When it comes to your home’s heating and cooling system, there’s no shortage of advice — and unfortunately, a lot of misinformation too. At Affordable Comfort, we believe in educating our customers, not confusing them. So let’s pull back the curtain and bust some of the most common HVAC myths we hear every day.
Whether you’re shopping for a new system, scheduling seasonal HVAC maintenance, or just trying to lower your energy bills, understanding how your system really works can save you time, money, and stress.
Myth #1: “If it ain’t broke, don’t fix it.”
Truth: Waiting until your system breaks down is one of the most expensive ways to handle HVAC maintenance.
Regular HVAC tune-ups keep your system running efficiently and help prevent surprise breakdowns — especially during peak heating or cooling seasons.
Why it matters: Preventative maintenance extends the life of your HVAC system, catches small issues before they become major repairs, and helps reduce your energy bills.
Myth #2: “Bigger HVAC systems are always better.”
Truth: An oversized system can short-cycle, meaning it turns on and off too frequently. That leads to poor humidity control, uneven temperatures, and higher utility bills.
What you actually need: A properly sized HVAC system based on a professional load calculation. This ensures comfort, energy efficiency, and a longer-lasting unit.
Myth #3: “Closing vents in unused rooms saves energy.”
Truth: Closing vents actually disrupts airflow, increases pressure in the duct system, and can even damage your HVAC equipment over time.
Instead, do this: If you’re trying to control temperatures in specific rooms, ask us about zoning systems or smart thermostats.
Myth #4: “AC units just need refrigerant top-offs every year.”
Truth: If your system needs a refrigerant refill, there’s likely a leak — and that’s a problem that needs to be fixed, not ignored.
Refrigerant doesn’t get “used up” like fuel. A well-maintained system should not lose refrigerant.
Myth #5: “The lower you set the thermostat, the faster it cools.”
Truth: Your HVAC system works at the same speed no matter what temperature you set. Setting it lower won’t cool your home faster — it’ll just run longer and use more energy.
Pro tip: Use a programmable or smart thermostat to manage your comfort efficiently, especially when you’re not home.
