5 HVAC Maintenance Mistakes Green Bay Homeowners Make
When it comes to staying comfortable through Wisconsin’s unpredictable seasons, your HVAC system does a lot of heavy lifting. But even the most dependable systems need a little TLC to run efficiently. Unfortunately, many homeowners unknowingly make small HVAC maintenance mistakes that can turn into big repair bills down the road.
At Richard’s Heating & Cooling, we’ve seen it all — from clogged filters to overworked furnaces. So we’re breaking down the top 5 HVAC maintenance mistakes Green Bay homeowners make and how to avoid them.
Whether you’re dealing with muggy summer days or bone-chilling winter nights, these tips will help you stay comfortable, cut energy costs, and extend the life of your system.
1. Skipping Regular Filter Changes
It might seem simple, but changing your air filter regularly is one of the most important things you can do for your HVAC system. A dirty filter restricts airflow, forcing your system to work harder than it should.
Not only does this reduce efficiency, but it also impacts indoor air quality — especially for households with pets or allergy sufferers.
Pro Tip: Check your filter every 1-3 months, depending on usage. If it looks dirty, it’s time for a replacement.
2. Ignoring Unusual Noises or Odors
Strange rattling? Burning smells? Loud banging or hissing? These are all warning signs that something’s not right with your HVAC system.
It can be tempting to wait it out and hope the issue resolves itself, but the longer you ignore it, the more damage could be happening behind the scenes. What starts as a loose part or minor buildup can quickly snowball into a full-blown breakdown.
Bottom line: If your system sounds or smells different, don’t wait — call a professional to assess the issue early.
3. Closing Too Many Vents
We get it — it might seem logical to close off vents in unused rooms to save on energy. But closing too many vents can actually backfire.
HVAC systems are designed for balanced airflow. When you shut vents, you disrupt that balance and increase pressure in the ductwork. This added strain can cause leaks, reduce efficiency, and even damage key components like the blower motor.
Tip: Instead of closing vents, consider zoning upgrades or an assessment of current ductwork to better manage comfort and costs.
4. Not Scheduling Annual Tune-Ups
Your HVAC system runs hard year-round — especially in a place like Green Bay, where the seasons swing wildly. That’s why annual maintenance is so important.
A professional tune-up before peak heating or cooling season can catch minor issues early, keep your system clean, and ensure it’s running at peak performance.
Routine maintenance isn’t just about avoiding breakdowns — it also extends the life of your system and helps you save on monthly energy bills.

5. Delaying Thermostat Upgrades
Still using an old manual thermostat? You could be missing out on major energy savings.
Smart thermostats allow you to set schedules, control your system remotely, and learn your preferences over time. They’re a game-changer for comfort and efficiency — especially during Green Bay’s temperature swings.
At Richard’s Heating & Cooling, we can help recommend and install a smart thermostat that fits your lifestyle and budget.
