Believing these myths can lead to unnecessary expenses, reduced comfort, and even damage to your system. Let’s set the record straight by debunking 10 common HVAC myths!
Myth 1: You Only Need to Change Your Filter Once a Year.
Many homeowners believe they only need to change their HVAC filters once a year. However, filters should be checked and replaced every 1-3 months, depending on your usage, the type of filter, and whether you have pets or allergies. A dirty filter can reduce airflow, making your system work harder and increasing your energy bills.
Myth 2: Bigger HVAC Systems Are Always Better.
It’s a common misconception that a bigger HVAC system will provide better heating or cooling. In reality, an oversized system can cause short cycling, where the system turns on and off too frequently. This not only reduces efficiency but also wears out the system faster. The right-sized unit, properly installed, will provide the best performance and comfort.
Myth 3: Closing Vents in Unused Rooms Saves Money.
Closing vents in unused rooms seems like a good way to save energy, but it can actually damage your HVAC system. Modern systems are designed to heat and cool entire homes, and closing vents can create pressure imbalances, reduce efficiency, and increase wear and tear on your unit.
Myth 4: You Don’t Need Annual Maintenance.
Some people believe that if their HVAC system seems to be working fine, they can skip annual maintenance. Regular maintenance is crucial for identifying potential problems early, improving efficiency, and prolonging the system’s lifespan. Skipping maintenance can lead to unexpected breakdowns and costly repairs.
Myth 5: Thermostats Should Be Left at One Temperature All Day.
Many think that keeping the thermostat at a constant temperature all day is the most energy-efficient option. However, adjusting the thermostat by a few degrees when you’re not home or during sleep can save on energy costs. A programmable or smart thermostat can make these adjustments automatically.
Myth 6: Turning Your System Off When You Leave Saves Energy.
Turning off your HVAC system completely when leaving the house might seem like a smart move, but it can actually cause more energy usage when you return and turn it back on. Instead, set your thermostat a few degrees higher (in summer) or lower (in winter) to save energy without overworking the system when you come back.
Myth 7: Duct Tape Is the Best Fix for Leaky Ducts.
Despite its name, duct tape is not ideal for sealing ducts. It tends to degrade over time due to temperature fluctuations. A better option is to use duct mastic or specialized foil tape for a more durable and effective seal.
Myth 8: All HVAC Filters Are the Same.
Not all HVAC filters are created equal. Different filters have different MERV (Minimum Efficiency Reporting Value) ratings that determine their effectiveness at capturing particles. A higher MERV rating means better filtration, which is especially important for households with allergies or respiratory issues.
Myth 9: You Can Install Your Own HVAC System to Save Money.
While some homeowners may consider installing their own HVAC systems to save money, this can lead to improper installation, reduced efficiency, and voided warranties. Professional installation ensures the system is correctly sized, balanced, and safely installed, maximizing efficiency and performance.
Myth 10: Air Conditioning Units Only Need Refrigerant When They Are Low.
HVAC systems are designed to operate with a specific amount of refrigerant. If your system needs refrigerant, it usually means there’s a leak that needs professional attention. Simply refilling refrigerant without fixing the leak can lead to ongoing issues and additional costs.
