Living in Phoenix, Arizona means your HVAC system plays a crucial role in home comfort, especially during those scorching summer months. But many homeowners unknowingly believe HVAC myths that can lead to higher energy bills, poor performance, and premature breakdowns.
Let’s bust the most common HVAC misconceptions Arizona homeowners should stop believing—and help you make smarter decisions for your home’s comfort and efficiency.
Myth 1: Bigger HVAC Systems Are Always Better
The Truth: Oversized HVAC systems actually hurt efficiency. Many homeowners think that installing a larger air conditioner will cool their homes faster. While it might cool the air quickly, it will short cycle—turning on and off too frequently—which wastes energy and increases wear and tear on the unit.
In Arizona’s hot climate, a properly sized system is critical. Your HVAC unit should be chosen based on your home’s square footage, insulation, window placement, and sun exposure.

Myth 2: You Only Need to Change the Air Filter Once a Year
The Truth: Arizona’s dusty desert environment means your HVAC filters work harder than average. You should be checking and replacing your filters every 1 to 3 months, depending on use and air quality conditions.
Dirty filters restrict airflow, reduce efficiency, and can cause costly system failures.

Myth 3: Closing Vents in Unused Rooms Saves Energy
The Truth: This myth sounds logical but actually hurts your HVAC system. Your ductwork is designed to balance airflow throughout your entire home. When you close vents, it increases pressure in the system and can cause leaks, damage, or inefficiencies.
If you want to control temperatures in specific zones, consider upgrading to a zoned HVAC system instead.

Myth 4: Maintenance Isn’t Necessary Unless Something Breaks
The Truth: This is one of the most dangerous myths homeowners believe. Skipping routine HVAC maintenance is like skipping oil changes for your car. Preventive service catches small issues before they become expensive repairs—and keeps your system running longer.
In fact, the U.S. Department of Energy confirms that properly maintained HVAC systems can cut energy use by up to 15%.

Myth 5: Turning the Thermostat Way Down Cools Faster
The Truth: Your HVAC system cools at a consistent rate regardless of how low you set the thermostat. Cranking it down to 60°F won’t make it reach 75°F any faster—it only forces your unit to work longer, wasting energy.
Instead, consider installing a smart thermostat that adjusts to your schedule and Phoenix’s climate patterns.
