Q: Is FPR better than MERV?

• <div><p>No, FPR isn&rsquo;t necessarily better than MERV. Both systems measure an air filter&rsquo;s effectiveness, but they express it on different scales. FPR ratings range from 1 to 12, while MERV ratings run between 1 and 20. However, some people might find FPR ratings easier to understand since they&rsquo;re color-coded and have descriptors like &ldquo;good,&rdquo; &ldquo;better,&rdquo; and &ldquo;premium.&rdquo;</p><p> </p></div>

Q: How often should the air ducts in your home be cleaned?

• <div><p>Air ducts should be cleaned every three to five years, though the frequency can vary based on factors such as household conditions and local environmental factors. For homes with pets, smokers, or high dust levels, more frequent cleanings every two to three years would be necessary to maintain optimal air quality. If you notice persistent odors, significant dust buildup, or signs of mold or rodent activity, schedule a cleaning sooner.</p></div>

Q: How do you fix poor air ventilation?

• <div><p>The simplest way is opening the windows so that stale air or fumes can easily escape and fresh air flows in. If opening your windows isn't an option, ceiling fans and box fans can clear particles out and get the air moving. Air purifiers can also clean the air while making it circulate better.</p></div>

Q: Do repairs include ductwork inspection?

• <div><p>Yes, professionals check venting ducts to ensure proper air circulation and prevent moisture buildup.</p></div>
