10 Common HVAC Myths Debunked: What You Need to Know.

Know The Facts

As a homeowner, you probably want to keep your furnace and air conditioner working well because they make your home cozy. But it's tough to figure out what's true and what's not with all the different ideas out there.

Don't worry! We're here to clear up some common misunderstandings about heating and cooling. This will help you keep your family comfy and your HVAC system running smoothly.


MYTH 1: You only have to change the filter once a year.


THE FACTS: Your HVAC filter plays a crucial role in the efficiency and longevity of your system. Many people think they only need to change it once a year, but this is not the case. A dirty filter can restrict airflow, making your system work harder and less efficiently. It’s recommended to change your filter every 1-3 months, depending on the type of filter and the level of use in your home. This simple maintenance task can improve air quality and reduce strain on your HVAC system.


MYTH 2: A denser air filter is always better.


THE FACTS: Here’s another case where it can actually make things worse. Take a standard one-inch air filter. To replace it with a denser HEPA filter might seem like a good idea, and it will catch more particles. But it’s also reducing airflow significantly, which hurts your system in numerous ways.

The other danger is that that same one-inch HEPA filter will clog up faster, which makes the problem of airflow even worse. Unless you’re very regimented about changing your filter, you’re going to lose years off of the life of your system due to the extra work it’s putting in to overcome the loss of proper airflow.


MYTH 3: The bigger the HVAC system, the better.


THE FACTS: It’s a common misconception that a bigger HVAC system will provide better heating and cooling. In reality, an oversized system can lead to short cycling, where the unit turns on and off frequently, wasting energy and causing unnecessary wear and tear. A system that is too large for your home will also struggle to remove humidity effectively. It’s important to have a properly sized HVAC system installed by a professional to ensure efficiency and comfort.


MYTH 4: Close the vents in empty rooms to increase energy efficiency.


THE FACTS: Some believe that closing vents in unused rooms will save energy by redirecting airflow to the rooms you use most. However, this can disrupt the balance of your HVAC system. Modern systems are designed to operate with a certain amount of airflow, and closing too many vents can lead to pressure imbalances and strain on the system. It’s best to keep all vents open and unobstructed for optimal performance.


MYTH 5: My thermostat’s location doesn’t affect heating and cooling.


THE FACTS: The placement of your thermostat can greatly impact the efficiency of your HVAC system. If it’s located in a drafty area, near heat sources, or in direct sunlight, it can give inaccurate readings and cause your system to run more than necessary. Ideally, the thermostat should be placed in a central location away from these influences to accurately reflect the temperature of your home.

MYTH 6: I don’t need routine maintenance.


THE FACTS: Routine maintenance is essential for keeping your HVAC system running efficiently and prolonging its lifespan. Most manufacturers require at least 1 maintenance per year to keep the parts warranty active. Skipping maintenance can lead to reduced efficiency, more frequent breakdowns, and higher energy bills. Professional maintenance services include cleaning, inspecting, and tuning up your system to ensure it’s working at its best. It’s recommended to schedule maintenance at least once a year, ideally before the start of each heating and cooling season.


MYTH 7: An energy-efficient unit will reduce my bill.


THE FACTS: While energy-efficient HVAC units are designed to consume less energy than older models, other factors contribute to your overall energy bill. Your home’s insulation, ductwork condition, thermostat settings, and usage habits all play a role in determining your energy costs. While upgrading to an energy-efficient unit is a great step, it’s important to also address these other factors to maximize savings.


MYTH 8: Cover the outdoor unit during winter.


THE FACTS: Many believe that covering the outdoor unit during winter protects it from the elements and prolongs its lifespan. However, this can do more harm than good. Covering the unit can trap moisture inside, leading to rust and corrosion. Additionally, it can provide a cozy shelter for pests seeking refuge from the cold. HVAC units are designed to withstand winter weather, so it’s best to leave them uncovered and ensure they have proper airflow.


MYTH 9: Duct tape is good for duct leaks.


THE FACTS: Duct tape is unfortunately named, because it should never be used to fix a leaking or damaged duct. Certain types of foil tape can be used for this purpose, but this is generally not a type of tape that homeowners commonly have on-hand.

Even worse is when duct tape is used to repair chimney flues, which can get very hot. The duct tape will melt, becoming a potential hazard in addition to doing nothing beneficial.


MYTH 10: HVAC systems only cool and heat your home.


THE FACTS: When it comes to HVAC systems, many believe that their only purpose is to cool and heat your home. However, this is not the case. HVAC systems also circulate air throughout your home, essential for maintaining a comfortable environment. By ensuring that your HVAC system is properly maintained, you can rest assured that your home will be comfortable all year long.

Hot and cold spots can develop when your home isn’t adequately circulated, making it difficult to relax or get comfortable. Also, stagnant air can lead to several health problems, such as respiratory issues and allergies.
