1. MYTH: You Only Need to Change Your Filter Once a Year Reality: Your filter should typically be changed every 1–3 months. Dirty filters restrict airflow, reduce efficiency, and strain your HVAC system. If you have pets, allergies, or a busy household, you may need to change it more often. A clean filter helps your system run smoother, keeps your indoor air cleaner, and can lower energy bills. 2. MYTH: Closing Vents in Unused Rooms Saves Energy Reality: This can actually increase your energy usage and damage your HVAC system. HVAC systems are designed for balanced airflow. Closing vents throws off that balance, increasing pressure in the ducts and forcing your system to work harder. This can lead to leaks, inefficient performance, and higher energy costs. 3. MYTH: Bigger HVAC Systems Are Always Better Reality: Oversized systems cycle on and off more frequently, wasting energy and wearing out faster. An HVAC system should be properly sized for your home. Too large, and it won’t run long enough to remove humidity; too small, and it can’t keep up. Either way, comfort and efficiency suffer. A professional load calculation ensures the right fit. 4. MYTH: You Don’t Need Annual Maintenance if Your System Is Working Fine Reality: Skipping maintenance is like skipping oil changes—eventually, it’ll catch up with you. Preventive maintenance helps avoid costly repairs, improves energy efficiency, and extends your system’s life. During a tune-up, technicians clean components, check for wear, and spot problems before they turn into emergencies. 5. MYTH: Turning the Thermostat Way Down Cools the House Faster Reality: HVAC systems work at the same speed, regardless of the temperature setting. Cranking your thermostat down to 60°F won’t cool your home faster—it just keeps the system running longer than needed. The best approach? Set a reasonable temperature (like 74°F in summer) and let the system do its job. Final Thoughts HVAC systems are complex, and it’s easy to fall for common myths. Staying informed can help you make smarter decisions, save money, and keep your home comfortable year-round.
