9 Common Air Conditioner Myths Omaha
Homeowners Need to Stop Believing

At Golden Rule Plumbing, Heating & Cooling, we believe in helping Omaha homeowners make smart, informed decisions about their HVAC systems. Unfortunately, there are a lot of myths floating around about air conditioning—many of which could be costing you money or comfort.

Let’s clear up some of the biggest AC myths we hear.

1. Bigger Is Always Better

It’s easy to think a larger air conditioner will cool your home faster, but that’s not the case. An oversized AC system cycles on and off too frequently, leading to uneven cooling, increased wear and tear, and higher energy bills. The key is proper sizing based on your home’s square footage, insulation, and layout.

2. Turning the Thermostat Way Down Cools Faster

Nope—your air conditioner works at the same speed, no matter the setting. Setting your thermostat drastically lower won’t cool your home any quicker. It just makes your AC run longer, wasting energy. Set it to your desired temperature and let it do its job.

3. Closing Vents in Unused Rooms Saves Money

Closing air vents can actually increase pressure in your system, causing it to work harder and potentially damaging components. Your system is designed to cool your whole home, and blocking vents interferes with that balance.

4. Air Conditioners Only Cool Air

While it’s true that air conditioners lower the temperature, they also reduce humidity inside your home. A properly working AC system in Omaha should keep both the temperature and humidity levels comfortable.

5. Maintenance Isn’t Necessary Until Something Breaks

This is one of the most damaging myths. Regular AC maintenance prevents breakdowns, improves efficiency, and extends the lifespan of your system. Scheduling annual tune-ups with Golden Rule Plumbing, Heating & Cooling helps avoid costly repairs and unexpected system failures.

6. Ceiling Fans Lower Room Temperature

Ceiling fans don’t actually lower the temperature—they simply circulate air, helping you feel cooler through the wind-chill effect. They’re a great complement to your AC, but remember to turn them off when you leave the room to save energy.

7. The Outdoor Unit Doesn’t Need Cleaning

Your outdoor AC unit needs to breathe to work properly. Dirt, leaves, and debris can block airflow, forcing your system to work harder. Make sure the area around your outdoor unit stays clear and clean throughout the cooling season.

8. Newer AC Units Don’t Need Regular Service

Even new air conditioners need maintenance. Skipping tune-ups can cause efficiency issues and void manufacturer warranties. Routine checks help keep everything running smoothly and protect your investment.

9. Air Filters Only Affect Air Quality

While air filters do improve air quality, they also play a major role in your system’s efficiency. A clogged filter restricts airflow, forcing your AC to work harder and increasing your energy bill. Replace filters regularly—typically every 1-3 months, depending on your household.
