6 Common HVAC Myths Debunked
Aug 30, 2024
When it comes to keeping your home comfortable, your HVAC system plays a crucial role. But with so much information floating around, it can be hard to separate fact from fiction. As your local HVAC experts, we’ve heard it all, and we’re here to set the record straight. Let’s debunk some of the most common HVAC myths so you can keep your system running smoothly and your home cozy.
Myth 1
Bigger HVAC Systems Are Always Better
The idea behind this myth is simple—more power means better performance. Many homeowners believe that if a small system works well, then a bigger one must be even better, right? The thinking is that a larger HVAC system will heat or cool your home faster, providing quicker comfort.
The Reality: An oversized HVAC system can actually cause more problems than it solves. It might heat or cool your space faster, but it won’t run long enough to properly remove humidity or distribute the air evenly. This can lead to uneven temperatures, a system that turns on and off frequently (known as short cycling), and even higher energy bills. What you really need is a system that’s just the right size for your home.
Our Tip: Before you invest in a new system, have a professional perform a load calculation to determine the ideal size for your space. Trust us—this step is worth it for your comfort and your wallet!
Myth 2
You Only Need to Change your Air Filter Once a Year
AC air filters are often out of sight, out of mind, so it’s easy to assume they don’t need frequent attention. Some homeowners believe that changing the filter annually is enough to keep the system running smoothly. After all, if the system is still working, why bother?
The Reality: Your HVAC filter works hard to trap dust, dirt, and other particles, keeping your air clean and your system running efficiently. Over time, that filter gets clogged, and if you don’t change it regularly, it can reduce airflow, make your system work harder, and even lead to costly repairs.
Our Tip: Check your air filter every month and replace it at least every three months—more often if you have pets or allergies. It’s a simple task that can save you big headaches down the road.
Myth 3
Closing Vents in Unused Rooms Saves Energy
This myth comes from the idea that you can conserve energy by not heating or cooling rooms you don’t use. The logic seems sound: If no one’s using the room, why waste energy on it? So, people close the vents in these rooms, hoping to save on their utility bills.
The Reality: Modern HVAC systems are designed to work with a specific amount of airflow. When you close vents, you create pressure imbalances in the system, which can lead to duct leaks, reduced efficiency, and even damage to your system.
Our Tip: Keep those vents open, even in unused rooms. If you’re looking to save energy, consider a zoning system that allows you to control temperatures in different areas of your home without causing issues.
Myth 4
Thermostat Placement Doesn’t Matter
Many people think that as long as the thermostat is somewhere in the house, it will do its job just fine. After all, the thermostat just needs to read the temperature, right? So, whether it’s near a window, in a sunny spot, or close to the kitchen, it shouldn’t matter much—or so the myth goes.
The Reality: Where you place your thermostat can have a big impact on how well your HVAC system works. If it’s in a spot that gets direct sunlight, near a window, or close to a heat source, it can give a false reading, causing your system to run too much or too little.
Our Tip: Make sure your thermostat is placed in a central location away from direct sunlight and other heat sources. This will help it get a more accurate reading of your home’s temperature.
Myth 5
Maintenance Isn’t Necessary if My System is Working Fine
This myth stems from the idea that if it ain’t broke, don’t fix it. If your HVAC system is keeping your home comfortable, why spend money on maintenance? It’s easy to overlook maintenance when everything seems to be working just fine.
The Reality: Just like your car, your HVAC system needs regular check-ups to keep it running efficiently. Without maintenance, small issues can turn into big problems, leading to breakdowns, higher energy bills, and a shorter system lifespan.
Our Tip: Schedule regular AC maintenance with a professional HVAC technician. A little upkeep now can save you from major HVAC repairs later.
Myth 6
All HVAC Systems Are the Same
Some homeowners believe that all HVAC systems are created equal and that any system will do the job, as long as it’s the right size. This myth leads to a lack of research when purchasing a new system, potentially resulting in a poor match for their home’s needs.
The Reality: Not all HVAC systems are created equal, and the right one for your neighbor might not be the best fit for you. There are several types of HVAC systems out there—central air, ductless mini-splits, heat pumps, and more—each with its own set of benefits. The best system for your home depends on factors like size, layout, and even the climate in our area.
