• <div><p>If you have dirty vent covers, clogged air filters, noisy air ducts, or weak airflow, it might be <a href="https://www.angi.com/articles/3-signs-its-time-find-air-duct-cleaner.htm">time to get your air ducts cleaned</a>.

Q: How often do you need to clean your HRV filter?

• <div><p>You should remove and clean your HRV filters about once a month, as debris will build up quickly, especially on the fresh air side of the ductwork. Even with routine cleaning, you should plan to replace the filters at least once a year or more often if you find that they&rsquo;re getting dirty quickly during operation.</p></div>

Q: What is the most common cause of poor airflow in a duct system?

• <div><p>For most homes, the common causes of poor airflow in a duct system are blockages, typically from dust, debris, or buildup. Other factors include leaky or disconnected ducts, improper duct sizing, and clogged air filters. These issues restrict airflow, reducing HVAC efficiency.</p></div>

Q: Does my chimney impact my HVAC system?

• <div><p>In most homes, your chimney and HVAC are separate from each other. However, you can use your chimney to save on heating costs in the winter. Turn off your HVAC system and start a cozy fire, then watch the electric bills drop during the coldest months. Make sure your flue is closed when not in use so that you don&rsquo;t end up pumping heat or cool air from your system outside.</p></div>

Q: How does dry mode affect indoor air quality?

• <div><p>Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.</p></div>
