9 Common Air Conditioning Myths
Every Ogden Homeowner Should Stop Believing

When the summer heat hits Ogden, Utah, your air conditioner becomes your best friend. But too many local homeowners fall for common air conditioning myths—costing themselves comfort, energy, and money. Don’t let misinformation keep you from staying cool and saving on your utility bills.

Here are nine of the biggest AC myths—and the truth behind them.

1. Bigger AC Units Always Work Better

It’s easy to assume that a larger air conditioner will cool your home faster or more effectively. In reality, an oversized unit can actually make your home less comfortable.

Too much cooling power causes the system to short cycle, meaning it turns on and off frequently. This not only wears out your equipment faster but also prevents your AC from effectively removing humidity—a critical comfort factor during Utah’s hot, dry summers. Proper sizing is key to efficiency and comfort.

2. Cranking Down the Thermostat Cools Your Home Faster

Think setting your thermostat to a super-low temperature will speed up the cooling process? Unfortunately, it doesn’t work that way.

Your AC system cools at a consistent rate, no matter how low the thermostat is set. Dropping the temperature excessively only forces your system to run longer, increasing energy use without faster results.

3. Air Conditioners Only Cool the Air

Many homeowners think their AC’s only job is to lower the temperature. In reality, it also removes humidity from the air—a crucial task in maintaining comfort during those muggy Utah days.

If your home feels sticky or clammy, it may be a sign your air conditioner isn’t operating as it should, and you may need professional service.

4. Closing Vents Saves Energy

It’s tempting to shut the vents in unused rooms to “redirect” cool air where you want it. However, this can actually strain your AC system.

Modern HVAC systems are carefully balanced, and closing vents throws off that balance, increasing pressure in the ductwork. This can lead to leaks, reduced efficiency, and costly damage over time.

5. You Don’t Need Routine Maintenance

Some homeowners believe their air conditioner will run just fine without regular service—until it doesn’t.

Annual tune-ups help prevent breakdowns, extend your system’s life, and improve energy efficiency. In Ogden, with our hot summers, skipping maintenance can leave you sweating when you least expect it.

6. The Location of the Thermostat Doesn’t Matter

The position of your thermostat plays a huge role in how your AC performs.

If it’s placed in a spot that gets direct sunlight or near heat-producing appliances, it can cause false readings—leading to unnecessary cooling cycles. For optimal performance, your thermostat should be located on an interior wall away from heat sources and direct sunlight.

7. Fans Can Replace Air Conditioning

Fans can help circulate air, making you feel cooler—but they don’t actually lower the air temperature.

While ceiling and box fans are great for boosting comfort alongside your AC, they can’t substitute for true air conditioning during Ogden’s summer heat.

8. Air Filters Only Need Changing Once a Year

Dirty air filters make your AC work harder, reducing efficiency and increasing the risk of breakdowns. Waiting too long to change your filter can also worsen your indoor air quality.

In a dry, dusty climate like Ogden’s, it’s smart to check your air filter monthly during the cooling season and change it as soon as it looks dirty—usually every 1 to 3 months.

9. Newer Systems Don’t Need Attention

Even if your AC system is newer, it still needs maintenance and proper use to remain efficient and reliable.

Skipping tune-ups or ignoring small issues can reduce your system’s lifespan and lead to expensive repairs down the road.
