Homeowners in Ottawa rely on their HVAC systems to keep them comfortable throughout the year. However, there are plenty of misconceptions about heating, ventilation, and air conditioning that can lead to costly mistakes. In this article, we’ll debunk some of the most common HVAC myths so you can make informed decisions about your home’s comfort.
Myth #1: Closing Vents in Unused Rooms Saves Energy
Reality: Many homeowners believe that shutting vents in unused rooms reduces energy consumption. In reality, modern HVAC systems are designed to balance airflow. Closing vents can increase pressure in the system, making the furnace or air conditioner work harder, which may lead to higher energy bills and unnecessary wear on the equipment.

Myth #2: The Bigger the HVAC Unit, the Better
Reality: While it might seem like a larger system would heat or cool your home more effectively, an oversized unit can cause short cycling—turning on and off frequently—which leads to inefficient operation, uneven temperatures, and premature wear. A properly sized unit based on your home’s square footage and insulation is key to efficiency and comfort. Check out our guide to choosing the right HVAC system.
Myth #3: You Only Need to Change Your Filter Once a Year
Reality: HVAC filters should typically be changed every 1 to 3 months, depending on factors like pet hair, dust, and seasonal pollen levels. A dirty filter restricts airflow, reduces system efficiency, and can lead to costly repairs. Find out how regular maintenance saves you money.
Myth #4: Ceiling Fans Lower Room Temperature
Reality: Ceiling fans don’t actually cool the air; they create a wind-chill effect that makes you feel cooler. This means you can raise your thermostat by a few degrees in the summer while staying comfortable, but leaving a fan running in an empty room wastes energy. Learn more about energy efficiency.
Myth #5: HVAC Maintenance Is Unnecessary If Everything Seems Fine
Reality: Just because your system is running doesn’t mean it’s operating efficiently. Regular maintenance helps prevent breakdowns, extends the lifespan of your unit, and ensures optimal energy efficiency. Skipping annual tune-ups can lead to higher energy bills and expensive emergency repairs. Check out our HVAC maintenance plans.
Myth #6: Cranking the Thermostat Up or Down Cools/Heats Faster
Reality: Your HVAC system works at a constant rate, meaning setting your thermostat to extreme temperatures won’t speed up heating or cooling—it only makes the unit run longer, using more energy. Instead, set the thermostat to your desired temperature and be patient.
Myth #7: Duct Cleaning Is a Scam
Reality: While some companies make exaggerated claims about duct cleaning, periodic cleaning can be beneficial, especially if you notice excessive dust, mold, or airflow issues. A professional assessment can determine whether your ducts need cleaning to improve indoor air quality. Learn more about indoor air quality.
Myth #8: It’s Cheaper to Leave the Thermostat at a Constant Temperature
Reality: Many people think keeping the thermostat steady all day saves energy. However, using a programmable or smart thermostat to adjust temperatures when you’re away or asleep can significantly reduce energy costs without sacrificing comfort. Explore smart thermostat options.
Myth #9: Space Heaters Are an Efficient Way to Heat Your Home
Reality: Space heaters can be useful for supplemental heat, but they’re not a cost-effective way to heat an entire home. They consume a lot of electricity and can pose a fire hazard if used improperly. A properly functioning furnace or heat pump is a far better long-term solution.

Myth #10: All HVAC Companies Provide the Same Level of Service
Reality: Not all HVAC contractors are created equal. Experience, certifications, customer reviews, and company policies vary widely.
