Debunking HVAC Myths for AirTech Heating

Written by:


In the world of heating, ventilation, and air conditioning (HVAC), several myths and misconceptions persist. At AirTech Heating, we believe in providing our customers with accurate information to help them make informed decisions. In this blog post, we’ll debunk some common HVAC myths.

Myth 1: Closing vents in unused rooms saves energy.

This is a common misconception. Closing vents can actually put more strain on your HVAC system and increase energy consumption. When vents are closed, the air has fewer pathways to circulate, leading to increased pressure and potentially damaging your system.

Myth 2: Air conditioning is not necessary if you live in a cooler climate.

While it’s true that cooler climates don’t require as much air conditioning, it’s still essential for maintaining indoor comfort and air quality. Air conditioners not only cool the air but also remove excess moisture, which can prevent mold growth and improve indoor air quality.

Myth 3: Bigger HVAC units are always better.

  1. Proper sizing is crucial for HVAC systems.
  2. An oversized unit will cycle on and off more frequently, leading to inefficient operation and uneven temperatures.
  3. An undersized unit will struggle to maintain comfortable temperatures, causing excessive strain and energy consumption.

Myth 4: HVAC maintenance is unnecessary if the system seems to be working fine.

Regular maintenance is essential for prolonging the lifespan of your HVAC system and ensuring efficient operation. Neglecting maintenance can lead to costly repairs and premature system failure.


At AirTech Heating, we strive to provide our customers with accurate information and reliable HVAC services. By debunking these common myths, we hope to help you make informed decisions about your home’s heating and cooling needs. Remember, proper installation, maintenance, and sizing are crucial for efficient and cost-effective HVAC performance.
