5 popular HVAC myths (and why they exist in the first place)

Your home relies on its air conditioner, heat pump, and furnace for year-round comfort. Yet, if you’re like most U.S. homeowners, you probably only have a basic understanding of how these systems work. This can lead to many common misunderstandings about HVAC systems that spread both online and through word-of-mouth, becoming pervasive and popular HVAC myths over time.

In this article and the accompanying infographic, we’ll not only review some of the biggest misconceptions about air conditioners and furnaces, but also explore how these myths came to be and what sources of information you should trust as a homeowner.

Why are there so many popular HVAC myths out there?

Our industry is filled with misinformation. This is most likely due to the fact that HVAC systems are both complex and essential: almost every American home has an air conditioner, heat pump, or furnace, but few homeowners actually understand how the systems work beyond the surface level of adjusting the thermostat. After all, the same thing is true for cars, and there’s an equally large amount of superstitions, half-truths, and myths out there about how to best care for a vehicle.

One common thread linking all of these myths together is that they all make some sense at face value. For example, turning off your air conditioner during the day to save energy seems right. With nearly everything else in your home, you can conserve energy by turning it off and not using it. This myth is pervasive because homeowners extend that logic to their HVAC systems, thinking that shutting down the system entirely is the right way to go.

Finally, at least some of these myths probably have their origins with an unscrupulous or untrustworthy HVAC company trying to make a quick buck. Unqualified technicians can also—often out of ignorance—spread misinformation. This is just one of the reasons you should always work with a locally trusted cooling and heating company with NATE-certified technicians, like Dufrene’s Heating & Cooling.

Other common HVAC myths

Beyond the five reviewed in the infographic below, there are several other persistent myths that just won’t go away:

An HVAC technician can size your home with just the square footage

While the physical size of your home is an important factor in what size of system you might need, it’s not the only factor. Everything from insulation to the number of windows can come into play. Never trust an HVAC technician who says they can quote you on a new air conditioner, heat pump, or furnace system without coming to your home to take measurements. At Dufrenes Heating & Cooling, we offer free in-home estimates on new systems for this exact reason.

You can run your fan instead of your air conditioner

A ceiling or floor fan can help cool you down, but it’s important to recognize that the fan is only cooling the temperature of your skin, not the temperature of the air inside your home. As soon as you leave the radius of the fan, it’ll hit you just how hot it is. We recommend using fans to supplement, not replace, cooling in the summer.
