Debunking Common Myths About Air Conditioning


When it comes to air conditioning systems, there are many myths and misconceptions that have been circulating for years. At Harley’s Heating & Air, we understand the importance of providing accurate information to our customers. In this blog post, we will debunk some of the most common myths about air conditioning.

Myth #1: Closing Vents Saves Energy

Many people believe that closing vents in unused rooms can save energy and lower their utility bills. However, this is a myth. Air conditioning systems are designed to work efficiently when all vents are open and the airflow is balanced throughout the home. Closing vents can actually increase energy consumption and strain the system.

Myth #2: Bigger is Better

Some homeowners think that installing a larger air conditioning unit will provide better cooling. This is not necessarily true. An oversized unit will cycle on and off more frequently, leading to uneven temperatures and increased energy consumption. It’s essential to have a professional AC contractor in Lincoln, NE, properly size the unit based on the square footage of your home and other factors.

Myth #3: Leaving the AC Running All Day Saves Energy

Another common myth is that leaving the air conditioner running all day while you’re away from home saves energy. The truth is, an air conditioning system works harder to cool an empty house than one that is occupied. It’s more efficient to turn off the AC or set it to a higher temperature when you’re not home, and then adjust it to a comfortable level when you return.

Myth #4: Air Conditioning is Bad for Your Health

Some people believe that air conditioning can cause respiratory issues, headaches, and other health problems. While it’s true that poorly maintained systems can circulate dust and allergens, modern air conditioning units are designed to improve indoor air quality when properly serviced and maintained.
