Dispelling HVAC Myths for Optimal Comfort


In the realm of heating and cooling systems, various myths and misconceptions have circulated over the years. At Cheshire Heating & Air, we believe in providing our customers with accurate information to ensure their homes remain comfortable and energy-efficient. In this blog post, we’ll debunk some common HVAC myths and shed light on the truth.

Myth #1: Closing Vents Saves Energy

Many homeowners believe that closing vents in unused rooms can help conserve energy and reduce utility bills. However, this practice can actually do more harm than good. HVAC systems are designed to operate with a balanced airflow, and closing vents disrupts this balance, causing the system to work harder and potentially leading to premature wear and tear.

Myth #2: Bigger is Better for HVAC Systems

It’s a common misconception that larger HVAC systems automatically translate to better performance. In reality, an oversized system can lead to inefficient operation, increased energy consumption, and potential moisture issues. A professional HVAC technician should properly size the system based on the specific requirements of your home.

Myth #3: Air Filters Only Need Changing Once a Year

  • Air filters play a crucial role in maintaining indoor air quality and system efficiency.
  • Neglecting to change them regularly can lead to reduced airflow, increased energy consumption, and potential system breakdowns.
  • The recommended frequency for changing air filters varies based on factors such as filter type, household occupancy, and the presence of pets.

Myth #4: HVAC Maintenance is Unnecessary

Regular maintenance performed by a professional HVAC technician is essential for ensuring optimal system performance, energy efficiency, and longevity. During maintenance visits, technicians can identify and address potential issues before they escalate into costly repairs.


At Cheshire Heating & Air, we strive to provide our customers with accurate information and exceptional service. By debunking these common HVAC myths, we hope to empower homeowners to make informed decisions about their heating and cooling systems. Remember, proper system maintenance, sizing, and airflow are crucial for achieving optimal comfort and energy efficiency in your home.
