooling power. In reality, an oversized unit cycles on and off too frequently, leaving your home humid and causing unnecessary wear and tear. Proper sizing based on your home’s square footage, insulation, and ductwork is essential for comfort and efficiency.

Myth #2: Turning the Thermostat Way Down Cools Your Home Faster

Many people crank the thermostat down thinking it’ll cool their home quicker. But your AC works at a constant rate, no matter the temperature setting. Lowering it drastically won’t cool your home faster—it’ll just run longer and waste energy.

Myth #3: Ceiling Fans Lower Room Temperature

Ceiling fans don’t actually cool the air—they circulate it. They create a wind-chill effect that makes you feel cooler, but they don’t change the room’s temperature. Always turn off fans when you leave a room to save energy.

Myth #4: You Don’t Need Annual AC Maintenance

Skipping yearly maintenance might seem like a money-saver, but it often leads to expensive repairs later. Annual inspections catch small issues before they become big ones, extend your system’s lifespan, and improve energy efficiency.

Myth #5: Closing Vents in Unused Rooms Saves Energy

Closing vents might seem like a good way to reduce cooling costs, but it can actually damage your system. Most central air systems are balanced for the whole house. Blocking airflow increases pressure in the ducts, leading to leaks, poor performance, or even system failure.

Myth #6: Air Filters Only Need Changing Once a Year

Dirty filters restrict airflow, forcing your AC to work harder. In homes around North Salt Lake—especially during dusty summer months—filters should typically be checked every month and replaced every 1–3 months for best performance.

Myth #7: AC Units Only Affect Cooling

While cooling is their main job, air conditioners also dehumidify your home. Reducing humidity helps prevent mold and mildew, improves indoor air quality, and makes your home feel cooler without lowering the thermostat as much.

Myth #8: The Location of Your Thermostat Doesn’t Matter

If your thermostat is near a heat source—like direct sunlight or appliances—it can misread your home’s temperature. This can cause your AC to run unnecessarily or fail to cool properly. For optimal results, place your thermostat on an interior wall, away from heat sources and drafts.

Myth #9: All Air Conditioners Are the Same

Not all AC systems are created equal. Features like variable-speed motors, advanced filtration, and energy-efficient technology can make a huge difference in comfort and utility costs. When replacing your system, always compare options and ask about energy efficiency ratings.

Stay Cool, North Salt Lake

Don’t fall for these common myths! Understanding how your AC really works can save you money and keep your home more comfortable throughout Utah’s hot summer months.
