Don’t let fiction compromise your comfort, wallet, or indoor air quality.
When it comes to your heating and air system, misinformation can be more than a nuisance—it can lead to poor decisions, high electricity bills, and even long-term damage to your HVAC equipment. At Roots Heating & Air, we believe knowledge is power, and we’re here to debunk some of the most persistent myths that homeowners still believe about their air conditioning and heating systems.
Myth #1: “Turning off the AC when I leave wastes energy.”
Truth: Leaving your air conditioner on while you’re out is one of the fastest ways to waste electricity. A programmable thermostat or smart thermostat allows you to regulate room temperature based on your schedule, maintaining efficiency and reducing energy consumption. With these tools, your HVAC system can cool or heat only when it’s needed—maximizing comfort and minimizing cost.
Myth #2: “You only need to change your air filter once a year.”
Truth: Your air filter plays a critical role in removing dust, particulates, and allergens from your home’s airflow. Ignoring it for too long leads to reduced indoor air quality, blocked air handlers, and excess strain on your cooling system. Most filters should be replaced every 30–90 days, especially if you have pets, allergies, or live in a high pollen or dust zone.
Myth #3: “The bigger the HVAC system, the better.”
Truth: Oversizing your HVAC unit leads to inefficient short cycles, poor humidity control, and faster wear and tear on your compressor, evaporator, and refrigerant lines. An efficient HVAC system is not about size—it’s about balance. Proper system sizing, based on square footage, insulation, and window placement, improves HVAC efficiency and extends the system’s longevity.
Myth #4: “Close vents in unused rooms to save money.”
Truth: Closing vents disrupts your ventilation system’s pressure balance, potentially causing duct leaks and reduced airflow. Your furnace, heat pump, or air conditioning system may end up working harder to maintain temperature, increasing wear and raising your utility bills.
Myth #5: “Thermostat placement doesn’t matter.”
Truth: Where you install your thermostat affects how your system performs. A poorly placed device—too close to windows, in direct sunlight, or near the roof or attic—can misread temperatures. For the best performance, install your thermostat on an interior wall, away from direct heat or drafts.
Myth #6: “Routine HVAC maintenance is optional.”
Truth: Skipping regular HVAC services shortens the lifespan of your system and reduces efficiency. Maintenance checks catch small issues like refrigerant leaks, dirty air filters, or worn plumbing components before they cause major breakdowns. Whether it’s your heat pumps, boiler, or air handler, consistent care reduces repair costs and improves HVAC unit performance.
Myth #7: “An energy-efficient unit will always lower my bills.”
Truth: While newer home appliances like high-SEER air conditioners or ENERGY STAR-rated heat pumps are more efficient, they must work in a well-maintained home to perform as expected. Sealing windows, insulating the ceiling and attic, and checking ductwork for leaks with something better than duct tape are essential to reduce electricity consumption and improve climate control.
Myth #8: “Covering the outdoor unit protects it in winter.”
Truth: For systems like heat pumps that operate year-round, covering the outdoor unit can trap water and debris, increasing the risk of mildew and corrosion. If necessary, place a board over the top during heavy snow, but avoid full enclosures that block airflow and trap moisture.
Bonus Truth: HVAC Systems Affect More Than Comfort
Neglecting your HVAC system doesn’t just impact your wallet—it affects your health. Poor indoor air quality can worsen allergy symptoms, aggravate respiratory conditions, and distribute dust, particulates, and even bacteria throughout your home. Adding humidifiers or air purifiers, replacing air filters, and scheduling regular duct cleaning improve your home’s overall air quality.
Also, don’t underestimate the benefit of running a ceiling fan or using smart technology to automate your air conditioning system. Every little change can support an efficient HVAC system and help you save money in the long run.
