Debunking HVAC Myths for Optimal Comfort


At Alan Energy Services, we understand the importance of reliable HVAC services in Elmhurst, IL, and the surrounding areas. As a leading provider of exceptional HVAC solutions, we aim to dispel common myths and misconceptions that often surround this vital industry. In this blog post, we’ll debunk some prevalent myths to help you make informed decisions about your home’s heating, ventilation, and air conditioning systems.

Myth #1: Bigger is Always Better

One widespread myth is that larger HVAC units are inherently better at cooling or heating your home. However, this is not necessarily true. An oversized unit may cycle on and off more frequently, leading to inconsistent temperatures and higher energy bills. The key is to have a properly sized system that matches the square footage and insulation levels of your home.

Myth #2: Closing Vents Saves Energy

  • Many homeowners believe that closing vents in unused rooms can save energy, but this is a misconception.
  • Closing vents can actually increase the strain on your HVAC system, leading to inefficient operation and potential breakdowns.
  • It’s better to keep all vents open and adjust the thermostat to your desired temperature.

Myth #3: Air Filters Don’t Need Regular Replacement

Neglecting to replace air filters is a common mistake that can have severe consequences for your HVAC system and indoor air quality. Clogged filters restrict airflow, causing your system to work harder and consume more energy. Regular filter replacements (typically every 1-3 months) can improve efficiency, prolong the lifespan of your equipment, and ensure healthier indoor air.
