Is Your Air Conditioner Undersized or Oversized? | Air Design Answers – Episode 23
Is your air conditioner running all day? Or does it turn on and off every few minutes?
Believe it or not, both could be signs of a problem.
In this episode of Air Design Answers, Chris Hamilton and Todd Baker from Air Design Services break down one of the biggest misconceptions in home comfort: bigger isn't always better.
You'll learn why an oversized air conditioner can leave your home feeling cold but damp, why a properly sized system may run continuously on the hottest summer days, and how humidity plays a huge role in your overall comfort.
Whether you're replacing an aging air conditioner, building a new home, or simply wondering if your current system is performing the way it should, this episode is packed with practical advice, real-world stories, and expert insights from over 40 years in the HVAC industry.
