Debunking Common HVAC Myths

When it comes to HVAC systems, there’s no shortage of misinformation. Over the years, homeowners have picked up a number of common HVAC myths that can lead to costly decisions, uncomfortable indoor temperatures, and energy waste. At Cousin's Air, Inc., we believe in empowering our customers with accurate information—because the more you know, the more comfortable (and efficient) your home can be.

Myth #1: Bigger HVAC Systems Are Always Better

Many assume that installing a larger HVAC system will cool or heat their home faster. In reality, an oversized unit can short-cycle—turning on and off frequently—which puts stress on the system and leads to uneven temperatures and higher energy bills. At Cousin's Air, Inc., our team ensures your system is properly sized for your space and cooling needs.

Myth #2: You Only Need to Change Your Filter Once a Year

In South Florida’s humid climate, air filters can clog more quickly than expected. A dirty filter restricts airflow, reduces efficiency, and strains your HVAC system. We recommend checking your filter monthly and replacing it every 1–3 months depending on usage and household conditions.

Myth #3: HVAC Maintenance Isn’t Necessary Unless Something Breaks

Preventative maintenance is key to extending your system’s lifespan and avoiding surprise breakdowns. Just like you wouldn’t drive your car for years without an oil change, your AC needs regular tune-ups. Our team at Cousin's Air, Inc. offers maintenance plans that keep your system running at its best year-round.

Myth #4: Closing Vents in Unused Rooms Saves Energy

It might seem logical to close vents in unused areas, but this can actually disrupt airflow and create pressure imbalances that strain your HVAC system. Instead of saving energy, you may end up causing damage and increasing utility costs.

Myth #5: Thermostat Settings Can Speed Up Cooling or Heating

Setting your thermostat to extreme temperatures won’t cool or heat your home faster. Your HVAC system works at a consistent rate regardless of the number. It’s best to set your thermostat to a comfortable level and let it do its job efficiently.
