How do I know if my furnace needs cleaning?

• <div><p>You will know if your furnace needs cleaning if your furnace seems to be working less efficiently than normal. You may notice your bedroom is chilly, but the living room is extremely warm, or perhaps the furnace isn’t heating the house properly at all. The furnace may also make weird noises, like bangs or whistles, or emit a rubbery or smoky smell when it is dirty. Of course, these symptoms could also be signs of other issues, so call in an HVAC pro to take a look as soon as possible.</p></div>

Q: Why is my house always dirty even after cleaning?

• <div><p>Clutter and disorganization can make even a clean house seem dirty. <a href="https://www.angi.com/articles/how-to-declutter.htm">Decluttering unused items</a> will make your home seem cleaner, and putting storage solutions into place will give a house a more organized look and feel. Other things that can make a house feel dirty include stained or faded carpets and upholstery, dirty or dingy walls, chipped paint, and disorganized shelves.</p></div>

Q: Can dirty air ducts make your house smell?

• <div><p>Yes, dirty air ducts can make your house smell. If you have <a href="https://www.angi.com/articles/how-do-i-know-if-i-have-mold-my-air-ducts.htm">mold growing in your ducts</a>, you might notice a musty odor (similar to rotting leaves) coming through your vents when you run your AC. Rodent infestations might smell like ammonia, while an insect problem could create a musty or oily scent.</p></div>

Q: Why are there so many air duct cleaning scams?

• <div><p>Air duct cleaning scams are, unfortunately, so common because the industry is largely unregulated, and technicians don&rsquo;t need to hold licenses in most states. It&rsquo;s also easy for scammers to use scare tactics to claim that your indoor air is potentially unsafe, which makes the service an easy sell. Finally, most homeowners don&rsquo;t have access to their hidden HVAC ducts and can&rsquo;t check on issues themselves, so it&rsquo;s easy to claim that there&rsquo;s mold or debris build-up in there and have it go unchecked.</p></div>

Q: How many return air vents should a house have?

• <div><p>The <a href="https://www.angi.com/articles/how-many-return-vents-do-i-need.htm">number of return air vents</a> a house should have depends on its overall square footage. You'll need one supply vent and one return vent for every 100 to 150 square feet of living space. This means that, ideally, there should be at least one return air vent in every room. However, if the room is 100 square feet or larger, it's better to have two or three. A 2,000-square-foot home should have between 13 and 20 return air vents, in total.</p></div>
