When it comes to heating and cooling your home, there’s a lot of misinformation floating around. And guess what? That misinformation is costing you money. Whether it’s outdated advice, marketing gimmicks, or just plain myths, these HVAC misconceptions can lead to higher bills, unnecessary AC repairs, and a system that doesn’t perform like it should.
Let’s break down the top 10 HVAC myths that are draining your wallet—and what you can do to save money instead.
Myth #1: You Only Need to Change Your Filter Once a Year
Wrong. If you wait that long, you’re basically forcing your HVAC system to work overtime. A dirty filter restricts airflow, making your system work harder and increasing energy costs. Depending on your home (pets, dust levels, usage), you should be changing your air filter every 1-3 months.
How This Costs You:
- Higher energy bills
- More frequent AC repairs
- Shortened lifespan of your unit
Pro Tip: Mark your calendar or set a phone reminder to swap out your filter regularly.
Myth #2: Cranking the Thermostat Will Heat or Cool Your Home Faster
Your HVAC system doesn’t work like pressing the gas pedal in a car. It heats or cools at the same rate, no matter how extreme you set the temperature. Setting your thermostat to 50°F won’t cool your home any faster—it just makes your system run longer, which wastes energy and increases wear and tear.
Smart Move: Set your thermostat to a comfortable level and be patient. A programmable thermostat can help maintain ideal temperatures efficiently.
Myth #3: Closing Vents in Unused Rooms Saves Energy
This one sounds logical, but it’s dead wrong. Your HVAC system is designed for balanced airflow. Closing vents increases pressure in the system, which can cause leaks, damage, and higher energy bills.
Instead: Keep vents open and invest in zoned HVAC systems for better control over different areas of your home.
Myth #4: Bigger HVAC Systems Are Always Better
Oversized HVAC units don’t cool or heat efficiently. They cycle on and off too frequently, causing uneven temperatures, excessive wear, and wasted energy.
Solution: Get a professional to size your system correctly. Olive Air and Heating provides expert consultations to ensure your HVAC system is the right fit for your home.
Myth #5: Maintenance Is Optional
Skipping HVAC maintenance is like never changing your car’s oil and expecting it to run perfectly forever. Regular tune-ups prevent expensive repairs, improve efficiency, and extend the life of your system.

Myth #6: You Should Run Your HVAC System Until It Dies
If your HVAC system is old and inefficient, running it into the ground costs more in the long run. New energy-efficient models use up to 50% less energy than older units.
When to Upgrade: If your unit is over 10-15 years old, replacing it could save you thousands in energy costs.
Myth #7: Ceiling Fans Lower the Room Temperature
Fans don’t lower temperature; they just move air. That makes you feel cooler, but if you leave fans running in empty rooms, you’re just wasting electricity.
Pro Tip: Turn fans off when you leave the room.
Myth #8: AC Repair Isn’t Necessary If It’s Still Running
A struggling AC unit that “kinda works” is costing you way more than you think. Small issues turn into expensive breakdowns if ignored.

Myth #9: The Location of Your Thermostat Doesn’t Matter
Placing your thermostat near heat sources (windows, lamps, kitchens) throws off temperature readings. This causes your system to run longer than necessary, increasing costs.
Fix: Keep your thermostat in a central location, away from direct sunlight or drafts.
Myth #10: All HVAC Companies Are the Same
Not true. An inexperienced or shady contractor can botch an installation, overcharge for repairs, or recommend unnecessary replacements.
