Busting HVAC Myths Promoted by Misinformation



In the world of HVAC services, myths and misconceptions often circulate, leading to confusion and potentially costly mistakes. At Sigma-Tremblay, we believe in empowering our customers with accurate information to make informed decisions about their heating, ventilation, and air conditioning systems. In this blog post, we’ll debunk some common myths and set the record straight.

Myth #1: Closing vents in unused rooms saves energy.

Many people believe that closing vents in unused rooms can reduce energy consumption by preventing heated or cooled air from entering those spaces. However, this practice can actually increase your energy bills and strain your HVAC system.

When you close vents, it disrupts the carefully designed airflow and pressure balance within your HVAC system. This can lead to increased energy consumption as the system works harder to compensate for the restricted airflow. Additionally, it can cause uneven temperatures throughout your home and potentially damage your HVAC components.

Myth #2: Bigger is always better when it comes to HVAC units.

It’s a common misconception that larger HVAC units are more efficient and effective. The truth is, an oversized unit can actually waste energy and fail to properly regulate indoor temperatures.

  1. Oversized units cycle on and off more frequently, leading to increased energy consumption and wear and tear on the system.
  2. They are less effective at dehumidifying the air, resulting in a clammy indoor environment.
  3. Oversized units may not run long enough to evenly distribute conditioned air throughout your home.

It’s crucial to have a professional HVAC technician properly size your system based on factors such as your home’s square footage, insulation levels, and climate conditions.

Myth #3: HVAC maintenance is unnecessary if the system appears to be working fine.

Many homeowners neglect regular HVAC maintenance, believing that their system is running smoothly and doesn’t require servicing. However, this approach can lead to costly breakdowns and reduced efficiency.

Regular maintenance by a professional HVAC technician can:

  • Identify and address minor issues before they become major problems
  • Ensure optimal energy efficiency and prolong the lifespan of your HVAC system
  • Improve indoor air quality by cleaning and replacing air filters
  • Identify potential safety hazards and prevent accidents

Neglecting routine maintenance can ultimately cost you more in the long run due to higher energy bills, unexpected repairs, and premature system replacements.
