When it comes to heating and cooling, there’s no shortage of advice but not all of it is true. From “closing vents saves energy” to “bigger systems work better,” homeowners often fall for common HVAC myths that can actually hurtefficiency and comfort.
We asked our HVAC experts at Climate Pro’s Heating and Cooling to set the record straight. Here are the top heating and cooling myths busted once and for all.
Myth #1: Closing Vents in Unused Rooms Saves Energy
It sounds logical if you close vents, your system doesn’t have to work as hard. Unfortunately, that’s not how HVAC systems are designed. Closing vents increases pressure in your ductwork, which can lead to leaks, restricted airflow, and system strain.
If your goal is efficiency, scheduling regular HVAC duct inspections and ensuring ducts are properly sealed will make a far bigger difference.
Myth #2: The Bigger the HVAC System, the Better the Performance
A larger unit isn’t always better. In fact, an oversized HVAC system will cycle on and off too frequently, causing temperature fluctuations, humidity issues, and higher energy bills.
The right size depends on your home’s insulation, square footage, and layout something only certified HVAC expertscan calculate accurately during a professional assessment.
Myth #3: You Only Need Maintenance When Something Breaks
Waiting until your system fails before calling for help often leads to costly emergency HVAC repairs. Regular maintenance, on the other hand, helps detect minor issues before they turn into major problems.
Routine HVAC services, including cleaning coils, checking refrigerant levels, and inspecting electrical components, keep your unit performing efficiently year-round.
Myth #4: Air Filters Only Need Changing Once a Year
Dirty filters restrict airflow and force your HVAC system to work harder, reducing efficiency and increasing wear and tear. In most cases, filters should be replaced every 1–3 months, depending on usage and whether you have pets or allergies.
A clogged filter can also worsen indoor air quality something easily improved with a UV system for HVAC, which kills bacteria, mold spores, and allergens circulating in the air.
Myth #5: Commercial HVAC Systems Don’t Need Regular Inspections
Business owners sometimes assume that commercial systems can handle more stress without frequent checks. In reality, commercial HVAC units endure heavier use and require consistent maintenance to avoid downtime and costly breakdowns.
If you’ve ever searched for commercial HVAC contractors near me, you know how valuable it is to have a reliable partner like Climate Pro’s Heating and Cooling to keep your systems running smoothly.
Myth #6: Duct Cleaning Isn’t Necessary if Airflow Seems Fine
Even if your air seems clean, contaminants can still build up inside your ductwork over time. Dust, mold, and debris can circulate through your home, affecting both air quality and energy efficiency.
That’s why an annual hvac duct inspection is essential; it ensures your system delivers clean air efficiently and safely.
Myth #7: Thermostat Location Doesn’t Matter
The thermostat is your HVAC system’s command center. Placing it near direct sunlight, windows, or vents can trick it into thinking your home is warmer or cooler than it really is.
For accurate temperature control, thermostats should be installed in a central, shaded area ideally by a professional as part of your regular HVAC services.
