10 Common HVAC Myths Debunked by NJ Experts

When it comes to heating, ventilation, and air conditioning (HVAC) systems, there's a lot of misinformation out there. These myths can lead to inefficient energy use and costly mistakes. To help you separate fact from fiction, we've gathered insights from NJ experts to debunk some common HVAC myths.

Myth 1: Bigger is Always Better

One of the most prevalent myths is that a bigger HVAC system will perform better. However, an oversized system can lead to frequent cycling, which wastes energy and can shorten the lifespan of the unit. It's crucial to have a system that's properly sized for your home.

Understanding the Right Size

Professional HVAC technicians can conduct a load calculation to determine the appropriate size for your system. This ensures optimal efficiency and comfort.

Myth 2: Close Vents in Unused Rooms to Save Energy

Many believe that closing vents in unused rooms will save energy, but this can actually harm your system. Closing vents increases pressure, which can cause leaks and reduce efficiency.

Proper Airflow is Key

Maintaining balanced airflow throughout your home is essential for the system's performance. Instead of closing vents, consider zoning systems for better control.

Myth 3: Regular Maintenance Isn't Necessary

Skipping regular maintenance is a common mistake. Routine check-ups can prevent small issues from becoming major repairs and keep your system running efficiently.

Benefits of Regular Maintenance

Regular maintenance can extend the lifespan of your HVAC system, improve air quality, and reduce energy bills. It's a worthwhile investment.

Myth 4: Thermostat Placement Doesn't Matter

Thermostat placement can significantly impact your system's efficiency. Placing it near heat sources or in direct sunlight can lead to incorrect readings and inefficient heating or cooling.

Ideal Thermostat Placement

Experts recommend placing the thermostat on an interior wall, away from direct sunlight and drafts, to ensure accurate temperature readings.

Myth 5: Air Filters Only Need to Be Changed Once a Year

Changing your air filter once a year is not enough. Dirty filters restrict airflow, making your system work harder and increasing energy consumption.

Regular Filter Changes

Filters should be checked monthly and replaced every 1-3 months, depending on use and manufacturer recommendations.

Myth 6: Setting the Thermostat Higher Heats the Home Faster

Craning up the thermostat doesn't heat your home any faster. It only makes the system run longer, using more energy.

Efficient Heating Practices

Set your thermostat to the desired temperature. Consider using a programmable thermostat for better energy management.

By understanding these common myths, you can make informed decisions about your HVAC system and improve efficiency, comfort, and cost-effectiveness. Be sure to consult with certified HVAC professionals to optimize your system’s performance.
