When it comes to heating and cooling your home, there’s a lot of misinformation floating around. Many homeowners believe they are making energy-efficient choices when, in reality, they may be costing themselves more in the long run. At KL Mechanical, we provide expert HVAC services in the Comox Valley, and we’re here to set the record straight on some of the most common HVAC myths.
Myth: Turning Off Your AC When You Leave the House Is a Waste of Energy
Fact: It’s a common misconception that leaving your AC set at a higher temperature is the best way to save energy. The truth is, shutting it off when you’re not home will always reduce energy use. If you want to manage your home’s temperature efficiently, consider a programmable thermostat. This allows you to schedule temperature adjustments so your home is cool when you return without running the system all day.
Myth: You Only Need to Change Your Air Filter Once a Year
Fact: Your HVAC system relies on clean airflow to function properly. A dirty air filter can clog the system, reducing airflow and forcing your unit to work harder. For optimal performance, change or clean your air filter every three months—or more often if you have pets or allergies.
Myth: The Bigger the HVAC System, the Better
Fact: An oversized HVAC system will cycle on and off more frequently, leading to inefficient performance, increased wear and tear, and higher energy bills. The best approach is to size your system to fit your home’s unique heating and cooling requirements. A professional HVAC technician can help you determine the right size for maximum efficiency and comfort.
Myth: Closing Vents in Unused Rooms Increases Energy Efficiency
Fact: It may seem logical to close vents in empty rooms, but this actually disrupts your HVAC system’s airflow balance. This can lead to increased pressure in the system, forcing it to work harder and potentially causing damage over time. Instead of closing vents, use zoning solutions or smart thermostats to optimize temperature control in different areas of your home.
Myth: My Thermostat’s Location Doesn’t Matter
Fact: Where you place your thermostat has a big impact on your HVAC system’s efficiency. If it’s too close to vents, windows, or radiators, it may misread the temperature, causing your system to turn on or off unnecessarily. Ideally, thermostats should be installed in a central location away from direct heat sources or drafts.
Myth: Routine Maintenance Isn’t Necessary
Fact: Just like your car needs regular tune-ups, your HVAC system requires annual maintenance to keep it running smoothly. Routine inspections can help identify minor issues before they become costly problems, ensuring your system operates efficiently and prolonging its lifespan.
Myth: An Energy-Efficient Unit Will Automatically Lower My Energy Bills
Fact: Upgrading to an energy-efficient unit is a great step, but other factors—such as poor insulation and leaky windows—can still drive up energy costs. To maximize efficiency, consider improving your home’s insulation and sealing air leaks. A whole-home approach will provide the best energy savings.
Myth: You Should Cover Your Outdoor Unit During Winter
Fact: If you have a heat pump, it operates year-round and should never be covered. Even for traditional AC units, covering them can trap moisture inside, leading to corrosion and damage. Instead, keep the area around the unit clear of debris to maintain proper airflow.
