As the temperature fluctuates in Central New Jersey, our reliance on heating, ventilation, and air conditioning (HVAC) systems becomes more pronounced. However, amid the chilly winters and scorching summers, numerous misconceptions surround these indispensable systems. At Green Apple Mechanical NJ, we believe in empowering our clients with knowledge. Let’s debunk some common HVAC myths and shed light on the facts.

Myth 1: Turning Off the HVAC System When Not at Home Saves Energy

Fact: Contrary to popular belief, turning off your HVAC system entirely can lead to increased energy consumption. The system has to work harder to reach the desired temperature when you return, canceling out any potential savings. Instead, consider adjusting the thermostat to a slightly higher or lower temperature when you’re away for extended periods.

Myth 2: Closing Vents in Unused Rooms Boosts Efficiency

Fact: Many homeowners think that closing vents in unused rooms directs air to the spaces they frequent, making the system more efficient. However, modern HVAC systems are designed to maintain a balanced airflow. Closing vents can disrupt this balance, leading to increased pressure in the ducts and potential damage to the system. Keep vents open for optimal performance.

Myth 3: Regular Maintenance Isn’t Necessary

Fact: Neglecting regular maintenance is a common misconception that can result in costly repairs and decreased efficiency. Routine check-ups by a Green Apple professional technician ensure that your HVAC system operates at its best. From checking refrigerant levels to cleaning filters, proactive maintenance extends the lifespan of your system and prevents unexpected breakdowns.

Myth 4: Lowering the Thermostat Heats or Cools Your Home Faster

Fact: Your HVAC system operates at a consistent rate, regardless of the temperature setting. Lowering the thermostat doesn’t accelerate the heating or cooling process; it only changes the target temperature. Setting an extreme temperature won’t speed up the system; it may only result in overshooting the desired temperature and wasting energy.

Myth 5: The Bigger the HVAC System, the Better

Fact: Size matters, but bigger isn’t always better when it comes to HVAC systems. An oversized system can lead to short cycling, where the unit turns on and off frequently, reducing efficiency and increasing wear and tear. A properly sized system, determined by a Green Apple professional, ensures optimal performance and energy efficiency.
