Dispelling Air Conditioning Myths for Optimal Comfort


When it comes to air conditioning, myths and misconceptions can spread like wildfire, leading to inefficient cooling practices and increased energy costs. At Hartwick Heating & AC, we’re dedicated to providing our customers with accurate information and debunking these common myths. In this blog post, we’ll tackle some of the most prevalent myths surrounding A/C installation, service, and repair.

Myth #1: Bigger is Always Better

One widespread myth is that a larger air conditioning unit will cool your home more effectively. However, this couldn’t be further from the truth. An oversized unit will cool your space too quickly, leading to frequent cycling on and off, increased energy consumption, and uneven cooling. The key is to have a properly sized system that matches your home’s specific cooling needs.

Myth #2: Closing Vents in Unused Rooms Saves Energy

  • Many homeowners believe that closing vents in unused rooms can save energy, but this practice can actually do more harm than good.
  • Closing vents disrupts the system’s designed airflow, causing the A/C to work harder and potentially leading to equipment damage.
  • Instead, keep vents open and consider zoning systems or smart thermostats to better control individual room temperatures.

Myth #3: Air Conditioning Causes Illness

Some people believe that air conditioning can cause illnesses like colds or flu. However, this is simply not true. Air conditioning units do not create or spread viruses; they simply circulate the air in your home. Proper maintenance and clean filters are essential for ensuring good indoor air quality.
