5 HVAC Myths That Cost Homeowners Money & Comfort

When it comes to heating and cooling your home, there’s a lot of information out there—but not all of it is accurate. Misinformation can lead to higher energy bills, frequent AC repairs, and even premature system replacements. At Childress Heating & Cooling, we’re here to set the record straight and ensure your HVAC system operates at peak efficiency year-round.

Let’s debunk five of the most common HVAC myths so you can make informed decisions about your home’s air conditioning and heating system.

Myth #1: Closing Vents in Unused Rooms Saves Energy

Many homeowners believe that shutting vents in rooms they don’t use will reduce energy consumption and lower utility bills. However, this actually does more harm than good to your AC system.

The Truth: Your HVAC system is designed to distribute air evenly throughout your home. When you close vents, it disrupts airflow, increasing pressure in the ductwork and forcing your system to work harder. Over time, this can lead to higher energy bills, reduced efficiency, and even damage to your AC unit.

What to Do Instead: If you want to save energy, consider upgrading to a zoned HVAC system that allows better temperature control in different areas of your home. Regular AC maintenance also ensures your system runs efficiently without overworking itself.

Myth #2: Bigger AC Units Provide Better Cooling

Many people think that installing the largest air conditioner possible will keep their home cooler. Unfortunately, an oversized AC system can create more problems than solutions.

The Truth: Air conditioners don’t just cool your home; they also remove excess humidity. An oversized AC unit cools the air too quickly, cycling off before it has a chance to remove moisture. This leads to a damp, uncomfortable home and higher humidity levels—a breeding ground for mold and mildew.

What to Do Instead: Work with a professional HVAC technician to choose the right AC size for your home. Childress Heating & Cooling performs load calculations to determine the perfect system for energy-efficient, balanced cooling.

Myth #3: You Only Need to Change Your Filter Once a Year

Many homeowners overlook air filter maintenance, assuming it’s not essential to their AC’s performance. However, a dirty air filter can significantly impact airflow, efficiency, and indoor air quality.

The Truth: Your HVAC filter should be changed every 1-3 months—or more frequently if you have pets, allergies, or live in a high-pollen area. A clogged filter forces your AC system to work harder, increasing energy consumption and the risk of breakdowns.

What to Do Instead: Set a reminder to check your filter monthly and replace it as needed. A maintenance plan with Childress Heating & Cooling includes routine filter checks and replacements to keep your system running smoothly.

Myth #4: HVAC Maintenance Isn’t Necessary If Your System Works Fine

It’s easy to think that if your AC is cooling your home, there’s no need for a tune-up. But preventative maintenance is key to avoiding costly repairs down the road.

The Truth: HVAC systems accumulate dirt, dust, and wear and tear over time. Skipping annual maintenance can lead to reduced efficiency, increased energy bills, and even premature system failure. A well-maintained AC unit lasts years longer than a neglected one.

What to Do Instead: Schedule a seasonal AC tune-up to catch minor issues before they become expensive repairs. Our Childress Heating & Cooling Maintenance Plan ensures your system is always in top shape, helping you save money and avoid emergency breakdowns.

Myth #5: Cranking the Thermostat Cools Your Home Faster

When the summer heat is unbearable, many homeowners turn their thermostat way down, thinking it will speed up the cooling process. Unfortunately, this doesn’t work.

The Truth: Your air conditioning system cools at a consistent rate regardless of the temperature setting. Lowering the thermostat drastically won’t make your home cool faster—it just makes your system run longer, consuming more energy and increasing wear and tear.

What to Do Instead: Set your thermostat to an efficient temperature—around 78°F in summer and 68°F in winter. Consider installing a smart thermostat to optimize cooling and save on energy costs automatically.
