7 HVAC Myths That Can Cost Homeowners Time and Money

7 HVAC Myths That Can Cost Homeowners Time and Money

7 HVAC Myths That Can Cost Homeowners Time and Money

Homeowners in Southside, Gadsden, and Etowah County rely on their HVAC systems for year-round comfort, energy efficiency, and indoor air quality. Yet, misinformation about heating and cooling can lead to higher energy bills, premature equipment wear, and unnecessary repairs. At Childress Heating & Cooling, we’ve served our community for over 20 years, helping families separate HVAC fact from fiction to save money and maintain comfortable homes.

In this guide, we’ll debunk 7 common HVAC myths that could be costing you and provide practical advice for keeping your system running efficiently.

Myth 1: Closing Vents in Unused Rooms Saves Energy

Many homeowners believe that closing vents in unused rooms reduces energy consumption. The truth is more complex:

  • HVAC systems are designed for balanced airflow. Closing vents can increase pressure in ductwork, causing leaks and reduced efficiency.
  • Uneven airflow may force your system to work harder, raising energy bills.

Instead of closing vents, use dampers to slightly adjust airflow or consider zoning systems for more precise temperature control.

Myth 2: Setting the Thermostat Lower Cools Your Home Faster

Turning the thermostat to the lowest setting won’t cool your home any faster:

  • Your AC operates at a fixed speed and temperature. Setting it lower only keeps it running longer, increasing energy use.
  • Smart or programmable thermostats allow for efficient temperature adjustments without wasting energy.

Maintaining a steady temperature, like 74–76°F in summer, keeps your home comfortable and prevents system strain.

Myth 3: Bigger HVAC Systems Are Always Better

Bigger isn’t always better when it comes to heating and cooling:

  • An oversized system may cycle on and off frequently, causing uneven temperatures and higher energy bills.
  • Undersized systems struggle to keep up, leading to constant operation and wear.

A professional HVAC load calculation ensures the right system size for your home.

Myth 4: You Don’t Need Annual HVAC Maintenance

Skipping yearly inspections can be costly:

  • Dirt, dust, and worn parts reduce efficiency and increase the risk of breakdowns.
  • A professional tune-up helps catch small issues before they become major repairs.

Schedule maintenance at least once a year to keep your system operating safely and efficiently.

Myth 5: Air Filters Only Need Replacing When They Look Dirty

A clean filter is critical for performance and air quality, even if it looks okay:

  • Filters trap dust, pollen, and allergens that impact indoor air quality and system efficiency.
  • Check filters monthly during heavy use and replace them every 1–3 months depending on your system and pets.

Using high-quality filters reduces dust buildup, protects the system, and ensures your home remains healthy and comfortable.

Myth 6: Closing Your AC Off When Away Saves More Than Using a Programmable Thermostat

Turning off your HVAC system entirely may save energy, but it has drawbacks:

  • Extreme indoor temperatures make the system work harder to reach the desired temperature when you return.
  • A programmable or smart thermostat can efficiently adjust the temperature while you’re away, saving energy without overworking your system.

Even small adjustments using programmable thermostats result in long-term energy and cost savings.

Myth 7: DIY Repairs Are Always Safe and Cost-Effective

Attempting to fix complex HVAC issues on your own can lead to costly mistakes:

  • Incorrect repairs can damage your system or void warranties.
  • Professional technicians have the knowledge and tools to safely service your HVAC system.

Call Childress Heating & Cooling for any repairs to ensure safety, efficiency, and long-lasting performance.

How to Avoid Costly HVAC Mistakes

  • Schedule annual maintenance with a licensed HVAC technician.
  • Replace or clean air filters regularly.
  • Use programmable or smart thermostats for energy savings.
  • Ensure ducts are sealed and vents are unobstructed.
  • Never attempt complex repairs without professional guidance.

By addressing these myths and following expert advice, homeowners can reduce energy bills, improve comfort, and extend the life of their HVAC systems.

Frequently Asked Questions (FAQs)

Q1: How often should I schedule HVAC maintenance?
