HVAC Myths That Cost Homeowners Money
Think you know HVAC? These 7 myths could be draining your wallet. See what’s fact vs. fiction and save money.
Don’t let HVAC myths fool you—get the facts that save you money.
When it comes to heating and cooling your home, misinformation can be surprisingly expensive. From outdated advice to popular misconceptions, believing the wrong HVAC myths can lead to higher energy bills, unnecessary repairs, and reduced system lifespan.
Let’s bust some of the most common HVAC myths so you can protect your home—and your wallet.
Myth #1: Bigger HVAC Systems Are Always Better
Truth: Oversized systems cycle on and off too frequently, leading to uneven temperatures, increased wear and tear, and higher energy use.
What matters most is a properly sized system based on your home’s square footage, insulation, ductwork, and climate.
Always have a licensed HVAC contractor perform a load calculation before installation.
Myth #2: You Only Need to Change the Filter Once a Year
Truth: Most homes need a filter change every 1 to 3 months, especially if you have pets or allergies.
Dirty filters:
Block airflow
Reduce efficiency
Overwork your blower motor
Regular filter changes are one of the cheapest ways to keep your system running smoothly.
Myth #3: Turning the Thermostat Way Down Cools Your Home Faster
Truth: Your HVAC system cools (or heats) at a consistent rate. Setting the thermostat drastically lower won’t speed things up—it just runs longer and wastes energy.
Instead, use programmable thermostats to gradually reach your desired temperature efficiently.
Myth #4: Closing Vents in Unused Rooms Saves Money
Truth: Closing vents can increase pressure in your duct system, causing leaks and reducing efficiency. It may even damage your blower motor.
A better solution: invest in zoned HVAC systems or smart dampers that distribute air based on room usage.
Myth #5: Maintenance Isn’t Necessary Unless Something Breaks
Truth: Preventive maintenance is key to catching problems early and keeping systems efficient.
Regular maintenance can:
Extend equipment life
Prevent breakdowns
Maintain energy efficiency

Myth #6: All HVAC Companies Are the Same
Truth: Not all contractors are licensed, experienced, or customer-focused.
Look for:
Proper licensing (e.g., CSLB in California)
Strong online reviews
Transparent pricing
Emergency service availability

Skipping maintenance can:
Void warranties
Shorten system lifespan
Cause preventable malfunctions
