by J&J on February 28, 2025

When Northeast Ohio's winter temperatures drop, a reliable furnace is essential for keeping your home cozy. However, misconceptions about heating systems can lead to higher energy bills, unnecessary repairs, and decreased efficiency.

At J&J Plumbing, Heating, Cooling & Electric, we're here to set the record straight on five common furnace myths - so you can keep your home warm without wasting energy or money.

Myth #1: Cranking Up the Thermostat Heats Your Home Faster

False! Many furnaces only operate at one speed. Setting the thermostat higher won't make your furnace heat faster - it just makes it run longer, using more energy than necessary.

Solution: Set your thermostat to a comfortable temperature and let it run efficiently. For even better savings, consider a programmable or smart thermostat.

Myth #2: Closing Vents in Unused Rooms Saves Money

False! Modern HVAC systems are designed for balanced airflow. Closing vents creates pressure imbalances, forcing your furnace to work harder and potentially damaging your system.

Solution: Keep vents open for consistent airflow and optimal efficiency. If you want better temperature control, ask us about zoning systems!

Myth #3: A Bigger Furnace Is Always Better

False! An oversized furnace cycles on and off too frequently, wearing down components and failing to heat your home evenly.

Solution: Proper furnace sizing is crucial for efficiency, comfort, and longevity. Our experts can help you choose the right-sized system for your home's needs.

Myth #4: You Only Need to Change Your Filter Once a Year

False! During Northeast Ohio's cold months, your furnace works harder, and filters clog faster. A dirty filter reduces airflow, making your system less efficient and increasing wear and tear.

Solution: Check your furnace filter monthly and replace it every 1-3 months to maintain efficiency and improve indoor air quality.

Myth #5: Maintenance Isn't Necessary for a Newer Furnace

False! Even new furnaces need regular tune-ups to catch small problems before they become expensive repairs. Plus, many warranties require annual maintenance to remain valid.

Solution: Schedule annual furnace maintenance with our certified HVAC technicians to extend the life of your system and keep it running smoothly.
