Common Myths About HVAC Systems

When it comes to heating and air conditioning, there’s no shortage of myths that can lead to costly decisions or even damage your HVAC system. At All-Phase Heating & Cooling, we believe that informed homeowners make the best choices for their comfort and energy savings. That’s why we’re here to clear up some of the most common HVAC misconceptions.

Myth #1: You Only Need to Change Your Filter Once a Year

This is one of the most common and misleading HVAC myths. In reality, your air filter should be checked every month and changed every 1 to 3 months, depending on your system, home size, pets, and air quality. A dirty filter restricts airflow, reduces efficiency, and can even lead to breakdowns. Staying on top of this simple task can save you from expensive repairs.

Myth #2: Closing Vents in Unused Rooms Saves Energy

Many homeowners believe that closing vents in unused rooms can reduce energy use. However, your HVAC system is designed to balance air throughout your entire home. Closing vents can cause pressure imbalances that strain your system, reduce efficiency, and lead to uneven temperatures or duct leaks. Instead of closing vents, talk to our team at All-Phase Heating & Cooling about zoning solutions or system upgrades that truly improve efficiency.

Myth #3: Bigger HVAC Systems Are Always Better

When it comes to HVAC systems, bigger isn’t always better. Oversized units may cool or heat your home quickly, but they’ll short-cycle, turning on and off frequently. This leads to increased wear and tear, higher energy bills, and inconsistent comfort. At All-Phase Heating & Cooling, we take the time to properly size your system based on your home’s square footage, layout, insulation, and more.

Myth #4: Maintenance Isn’t Necessary Until Something Breaks

Waiting for something to go wrong before calling for help is a surefire way to face costly repairs. Regular HVAC maintenance keeps your system running efficiently, catches small issues before they become big problems, and extends your system’s lifespan. Our preventative maintenance services are designed to keep your HVAC investment in peak condition year-round.

Myth #5: Thermostat Placement Doesn’t Matter

Your thermostat is the brain of your HVAC system, and its location matters. If it's placed in direct sunlight, near windows, or close to vents, it can misread the temperature and make your system work harder than it needs to. Our technicians can assess the best placement for your thermostat to ensure accurate readings and better comfort control.
