Does my HVAC technician have to be NATE certified?

• <div><p>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 <a href="https://www.angi.com/articles/common-types-of-HVAC-systems.htm">different types of HVAC systems</a>, 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. </p></div>

Can I use a carbon filter if I don’t have an exhaust?

• <div><p>Even if you don’t have an exhaust, you can still use a carbon filter in line with a duct fan. This method is known as “scrubbing” because it cleans particles from the air and recirculates the air within your space. This method allows you to keep your enclosed garden space sealed from the outside environment.</p></div>

Q: How often should MERV 11 filters be changed?

• <div><p>Air filters with a MERV rating of 11 or higher need to be changed every three to six months. If your filters are incredibly strained because of environmental factors, such as living in a smoggy, pollen-rich area with a large household, you may need to change your filters every two months regardless of the MERV rating. </p></div>

Q: Can I run my AC with a dirty filter?

• <div><p>Your air conditioner can temporarily run with a dirty filter, but it won&rsquo;t work as efficiently. It will need to work harder to blow cool air throughout the room or house, and this can eventually cause the air conditioner to overheat or die prematurely. It&rsquo;s much more cost-effective to clean or replace filters than to pay higher utility bills each month and replace the entire AC unit more often.</p></div>

• <div><p>Even if you don&rsquo;t have an exhaust, you can still use a carbon filter in line with a duct fan. This method is known as &ldquo;scrubbing&rdquo; because it cleans particles from the air and recirculates the air within your space.

Q: Is no air filter better than a dirty one?

• <div><p>No, running your furnace without an air filter isn&rsquo;t better than running it with a dirty filter. Even if it&rsquo;s dirty, a filter will still prevent particles from blowing around your ducts and your house. However, neither of these options is good for your furnace or your health. Replace your filter once every one to three months for optimal furnace performance and air quality. </p></div>
