Common HVAC Myths Debunked: What You Really Need to Know in New Lenox, IL

When it comes to keeping your home comfortable year-round, there’s no shortage of advice—especially about your HVAC system. But not everything you hear is true. Many homeowners in New Lenox, IL, rely on secondhand tips or online “hacks” that can do more harm than good to their heating and cooling systems. Understanding the truth behind these myths can save you money, energy, and frustration.

Your air conditioning and heating and air conditioning units are major investments, and taking care of them correctly ensures they perform efficiently for years. Unfortunately, common misconceptions can lead to costly mistakes. From thermostat settings to maintenance routines, let’s set the record straight on some of the most widespread HVAC myths and what you should actually do to protect your system.

Myth 1: You Don’t Need to Change Your Air Filter Often

This is one of the most common HVAC myths out there. Many homeowners think air filters can last for months without being changed. In reality, dirty filters restrict airflow, force your system to work harder, and reduce efficiency. During peak seasons in New Lenox, filters should be checked monthly and replaced every one to three months, depending on your home’s air quality.

Regularly changing your filter not only improves air conditioning performance but also enhances indoor air quality. A clean filter helps prevent dust and allergens from circulating throughout your home—something every family member can appreciate.

Myth 2: Closing Vents Saves Energy

It might seem logical to close vents in unused rooms to reduce energy use, but this can actually strain your heating and ac system. Modern HVAC systems are designed to balance airflow throughout the house. Closing vents disrupts that balance, leading to pressure buildup and potential duct leaks. The result? Higher energy bills and uneven comfort.

Instead, consider using a zoned HVAC system if you want to control temperatures in different rooms more efficiently. These systems are designed to handle varying demands and help you save on utility costs.

Myth 3: Bigger HVAC Systems Perform Better

Many people assume that a larger HVAC system means better performance, but that’s not the case. An oversized unit will cycle on and off too frequently, causing temperature swings and unnecessary wear on the system. On the other hand, an undersized unit will run constantly, struggling to maintain a comfortable temperature.

The best solution is to work with a professional hvac repair and installation team in New Lenox, IL, like Zark Heating & Cooling Inc., who can perform accurate load calculations and recommend the perfect system size for your home.

Myth 4: Maintenance Isn’t Necessary Until Something Breaks

Waiting until your system breaks down is one of the costliest mistakes you can make. Regular tune-ups keep your heating and air conditioning running efficiently and can extend the lifespan of your equipment. Routine inspections also help technicians catch small issues before they turn into major problems.

Experts recommend scheduling professional maintenance twice a year—once in spring for your air conditioning system and again in fall for your heating and cooling equipment. Check out the U.S. Department of Energy for more details on why preventive maintenance is essential.

Myth 5: All HVAC Technicians Offer the Same Services

Not all HVAC service providers are equal. Experience, certification, and reputation matter when it comes to your comfort and safety. A trusted local company like Zark Heating & Cooling Inc. provides comprehensive services air conditioner and cooling and heating solutions that are tailored to New Lenox homeowners’ unique needs.
