Do you find yourself avoiding HVAC maintenance because you think it’s hard to do? You may even believe some of the many common myths about regular HVAC maintenance and think there is no need for you or your company to take action. Do any of these sound familiar?

  • “I’m too busy for HVAC maintenance.”
  • “My system is new and can handle anything.”
  • “I’m only here in the cold months. Why should I care about HVAC?”
  • “My system is older, but it still works. I don’t have time for maintenance.”

Even though HVAC equipment and systems are more efficient than ever, many myths about how they work and need to be maintained persist. There is a great deal of misinformation on the web and old tales passed on from one generation to another. As a result, everyone has different opinions about proper HVAC maintenance and care. We’re here to help you put those old, unnecessary habits to rest by debunking some of the most popular HVAC myths.

Myth: Close the vents in empty rooms to save energy.

Fact: Closing vents can cause leaks at the vent seams by increasing air pressure in the ducts. Closing vents in rooms that are not occupied will not save any energy. If you are accustomed to closing vents, your system will take longer to heat or cool the room when it is eventually occupied again. Closing only registers can cause too much resistance and compressor burnout due to a lack of refrigerant flow.

Myth: The location of the thermostat does not affect heating and cooling.

Fact: Wrong. If your thermostat is too close to vents, radiators, or windows, it could cause the system to shut down prematurely or operate for too long. For the most accurate temperature control, mount the thermostat at least 8 inches above floor level on the inside wall of the living space.

Myth: Routine maintenance is unnecessary.

Fact: Your HVAC system is a sophisticated mechanical system that needs annual maintenance, just like your car, motorcycle, refrigerator, or washing machine. Regularly inspecting it can help you avoid serious issues in the future.

Myth: Because it takes more energy to heat a cold room than it does to merely maintain its temperature, keep your thermostat set to the same temperature throughout the day and night.

Fact: If this HVAC myth were accurate, programmable thermostats that change the temperature in your home throughout the day would be unnecessary. Warming up a cold house in the morning requires far less energy than maintaining a constant temperature throughout the day and night.

Here are some practical suggestions:

  • Purchase a programmable thermostat and educate yourself on how to use it.
  • When you are away from home or asleep, lowering the temperature by a couple of degrees can save you a lot of money on your heating and cooling bills.
  • When there’s a cold front, close your shades and drapes at night. Drapes and curtains assist in the insulation of your home.
  • During the day, open your blinds and drapes to let the sun’s natural heating rays inside your home. Ensure that your registers and vents are free of any blockages.
  • Set your thermostat at around 68 degrees Fahrenheit, and when you need air conditioning, put it to 78 degrees Fahrenheit. Set the temperature roughly 8 degrees forward or back when at home or asleep to save money on heating and cooling.

Myth: You can use duct tape to seal air duct leaks.

Fact: Sealing air ducts with duct tape is not a wise idea. It tends to peel and does not adhere well. The best technique to seal your air ducts is to use mastic sealant. Look for any exposed duct connections and clean them before putting any aluminum foil tape or mastic sealer.

Myth: You will save money and energy by switching to portable electric heaters.

Fact: Everything depends on the situation. Thankfully, we don’t have to worry about this issue much in Florida.

However, for those one-off periods and cold fronts, if you are confined to one location and have a space heater nearby, turn off your central heating to save money and energy. Unfortunately, most individuals use portable heaters while concurrently running their central heating system. If this is the case, you are merely increasing your home’s energy use.

Gas heating is, on average, far more efficient than electric heating. If you’re trying to save money and energy by using portable space heaters, ensure your central heating system is turned off while you’re doing so. When you leave the nearby area, remember to turn off the space heater.

Myth: The size of the HVAC system depends on the building’s square footage.

Fact: Not entirely. When choosing and installing a new heating or cooling system, there are numerous aspects to consider. You should consider square footage and windows, window orientation, air leakage, volume, existing ductwork, and insulation and ventilation levels. You’d probably end up with a more extensive system and more significant upfront expenditures and energy bills if you only used the square footage of the house.

Myth: Air leaks can be easily found through windows, doors, and other openings.

Fact: Not totally. While air leaks around doors and windows are simple to see, many other sections of the home, such as areas surrounding floors and ceilings, around chimneys, pipes, ductwork, and other hard-to-reach spots, may have serious insulation issues.

The best approach to discover all of your house’s energy inefficiencies is to hire an expert to conduct a home energy audit. They’ll be able to locate the places in your home where you should focus your energy efficiency upgrades utilizing a blower door test and other techniques. After analyzing your home and locating the worst energy losses, you may discover that you had no idea where your major energy leaks were.

Myth: Increasing energy efficiency doesn’t do anything for the house.

Fact: One of the most sought-after home amenities is energy efficiency upgrades. And there’s an increasing desire for energy-saving measures. Lowering your energy bills benefits you not only while you live there, but it’s also likely to be a big selling point whenever you decide to sell.

Myth: The best solution for a hot and muggy room is to put an air conditioning unit in it.

Fact: While purchasing a window air conditioner may be the simplest way to chill a room, your central HVAC system may have a more severe airflow problem. Ignoring the problem by installing an air conditioning unit in the window will almost always make it worse. The easiest method to treat any hot or cold patches in your home is to schedule professional HVAC maintenance and address the cause of the problem rather than draining even more energy with a new window air conditioner.

Investing time and energy in weatherization upgrades, such as insulation, duct sealing, and caulking around windows and doors is a terrific way to increase the comfort inside your house all year.
