Q: What happens if you don't change your HVAC filter?

• <div><p>If you do not regularly change your HVAC filter, it will become clogged with dust, dirt, and other contaminants. This blockage forces the system to work harder to circulate air, leading to higher energy bills, poor temperature regulation, and increased wear on parts, which can cause more frequent breakdowns and shorten the system's overall lifespan. Additionally, a dirty filter that no longer traps contaminants can lead to poor indoor air quality, potential health problems, and even complete system failure.</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 use a carbon filter if I don’t have an exhaust?

• <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. This method allows you to keep your enclosed garden space sealed from the outside environment.</p></div>

Q: Can I repair a central air cleaner myself?

• <div><p>Simple filter changes can be done DIY, but professionals should handle motor repairs, sensor issues, and airflow problems.</p></div>

"within minutes, I received a call from the very friendly and professional Michelle. Calling me all the way from California! Michelle explained the services she could and could not offer in terms of my needed furniture repair. And while she cannot help me specifically with my furniture issue, she offered a very generous solution: she is going to send me leather dye for the scratched ottoman and talk me through the repair, should I need help! Michelle also explained that she deals with customers all over the country, in need of leather and purse and clothing repair, cleaning, and restoration. Based on my extremely positive experience with Michelle, I will be sure to call her in the future when I need help with fur, leather or suede goods!!!"
