As a homeowner, you may find yourself trying to keep your air conditioner top-notch, as it serves an essential role in keeping your home comfortable. However, with so many varying opinions and sources, it can be hard to separate fact from fiction. Don’t sweat it. We’re busting some of the most common heating and cooling myths to help keep your family comfortable — and keep your HVAC system in good working order.
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: 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 3: 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 4: 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 5: 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 6: An energy-efficient unit will automatically 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 7: 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.
