9 Common AC Myths Bountiful
Homeowners Need to Stop Believing

When the summer heat hits Bountiful, Utah, your air conditioner becomes your home’s best friend. But there’s a lot of outdated advice and misinformation floating around about how to use and care for your AC system.

At Golden Rule Plumbing, Heating & Cooling, we’ve heard it all—and we’re here to clear the air. Here are nine of the biggest air conditioning myths that could be costing you comfort and cash.

Myth #1: The Bigger the AC, the Better

It might seem logical—bigger means more power, right? Not when it comes to air conditioners. An oversized system will cool your home too quickly without properly removing humidity, leaving your space feeling cold and clammy. Plus, it’ll cycle on and off more frequently, leading to higher energy bills and premature wear.

✔️ The Golden Rule Tip:

Work with a professional to get a system that’s sized just right for your home’s square footage and layout.

Myth #2: Cranking the Thermostat Cools Your Home Faster

Turning your thermostat way down won’t speed up the cooling process—it simply makes your system run longer. Air conditioners cool at a constant rate, no matter what temperature you set.

✔️ The Golden Rule Tip:

Set your thermostat to a reasonable temperature (around 78°F in summer) and be patient.

Myth #3: Closing Vents in Unused Rooms Saves Energy

Many homeowners think shutting vents in unused rooms will redirect airflow and cut costs. In reality, this can throw off your system’s balance, forcing it to work harder and potentially causing duct leaks.

✔️ The Golden Rule Tip:

Keep vents open and ensure your entire system is running efficiently.

Myth #4: Maintenance Is Optional

Think you can skip annual AC tune-ups? Think again. Neglecting maintenance can lead to costly breakdowns and shortened system lifespan.

✔️ The Golden Rule Tip:

Schedule a yearly maintenance visit with our HVAC pros in Bountiful to keep your system running smoothly.

Myth #5: Air Filters Only Need Changing Once a Year

Waiting too long to replace your air filter restricts airflow and makes your system work overtime. In Bountiful’s dry, dusty climate, dirty filters can clog fast.

✔️ The Golden Rule Tip:

Check your filter every month and replace it at least every 90 days—or sooner if it looks dirty.

Myth #6: Ceiling Fans Cool a Room

Ceiling fans don’t actually cool the air—they just create a wind-chill effect that makes you feel cooler.

✔️ The Golden Rule Tip:

Turn off fans when you leave the room to save energy.

Myth #7: Thermostat Placement Doesn’t Matter

Where your thermostat is installed can have a major impact on comfort and efficiency. Placing it near windows, vents, or heat sources can cause false readings.

✔️ The Golden Rule Tip:

Position thermostats in a central location away from direct sunlight and drafts.

Myth #8: Newer AC Units Don’t Need Maintenance

Even the most advanced, energy-efficient systems require regular checkups to perform their best.

✔️ The Golden Rule Tip:

Protect your investment with annual maintenance from trusted Bountiful HVAC technicians.

Myth #9: DIY Repairs Are Cheaper and Easier

While DIY might save a few bucks upfront, it can lead to costly mistakes, safety hazards, and even void your warranty.

✔️ The Golden Rule Tip:

Always leave repairs to licensed, experienced professionals like our team at Golden Rule Plumbing, Heating & Cooling.
