The Truth About HVAC Maintenance Myths


When it comes to heating, ventilation, and air conditioning (HVAC systems), there are numerous myths that can lead homeowners astray. At Gustafson Heating & Air Conditioning, we’re committed to debunking these myths and providing our customers with accurate information to ensure their HVAC systems operate efficiently and effectively.

Myth #1: Closing Vents Saves Energy

One common misconception is that closing vents in unused rooms can save energy. However, this is not true. When you close vents, it increases the pressure in your ductwork, causing your HVAC system to work harder and potentially leading to leaks or damage.

Myth #2: Bigger is Always Better

Many homeowners believe that a larger HVAC unit will provide better cooling and heating. However, this is not the case. An oversized unit will cycle on and off more frequently, leading to inefficient operation and increased energy costs.

Busting the Myths

  1. Regular Maintenance is Essential: Contrary to popular belief, regular maintenance is crucial for the optimal performance and longevity of your HVAC system. Professional technicians can identify potential issues early and ensure your system operates at peak efficiency.
  2. HVAC Systems Require Proper Sizing: To ensure maximum efficiency and comfort, your HVAC system must be properly sized for your home’s square footage and insulation levels. A professional load calculation is necessary to determine the right size.
  3. Air Filters Should be Changed Regularly: Neglecting to change your air filters can lead to decreased indoor air quality and system inefficiency. Follow the manufacturer’s recommendations for filter replacement.


At Gustafson Heating & Air Conditioning, we prioritize educating our customers and providing accurate information. By debunking these common HVAC myths, we hope to empower homeowners to make informed decisions about their heating and cooling systems, ensuring optimal performance, energy efficiency, and indoor comfort.
