5 Popular Myths About HVAC Systems

Understanding your HVAC system can sometimes feel like navigating through a maze of myths and misconceptions. At Precision Air, we believe that knowledge is power, so we thought we’d start by taking a look at where these ideas come from and why they’re misinformed. Let’s debunk five of the most popular HVAC myths and set the record straight with the facts.

In this article, we’ll bust the following five popular HVAC myths:

  • Myth: The Bigger the HVAC System, the Better It Works
  • Myth: If the HVAC System Isn’t Broken, Don’t Fix It
  • Myth: Duct Tape Is Good for HVAC Duct Leaks
  • Myth: Square Footage Determines HVAC Sizing
  • Myth: A New HVAC System Will Drastically Increase Home Value

Myth #1: The Bigger the HVAC System, the Better It Works

There’s a common belief that a larger HVAC system will provide better performance. This myth likely stems from the assumption that more power equals more efficiency and comfort.

The Facts:

Contrary to popular belief, when it comes to HVAC systems, bigger isn’t always better. Oversized systems can lead to short-cycling, where the system turns on and off more frequently than necessary. This not only causes wear and tear but also inefficiency. The key is to have a system properly sized for your space, ensuring it operates efficiently and effectively.

Myth #2: If the HVAC System Isn’t Broken, Don’t Fix It

Many people think that if their HVAC system is running, it doesn’t need maintenance. This idea comes from the notion that you only fix things when they stop working.

The Facts:

Waiting for your HVAC system to break down before servicing it is like waiting for your car to stop running before getting an oil change. Regular maintenance is essential for efficiency, comfort, and longevity of your system. Proactive maintenance helps catch minor issues before they turn into major (and costly) problems.

Myth #3: Duct Tape Is Good for Duct Leaks

It’s a common assumption and misconception that duct tape, named after ducts, is suitable for fixing leaks in HVAC ductwork.

The Facts:

Despite its name, duct tape is not the solution for fixing leaking or damaged ducts. In fact, using duct tape for such repairs can lead to more harm than good. Specialized foil tapes are better suited for sealing ducts and ensuring they remain airtight and efficient.

Myth #4: Square Footage Determines HVAC Sizing

Many believe that the size of an HVAC system can be determined solely based on the square footage of a building or home. This simplification overlooks many other critical factors.

The Facts:

There’s a lot that goes into determining the right size for an HVAC system, and square footage is just one small piece of the puzzle. Aspects like window quality, insulation, ceiling height, and overall home layout play crucial roles in system sizing. Accurate estimation requires considering all these elements, not just square footage.

Myth #5: A New HVAC System Will Drastically Increase Home Value

Some homeowners think that installing a new HVAC system will significantly boost their home’s market value.

The Facts:

While a new HVAC system can be a selling point, it doesn’t always significantly increase home value. Home inspectors often focus on the age and brand of the system rather than its sophistication. A new system can remove potential negotiation obstacles, but it’s not a guaranteed value booster.

By understanding the truths behind these myths, homeowners and business owners can make more informed decisions about their HVAC systems. At Precision Air, we’re committed to providing accurate information and high-quality services for your heating and cooling needs.
