Dispelling Common Misconceptions About Residential HVAC Systems


At Anderson Bros, we take pride in providing top-notch heating and cooling services to our valued customers. However, we’ve encountered numerous myths and misconceptions surrounding residential HVAC systems that can lead to inefficient use, unnecessary expenses, and even potential safety hazards. In this blog post, we aim to debunk some of the most common myths and offer factual information to help you make informed decisions.

Myth #1: Bigger is Always Better

Many homeowners believe that installing a larger HVAC system will ensure better cooling or heating performance. However, this is a misconception. An oversized system will frequently cycle on and off, leading to inefficient operation, uneven temperature distribution, and higher energy bills. The proper sizing of an HVAC system is crucial for optimal performance and energy efficiency.

Myth #2: Closing Vents in Unused Rooms Saves Energy

  • This myth is widely spread but inaccurate.
  • Closing vents can disrupt the system’s balance, causing it to work harder and potentially leading to equipment damage.
  • Instead, consider zoning systems or programmable thermostats to manage temperature in different areas of your home efficiently.

Myth #3: Replacing Air Filters is Unnecessary

Neglecting to replace air filters is a common mistake that can have severe consequences. Clogged air filters restrict airflow, causing the system to work harder and potentially leading to breakdowns or premature failure. Additionally, dirty filters can contribute to poor indoor air quality, exacerbating respiratory issues and allergies. Regular filter replacement is essential for maintaining a healthy and energy-efficient HVAC system.
