A HEPA filter is a powerful tool for clean air, but the structure doesn’t allow much air to pass through it. That means your HVAC motor must work harder to keep your air pressure consistent, which can result in higher energy bills. That, coupled with the higher cost of HEPA filters, may not make them the best choice for your HVAC system.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

For families or individuals who experience regular or intermittent allergic reactions to airborne particles, a whole-house air filtration system can offer much relief. Regardless of the type of home air filter you install, you'll likely experience some benefits in the form of cleaner indoor air. If you're uncertain, consider a portable filter system to start.

If you don't regularly change your HVAC air filter, it will become clogged with dust, dirt, and other contaminants. This blockage forces the system to work harder to circulate air, leading to several negative consequences. You may experience higher energy bills, poor temperature regulation, reduced air quality, and slower system performance. Over time, this added strain can cause parts to break more frequently, lead to system failure, and ultimately shorten the lifespan of your entire HVAC unit. In some cases, it can also contribute to health problems. It's recommended to change the filter at least every three months.
