Separating Fact from Fiction HVAC Myths


When it comes to heating, ventilation, and air conditioning (HVAC) systems, there are numerous myths and misconceptions that can lead homeowners astray. At HART HVAC, we understand the importance of reliable information, which is why we’ve decided to debunk some of the most common HVAC myths.

Myth #1: Bigger is Always Better

Some people believe that installing the largest HVAC system available will ensure maximum comfort and efficiency. However, this is a fallacy. An oversized system can lead to:

  • Increased energy consumption
  • Uneven temperature distribution
  • Frequent cycling on and off
  • Shortened equipment lifespan

The optimal solution is to have a certified HVAC professional perform a load calculation to determine the right-sized system for your home.

Myth #2: Closing Vents in Unused Rooms Saves Energy

Contrary to popular belief, closing vents in unused rooms can actually increase energy consumption and potentially damage your HVAC system. When vents are closed, it creates an imbalance in the system, forcing it to work harder and leading to increased strain on the components.

Myth #3: HVAC Maintenance is Unnecessary

Regular maintenance is crucial for ensuring the longevity, efficiency, and optimal performance of your HVAC system. Neglecting maintenance can result in:

  1. Higher energy bills
  2. Frequent breakdowns
  3. Shortened equipment lifespan
  4. Poor indoor air quality

At HART HVAC, we recommend scheduling annual tune-ups to keep your system running smoothly and prevent costly repairs down the line.


By debunking these common HVAC myths, we hope to provide you with reliable information to make informed decisions about your home’s heating and cooling needs. If you have any further questions or concerns, our team of experts at HART HVAC is always here to assist you.
