5 HVAC Myths About Fall Maintenance Debunked

Fall is upon us—crisp air, pumpkin-spice everything, and the familiar hum of your heating system warming up for the season. But along with all the cozy vibes comes a flurry of myths about HVAC maintenance that can leave you in the cold, quite literally. Don’t fall for these common misconceptions! We’re here to debunk five of the most misleading myths about fall HVAC maintenance, so you can keep your home comfy and your system running smoothly.
Myth #1: “My Heating System Was Fine Last Year, So It’s Fine This Year.”
Think of your heating system like your favorite fall sweater—it worked great last year, but if you don’t check it for wear and tear, you might end up with holes (or cold spots!). Just because your system ran without issues last season doesn’t mean it’s ready to tackle another chilly stretch. Regular maintenance is key to spotting problems early before they turn into pricey repairs or, worse, leave you without heat when the temperatures drop.
Myth #2: “I Only Need to Change My Air Filter in the Summer.”
While it’s true that summer AC use can clog up your air filter, fall is not the time to slack off. Fall allergens, dust from heating systems kicking back on, and even pet dander can clog those filters quickly. A dirty filter makes your system work harder, leading to higher energy bills and a stressed-out HVAC unit. Change those filters every 1-3 months—even in the fall—to keep the air clean and your system efficient.
Myth #3: “Closing Vents in Unused Rooms Will Save Energy.”
This one seems logical at first glance—why heat rooms no one’s using, right? But closing off vents can actually *increase* energy use. Modern HVAC systems are designed to distribute air evenly throughout your home. When you close a vent, the system has to work harder to maintain balance, causing strain on the unit and potentially leading to damage. Instead, use a programmable thermostat to control the temperature in different zones for better efficiency.
Myth #4: “I Can Skip Maintenance Because My Heating System Isn’t That Old.”
Just like a new car still needs oil changes, your newer HVAC system needs regular check-ups to stay in top shape. Skipping routine maintenance, even on a new system, can void warranties and shorten its lifespan. And let’s be honest, you don’t want to be that person who says, “But it was practically new!” when the furnace breaks down mid-blizzard.
Myth #5: “I Can DIY My HVAC Maintenance with a Quick YouTube Search.”
Sure, YouTube is great for learning how to make pumpkin muffins, but HVAC maintenance? Not so much. While there are basic tasks you can handle—like changing air filters—more complex jobs, like checking electrical connections or testing furnace performance, should be left to the pros. A certified technician knows what to look for and can spot issues before they snowball into bigger, more expensive problems. Plus, you’ll save yourself the headache (and potential danger) of tinkering with equipment you’re not familiar with.

Now that you know the truth about fall HVAC maintenance, it’s time to take action. A well-maintained system is the secret to a warm and worry-free winter. Ready to give your HVAC some TLC?
