Q: What happens if you don’t open the flue?

• <div><p>Failing to open your flue can lead to serious health hazards if you start a fire because the smoke will back up into your home. Breathing fire smoke, even in relatively small quantities, is bad for human lungs, and smoke can also irritate your nasal passages and eyes. Furthermore, smoke can cause damage to your interior fixtures and furnishings, at the very least leaving an unpleasant smoky smell for a long time. In short: If your flue isn&rsquo;t open (or you&rsquo;re not sure if it is or not), don&rsquo;t start a fire to find out!</p></div>

Q: How do I ensure my ducts and vents are properly maintained?

• <div><p>To optimize airflow and energy efficiency, regularly clean vents and replace air filters, schedule periodic professional duct inspections, and seal any visible leaks. Proper maintenance prolongs ductwork longevity and performance.</p></div>

Q: What maintenance ensures exhaust systems function efficiently?

• <div><p>Regular cleaning, sealing ductwork, and ensuring proper airflow paths keep systems functioning optimally, maintaining energy efficiency.</p></div>

Q: Is it OK to never clean air ducts?

• <div><p>Some experts say you should clean your air ducts every three to five years, but regular air duct cleaning is something you may never need to do. The EPA has shown no noticeable health benefits to cleaning your ducts regularly, so as long as you don&rsquo;t encounter any major problems and maintain your HVAC system, you won&rsquo;t need to clean your air ducts.</p></div>
