Q: Can dirty air ducts affect air conditioning?

• <div><p>Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.</p></div>

Q: If I don’t want to replace my air conditioner filter, can I clean it?

• <div><p>Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you&rsquo;ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.</p></div>

Q: Do portable ventless air conditioners work?

• <div><p>Yes, but they don&rsquo;t feel the same as an AC-cooled room. You&rsquo;ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren&rsquo;t as capable of quickly cooling large spaces or circulating cold air. </p></div>

Q: Are ductless mini-split AC systems efficient?

• <div><p>It all depends on the unit&rsquo;s SEER (seasonal energy efficiency ratio). A higher <a href="https://www.angi.com/articles/what-does-seer-mean-your-ac.htm">SEER rating</a> means better efficiency and lower costs for your energy bills. </p><p>Take a look at the product you&rsquo;re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.</p></div>

Q: Should you leave the AC fan on or use auto?

• <div><p>For the most part, you should <a href="https://www.angi.com/articles/or-auto-better-thermostat-setting.htm">leave your AC fan in &ldquo;auto&rdquo; mode</a> so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it&rsquo;s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.</p></div>

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

Heating and Air Conditioning questions, answered by experts

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills.

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.
