The Top 5 AC Myths

Last month on our blog, we discussed tips and tricks to help you save money on air conditioning costs this summer. However, for every AC hack that works there’s also a rumor that’s not so trustworthy, and it’s important to be able to distinguish between the two—both for the sake of your comfort and your wallet. Keep reading for the top 5 AC myths, courtesy of our experienced HVAC experts, and make sure to call Dial One Johnson Plumbing, Cooling & Heating for the quality air conditioning services you need.

The 5 Most Common Myths About Air Conditioning

  1. You Should Always Get the Biggest AC Unit Possible: When it comes to air conditioning, the rule that “bigger is always better” doesn’t apply. Instead, it all depends on the size of your AC unit in relation to your space. While bigger air conditioners are required to cool bigger spaces, you can waste a ton of power and significantly drive up your AC costs by installing an AC unit that is oversized for your home. AC units that are either too big or too small for your space also tend to cycle on and off more frequently, which means they are likely to have a lower lifespan. Bottom line: think of your air conditioner the same way you would think of a car engine. You need enough power to get you where you’re going, but not so much that you end up causing a crash in the process.
  2. A Lower Thermostat Setting Means A Cooler Home: As we discussed on our blog last month, it is actually better to turn your thermostat up during the summertime, rather than down. This may seem counterintuitive, but while your air conditioner will not function more effectively or have to work less hard with a lower thermostat setting, your overall energy costs will rise if you crank your thermostat temperature too low. Because your thermostat setting does not directly affect your AC’s performance, it’s better just to offset your energy costs by turning it up during peak air conditioning months.
  3. Thermostat Placement Has No Effect on Temperatures: While a lot of homeowners are unaware of this, you may be able to increase energy efficiency by installing a thermostat on an interior wall and out of direct sunlight. According to the U.S. Department of Energy, a thermostat that is not only easy to access but unobstructed and away from doors, windows, and air pockets will function more efficiently, ensuring you consistently achieve the desired temperature in your home. So, to summarize—turning your thermostat down during the summer: unnecessary. Making sure your thermostat is in a protected area: better for AC performance and overall comfort (this rule may vary depending on whether your home is equipped with a smart thermostat.)
  4. Your AC Unit Does Dot Affect Humidity: As the name suggests, your air conditioner isn’t just for cooling your air—it’s also for conditioning it. This is why an effective AC system will also remove humidity from your air, ensuring you not only feel cooler but that humidity levels are reduced throughout your home as well.
  5. You Should Close Vents When You Are Out of the Room: A lot of people think that it is best to close the air vents in rooms they do not use as much. But although you might assume that cooling rooms you do not use as much would be a waste of air, the opposite is actually true. Closing off your vents simply makes it harder for your air conditioner to distribute air evenly throughout your house, thus potentially making your system work harder and costing you more money. In short, closing vents to cut off air from a given room does not save money, it simply cools your air ducts rather than that room.
