Misconceptions about your HVAC system don’t just lead to minor inefficiencies—they can significantly drain your wallet and compromise comfort. Whether you’re a homeowner trying to keep monthly bills in check or a commercial property manager focused on operational continuity, falling for these common HVAC myths will cost you money.
From over-relying on ceiling fans to closing vents in unused rooms, many “common-sense” practices are in fact sabotaging your air conditioner. Let’s break down these myths and explore how proper maintenance and smart upgrades from Dynamic Air Systems can keep you cool—without burning through your cash.
Myth #1: Bigger HVAC Systems Work Better
The Myth
“Go big or go home”—many believe that larger air conditioners cool more effectively.
The Truth
An oversized unit short cycles, meaning it turns on and off too often without fully dehumidifying the air. This reduces comfort, increases wear, and spikes your energy usage.
Why It Costs You
Short cycling increases energy bills and shortens your system’s lifespan. You’re paying for power and repairs you shouldn’t need.
How to Fix It:
Dynamic Air Systems provides HVAC system installations tailored to your space using load calculations, not guesswork. This ensures cool air without waste.
Myth #2: Turning the Thermostat Way Down Cools the House Faster
The Myth
Crank it down and it will cool faster, right?
The Truth
Your air conditioner cools at the same rate regardless of the setting. Setting the thermostat too low just keeps it running longer.
Why It Costs You
You’re using more energy without getting faster results—just higher bills.
How to Fix It:
Invest in smart thermostat installation and optimization. Dynamic Air Systems sets up programmable thermostats that adjust temperatures based on your schedule, saving energy and boosting comfort.
Myth #3: Close Vents in Unused Rooms to Save Energy
The Myth
Shut the vents, save the dollars!
The Truth
Closing vents disrupts airflow, causes pressure build-up, and can lead to short cycling or duct leaks.
Why It Costs You
Damaged ducts and strained equipment lead to more repairs and decreased efficiency.
How to Fix It:
Let Dynamic Air Systems assess your system and install zoned cooling solutions like mini-split systems for targeted temperature control.
Myth #4: Air Filters Only Matter for Allergies
The Myth
Air filters are only important for allergy-prone households.
The Truth
Dirty filters choke your system, reduce indoor air quality, and make your unit work harder.
Why It Costs You
Your system burns more power and may overheat, leading to higher energy bills and premature breakdown.
How to Fix It:
Sign up for Dynamic Air Systems’ preventative maintenance contracts—we inspect and replace air filters regularly to keep your system running efficiently.
Myth #5: Maintenance Is Optional Until Something Breaks
The Myth
“If it ain’t broke, don’t fix it.”
The Truth
Skipping maintenance is like never changing your car’s oil. You’re inviting expensive breakdowns.
Why It Costs You
Unaddressed issues reduce system lifespan and lead to emergency repairs.
How to Fix It:
Dynamic Air Systems’ commercial HVAC service contracts and residential maintenance plans are designed to detect issues early—ensuring comfort, safety, and long-term savings.
