Debunking HVAC Misconceptions


When it comes to heating and cooling systems, there are numerous myths and misconceptions that circulate. At Childs Heating & Air, we strive to provide accurate information to our customers. In this blog post, we’ll address some common myths and shed light on the truth behind them.

Myth #1: Closing vents saves energy

Many people believe that closing vents in unused rooms can save energy. However, this is a misconception. Your HVAC system is designed to work efficiently when all vents are open. Closing vents can actually increase the pressure in your ductwork, causing your system to work harder and use more energy.

Myth #2: Bigger is always better for AC units

While it’s important to have an appropriately sized air conditioner for your home, bigger isn’t necessarily better. An oversized unit will cycle on and off more frequently, leading to inefficient operation and potential moisture issues. A professional HVAC technician can assess your home’s cooling needs and recommend the right-sized unit.

Myth #3: Changing air filters is unnecessary

Regularly changing your air filters is crucial for maintaining indoor air quality and ensuring your HVAC system runs efficiently. Clogged air filters restrict airflow, causing your system to work harder and potentially leading to breakdowns or premature failure.

Myth #4: HVAC maintenance is optional

  • Regular maintenance is essential for prolonging the life of your HVAC system.
  • It helps identify and address potential issues before they become major problems.
  • Neglecting maintenance can lead to higher energy bills, reduced efficiency, and costly repairs.


At Childs Heating & Air, we prioritize educating our customers and dispelling common myths about HVAC systems. By understanding the truth behind these misconceptions, you can make informed decisions and ensure your heating and cooling systems operate efficiently and effectively.
