Debunking Common HVAC Myths
There’s a lot of information about the best way to care for your home’s HVAC system. Many homeowners believe common HVAC myths. These myths can hurt system performance, cause unnecessary repairs, and raise energy bills.
Myth #1: Bigger HVAC Units Are Always Better
One of the most common HVAC problems is installing an oversized unit. This leads to short cycling, higher energy use, and faster system wear.
Service Express Tip: Proper HVAC sizing is essential. An HVAC professional can calculate the right system size based on your home’s layout, square footage, and insulation.
Myth #2: You Only Need to Change Your Filter Once a Year
Many people believe that filters only need to be changed once a year, but this is one of the most common HVAC myths. You should check your filters every month and replace them every one to three months.
Service Express Tip: Changing your filters often can improve indoor air quality and reduce stress on your HVAC system. This helps prevent common problems like clogged systems and poor airflow.
Myth #3: Closing Vents in Unused Rooms Saves Money
While closing vents might seem like a good way to save energy, it can do more harm than good. Closing vents disrupts airflow, increases duct pressure, and strains your system, leading to reduced efficiency or damage.
Service Express Tip: Instead of closing vents, consider getting a zoned HVAC system or a programmable thermostat. These options help you control the temperature in different areas of your home.
Myth #4: Maintenance Isn’t Necessary Until Something Breaks
Waiting until your HVAC system malfunctions to schedule maintenance is a mistake that can cost you time and money. Tune-ups and inspections are essential to avoid common problems, such as refrigerant leaks, dirty coils, and clogged filters.
Service Express Tip: Schedule maintenance for your air conditioning in the spring and your heating in the fall. This helps catch problems early and avoid extensive repairs.
Myth #5: Cranking the Thermostat Makes it Heat or Cool Faster
Homeowners often believe the old air conditioning myth that cranking the thermostat will cool or heat a room faster. HVAC systems operate at a consistent speed. Adjusting the thermostat higher or lower will not speed up the process but will waste energy.
Service Express Tip: Set your thermostat to the desired temperature and be patient. Consider upgrading to a smart thermostat that automatically adjusts according to your schedule.
Myth #6: HVAC Systems Don’t Impact Indoor Air Quality
Poorly maintained systems can lead to the buildup of dust, allergens, and other pollutants. Without proper filtration, your HVAC system may circulate these contaminants throughout your home.
Service Express Tip: Consider installing an air purification system, UV lights, or scheduling a duct cleaning service. Regularly replacing filters also helps maintain a healthier living environment.
New Myth #7: Ceiling Fans Lower the Temperature in a Room
Ceiling fans don’t lower the air temperature. They merely circulate air, which can help make you feel cooler. However, fans don’t reduce the actual temperature of the room.
Service Express Tip: Use fans in combination with your HVAC system to circulate the cooled or heated air. Turn your ceiling fans off when you leave a room to save energy.
Myth #8: You Can Save Money with DIY HVAC Repairs
Attempting HVAC repairs on your own is one of the biggest mistakes homeowners can make. DIY repairs can cause more damage, void warranties, and even create safety hazards.
Service Express Tip: Always call certified HVAC professionals for repairs and maintenance, especially when dealing with refrigerant or electrical components.
Myth #9: You Can Install a Thermostat Anywhere
Putting thermostats in the sun, near heat-producing appliances, or in drafty areas can cause inaccurate temperature readings. This can affect comfort and increase energy bills.
Service Express Tip: Choose a central location for your thermostat. Having your thermostat professionally installed will ensure it is positioned correctly for maximum efficiency.
Myth #10: Turning Off Your HVAC System When You're Not Home Saves Energy
One of the most common HVAC misconceptions is that turning your system off completely when you leave home will save energy. This forces your HVAC system to work harder when you return to bring your home back to the desired temperature.
Service Express Tip: Instead of turning the system off, set your thermostat to an energy-saving mode while you’re away. Consider investing in a smart thermostat that automatically adjusts the temperature based on your schedule.
