When it comes to heating and cooling your home or business, there’s no shortage of misinformation out there. Unfortunately, believing these myths can lead to higher energy bills, reduced system efficiency, and costly repairs. At West Coast Air Conditioning, we’ve been helping customers in Ventura County and beyond since 1984, and we’ve heard just about every HVAC misconception there is. Let’s take a look at some of the most common myths and set the record straight.
Myth 1: You Only Need to Change Your Filter Once a Year
Many homeowners think replacing an air filter annually is enough. The truth is, filters should typically be changed every 1–3 months depending on usage, household size, and whether you have pets or allergies. A clogged filter restricts airflow, making your HVAC system work harder and driving up energy costs.
Myth 2: Bigger HVAC Systems Work Better
It’s easy to assume that a larger system will keep your home more comfortable. In reality, an oversized unit often cycles on and off too frequently, leading to uneven temperatures and increased wear on the equipment. The best system is one that’s properly sized for your space, which our certified technicians at West Coast Air Conditioning can help determine.
Myth 3: Closing Vents in Unused Rooms Saves Energy
This is one of the most widespread HVAC myths. Closing vents actually disrupts airflow, causing pressure imbalances that can strain your system. Instead of saving money, it can shorten the lifespan of your equipment.
Myth 4: Maintenance Isn’t Necessary if the System Works Fine
Even if your HVAC system seems to be running smoothly, skipping maintenance is a mistake. Regular tune-ups prevent small problems from becoming big repairs, improve energy efficiency, and extend the life of your unit. Our team at West Coast Air Conditioning offers customized maintenance programs to keep your system in peak condition.
Myth 5: Thermostat Location Doesn’t Matter
Your thermostat’s placement has a huge impact on how your system performs. If it’s installed near a sunny window, drafty door, or heat-producing appliance, it can give inaccurate readings and cause your HVAC system to run unnecessarily.
