When it comes to your HVAC system, you want to keep your home comfortable while saving as much energy (and money!) as possible. But with so much misinformation out there, it can be tricky to separate HVAC fact from fiction. That’s why I want to debunk some of the most common myths about energy savings and HVAC systems. Read on to learn the truth behind these energy-saving myths!

Myth #1: Closing Vents Saves Energy

You might think closing vents in unused rooms can reduce your energy costs. After all, why cool or heat rooms that aren’t being used? But actually, closing vents disrupts the airflow in your home and puts more strain on your HVAC system. This imbalance can cause your system to run longer to reach the target temperature, using more energy in the process. For optimal efficiency, you’ll want to keep vents open.

Myth #2: Bigger is Always Better

It may be tempting to get the biggest, most powerful HVAC system possible. But a system that’s oversized for your home is inefficient and costly. Oversized units start and stop frequently, preventing them from operating at peak efficiency. Not to mention they cost more upfront! Work with a pro to size your HVAC system correctly based on factors like your home’s size and insulation.

Myth #3: Manual Thermostats Save Power

Programmable thermostats get a bad rap, but they can actually save you up to 10% on heating and 15% on cooling costs. The key is programming your thermostat properly for when you are home, asleep, or away. A smart thermostat takes this a step further by intelligently adjusting the temperature based on your behavior over time. Don’t shy away from an automatic or smart thermostat – it’s one of the easiest ways to save!

Myth #4: Closing Registers Saves Energy

Much like closing vents, the idea here is limiting airflow to unused spaces. But restricted airflow creates problems for your HVAC system. It can cause imbalanced air distribution, uncomfortable hot or cold spots, and moisture buildup leading to mold growth. For comfort and efficiency, you’ll want to leave those registers open.

Myth #5: A Dirty Filter is No Big Deal

It’s easy to let replacing your air filter slide down your priority list. But a dirty, clogged filter forces your system to work much harder to push air through. All that strain can shorten your HVAC system’s lifespan. It’s recommended you change your filter once every 1 to 3 months. Mark it on your calendar if needed! Preventative maintenance like regular filter changes helps your system run smoothly.

Myth #6: Higher Fan Speeds Mean More Cooling

On a hot day, it’s natural to think that blasting the fan will cool your home faster. In reality, a higher fan speed just circulates the existing cooled air around your home faster. For the most efficient cooling, set your fan speed to “auto” and let your AC do its job! The exception is using a whole-house fan at night to bring in cool outdoor air.

Myth #7: Turning Off the System Saves Power

Many people think turning off their AC or heat saves energy. But constantly restarting the system actually uses more power over time than just letting it run! The exception is if you’re leaving your home for multiple days. Overall, it’s best to pick a comfortable temperature and keep the system running consistently.
