Q: Are AC units with a lower SEER rating being phased out?

• <div><p>The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.</p></div>

Q: Does flex duct reduce airflow?

• <div><p>When first installed, flex ducts shouldn&rsquo;t cause airflow problems in your home. However, because flex ducts aren&rsquo;t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren&rsquo;t tight enough, your HVAC could work twice as hard for the same air pressure. If you&rsquo;re worried about the airflow in your home, a rigid duct may be your best bet.</p></div>

Q: How do I service my HVAC system?

• <div><p>In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren&rsquo;t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.</p></div>

Q: What happens if you don't clean your AC evaporator coils?

• <div><p>If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.</p></div>

Q: Can a dirty air filter cause a high electric bill?

• <div><p>Yes, a dirty air filter can cause a higher electric bill. That&rsquo;s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the <a href="https://www.energy.gov/energysaver/maintaining-your-air-conditioner#:~:text=Replacing%20a%20dirty%2C%20clogged%20filter,in%20the%20air%20conditioner%20itself.">U.S. Department of Energy</a>, replacing dirty filters can save you between 5% and 15% in utility costs.</p></div>
