11 Common Myths vs HVAC Facts

Whether it’s the dog days of summer or a long winter’s night, you want to get the most out of your HVAC system all year long. Over the years, air conditioning myths and heating and cooling “tricks” and tips from less-than-reputable sources have infiltrated homes everywhere. Most of these tricks are ineffective at best, and sometimes even harmful.

HVAC is a hard niche to understand unless you’re heavily involved in it and know the system inside and out. That’s where we come in. These are some of the most common myths you’ve probably heard before, but A.A.S.M. Heating and Cooling has the truth you need to know.

The Truth Behind Common HVAC Myths

Myth #1: Air filters don’t need to be changed on a regular basis, so I can change it myself when needed…

The Truth: This one is only half false. Yes, you can change the air filter yourself, but they definitely need attention on a regular basis. The dirtier they get, the less efficiently they run.

Myth #2: Moving the thermostat all the way up or down cools or heats a building faster…

The Truth: Does an elevator come quicker if you push the button more than once? No, and the same concept applies to your thermostat. It isn’t a magic wand, and it doesn’t work harder or faster if you raise or lower it. The thermostat is nothing more than a regulator that instructs your system when to turn on and off based on the temperature you want the room to maintain.

Myth #3: Closing vents in rooms can save you more money…

The Truth: Actually, closing vents doesn’t save you money and can eventually cause problems in your system. When you close vents, it throws off your system’s balance and re-routes the airflow in your home. This potentially leads to other issues caused by pressure buildup in the ducts of your system.

Myth #4: Routine maintenance is not necessary…

The Truth: Routing maintenance for your HVAC system is the same as a standard oil change for your car. Not only is it necessary, but it’s critical when it comes to making sure your system works like it’s supposed to, regardless of the weather outside. While repairs aren’t always needed, routine maintenance ensures little problems don’t turn into big ones.

Myth #5: The bigger, the better…

The Truth: Bigger systems tend to cycle on and off more, which costs more and makes your system work harder, which in turn, shortens its lifespan. Some homeowners think a bigger system will work better, but sometimes working harder isn’t necessarily working smarter.

Myth #6: An energy efficient unit will reduce my bills…

The Truth: It could, but that’s not all that matters. Even the most energy efficient model won’t help reduce bills in a drafty house if the system isn’t being cared for properly. The truth is, you and your system both have to be efficient in the effort to lower utility bills.

Myth #7: Leaving the unit on is cheaper than turning it off…

The Truth: Many people believe that if you go out of town or are gone all day, it’s cheaper to set your thermostat high (or low depending on the season) rather than just turning it off. The truth is, having your unit cycle on/off doesn’t cost extra. It will always save more energy and money to just turn it off completely if you’re not using it.

Myth #8: If I’m hot, I’ll just use a fan…

The Truth: A fan is not an air conditioner. Fans are designed to circulate air, not to cool it. It can cool you off by moving air across your skin, but it will not actually lower the temperature of the room, even if you leave it on all day long.

Myth #9: My system doesn’t require maintenance…

The Truth: It doesn’t matter how fancy or how expensive your system is, it still needs regular maintenance. Even a Lexus needs an oil change. The healthiest of people still visit their doctor regularly for check-ups. Your HVAC system works the same way. Routine maintenance measures are more simple and more cost-efficient to conduct and carry out, rather than waiting for something to go wrong and fix it all at once.

Myth #10: Keeping the temperature the same is more efficient…

The Truth: Keeping the same temperature all day long can be a risky move resulting in sky-high energy bills. The goal is to use the least amount of energy possible. Less energy is used when the difference between the inside and outdoor temperature is small, so it is a good idea to set your home’s temperature as close to the outdoor temperature as possible when you’re not home. A programmable thermostat allows you to change the temperature to achieve the best balance between efficiency and comfort.

Myth #11: Thermostat location doesn’t matter…

The Truth: If your thermostat is in direct sunlight, or near a vent, it will probably shut down your system too early. The thermostat should be placed in an area that is easy to access, but not near a vent or window.

Your HVAC system is there to provide thermal comfort and acceptable indoor air quality. Get the most effective use and fewer breakdowns by caring for your system the same way you care for your cars, home furnishings, or even your own health. Regular check-ups and ongoing maintenance increase longevity and ensure your family will be comfortable all year long. To ensure your system is working its best, talk with a pro at A.A.S.M.
